networking

[hoary wigeon]

yes

wifi security has gotten crazy good these days

[mellow hemlock]

That's good then. It'll be nice to deprecate the use of a Bluetooth Dongle and save another I/O slot

depri-
What's the word?

[random siren]

deprecate?

[hoary wigeon]

i have no clue

[mellow hemlock]

That's what I thought it was but then it sounded weird

[hoary wigeon]

depreciate is the antonym of appreciate (...i think)

[mellow hemlock]

That'd make sense as well

I mostly meant to say, to no longer require/use it

Ty two for the input

[twin pier]

maybe "retire"

[mellow hemlock]

That definitely also works

[twin pier]

deprecate is when you make something obsolete
depreciate is when something loses value as it gets older

[nova glacier]

Afaik, even the worst of WiFi vulns still required your device to have at least have one known network that an attacker could spoof to exploit it. You could disable WiFi in the firmware to stop such a hypothetical vulnerability though.

[twin pier]

Just get better neighbors at that point tbh

[opal pagoda]

Maybe you can disable pcie lanes in bios to the m.2 wifi card, Bluetooth should still work as it uses usb

[mellow hemlock]

The antenna take PCIe lanes? That might be a small issue since I plan on using all of the lanes

If disabling it is possible while still allowing for Bluetooth, then that's awesome

[pastel monolith]

Couldn't tell ya how many times I see people mix up these words

Tbf deprecation only a thing you really encounter with tech and depreciation a word I think most people are at least vaguely familiar with but is just kinda funny how often it happens

[nova glacier]

The lane it uses is neither physically shared nor is it switched. Even if it's freed up you won't be able to use it unless you make physical modifications to the m.2 connector.

[silent flax]

unless it is a CNVi (which is only on N100-300 based systems i think), then it is just an M.2 key A/E on every single board. Often hidden by metal shielding, but A/E key M.2 none the less

[nova glacier]

It's an x570, it's not cnvi

[silent flax]

literally a M.2 key A/E connector under the shield under the VRM heatsink near the dua 8-pin power

(going to be a problem to route it away from under the VRM heatsink, but not my problem)

[nova glacier]

It's always literally an m.2 a+e key. They still want to use the ax200 plugged into it for Bluetooth. They had thought they might get some pcie lanes if they disabled the wifi

[silent flax]

remove the 2 screws at the bottom of motherboard, remove module, vertical M.2 key A/E slot for free /s

[mellow hemlock]

That may be a problem then. I had thought it was fine.
32 lanes, 8 cpu 24 chipset, all 3 m.2 drive slots in use (x12, 2 nvme's and an x4 to sata adaptor), 2 gpus (x8/8; 16; 28 lanes) and my x4 capture card (32)

Only board that I've seen that is exactly what I'd need for my setup

[silent flax]

time to get a threadripper

[nova glacier]

At the end of the day there's really only 24 actual lanes on am4. 16x to 1 or split to 2 pcie slots, 4x for the first nvme m.2, and the remaining 4x being shared between everything else through the PCH (with the exception of 2x USB 3.2 gen1, 2x 3.2 gen 2 ports, and the audio).

If you switch to USB Bluetooth and unplug the ax200 from it's m.2 connector, you can hypothetically get that single extra physical pcie lane from the PCH but it sounds like you've already got your physical lane needs met.

[mellow hemlock]

By shared, do you mean that the single lane the wifi/bluetooth take wont disable or malfunction the other 32 in use?

And at worst will just maybe slow one of the lanes down?

Er, 24 rather since its just the chipset

[nova glacier]

It won't affect anything even if it's still enabled. The only physically shared lane on that board is between PCIE_2 and PCIE_4

[mellow hemlock]

And those are the x1's if I recall?

[nova glacier]

Yes

[mellow hemlock]

I am a bit confused I admit. If it were to be enabled, wouldn't that essentially mean I am running 25 out of 24 chipset lanes?

Wait did I get the cpu and chipset lanes confused? Which was 8 and which was 24?

[silent flax]

CPU has 20 (16+4) + 4 dedicated for to the chipset. Any other lanes then come from chipset

[nova glacier]

No, it's connected through the PCH so it doesn't use a CPU lane. AM4+X570 officially supports 36 physical lanes. 24 are available on the CPU and 20 on the PCH, though 4 on both sides aren't considered available

[silent flax]

16+4 on CPU, 8+4 on chipset. plus the itnerconnect between them which you should consider

normally i would say get Threadripper or at least this, but you would have to get creative. Two GPUs, one SSD on the board, one M.2 SATA adapter on board. Put the capture card to an U.2 to M.2 to PCIe x4 adapter, and use the bottom slot for dual M.2 adapter 🤷‍♂️

i mean soemthing like this 🙂

but not sure 10x SATA is enough

[nova glacier]

The chipset is 12 flexible (sata/pcie/usb), 4 pcie only, and 4 to the CPU

[mellow hemlock]

The Unify board also claims to support something that I have not seen on any other board as well. Its memory vendor claims that it can run 4x32Gb of Crucial's ddr4-3600 cl16. I have 2x so far.

[silent flax]

i ran DDR4-3600 CL18 4x32GB on nearly any AM4 board

maybe not officially, but i had no issues with it. At worst i had to bumb up SOC voltage to 1.1V

[mellow hemlock]

I can believe cl18, but this one goes to cl16. My understanding is that Crucial's ddr4 gaming ram is among the best there is for ddr4. Shame they stopped producing them

[mellow hemlock]

For this, does this mean that those unavailable lanes are lanes used for other things? Would the wifi be one of those?

[silent flax]

ALL DDR4 is stopped being produced. That is why price skyrocketed, and unless you got already existing parts, don't build on AM4

[silent flax]

unavailable = they are used to connect the CPU to chipset. you need them to be used for that

[nova glacier]

The wifi uses one of the 4 pcie-only lanes on the PCH, it's considered "available". Another one of that group is your PCIE_2/PCIE_4 lanes. I assume the third in that group went to the 2.5GbE. where the fourth went, idk (USB probably)

[mellow hemlock]

So the cpu has 20 lanes, and the chipset 16, excluding the 4 from each needed to communicate to eachother?

I wonder why I thought they had 32 usable lanes in total.. but it's 36?

[nova glacier]

Yes

[silent flax]

look at the block diagram picture i posted above and read it, please

no board is going to be without any SATA, so usually it is 32 which is distributed, because 4 are sacrificed for 4x SATA

[mellow hemlock]

I feel like that makes sense actually.

So I have been seeing 32 usable lanes excluding the 4 already used for sata?

I feel less silly about it now

[mellow hemlock]

I am trying to read it but I am struggling to connect what goes where. The chipset has 8 pcie lanes according to the top right panel wheras the cpu has 20 split into 16 for the two initial x16 slots, then 4 for the chipset downlink

[nova glacier]

It's a bit confusing tbh. The x570 actually has 4 dedicated SATA lanes, 4 dedicated cpu-pch pcie lanes, 8 pcie-only lanes, and 8 pcie/SATA lanes.

[mellow hemlock]

When you say pcie only lanes, what does that mean? Ie, lanes that can only go to pcie devices such as the x4 pcie slot and x4 m.2 slot?

[nova glacier]

Both of your PCH m.2 slots are using the flex lanes, so you could plug a SATA drive into them (though ofc don't waste an m.2 like that :p)

[silent flax]

the one i marked yellow are usually fixed (i have yet to see a board which the CPU x4 lanes uses for anything but NVMe M.2 slot).
The orange ones are pick one or another, and usually they pick one box as 4xSATA for boards with 8 SATA ports and the rest in "what layout our board needs", often as M.2 slot

so usually you get 16 via CPie from CPU, 4 as M.2 from CPU, then 8 as various PCIe slots, 4 as various devices (networking etc), 4 as SATA for 8 total SATA. Complicated i know 😄

[opal pagoda]

on all cards that dont use CNVio2 wifi part uses pcie and bt uses usb

[mellow hemlock]

So for boards that only have 4 sata slots, you have more room for customization?

[silent flax]

#networking message

[mellow hemlock]

I dont think that would be too viable for the case. I already do have most of the parts (I dont have the m.2 to sata x6 adapter yet for the third m.2 slot).

Just trying to think.. 36 lanes, 4 dedicated to 4 sata slots, leaving 32.. all pcie slots in use would equal 20 lanes (8/8/4), the three m.2's being 12(32), I'm struggling to wrap my head around it.
I must still not understand well enough how this all works cause I feel like it is implied that all of these devices would be fine even with the additional use of the x1 wifi antenna. Am I misunderstanding anything?

[silent flax]

alternatively just switch to USB grabber 🤷‍♂️

[silent flax]

you are missing the integrated devices. Network interface requires a x1 lane too for example

so two lanes on that unify board goes just to the networking interfaces

[mellow hemlock]

Jeez. Am I gonna have to sacrifice a thing or two to fit it all in?

[nova glacier]

No

[silent flax]

you can do grabbing via USB for example, that frees up 4 lanes right there

[mellow hemlock]

I admit, I am not certain what USB grabbing is

(Im gonna shower, I will return soon)

[silent flax]

literally an USB version of your HDMI grabber card

like https://www.avermedia.com/product-detail/GC553G2

so instead of this

you use something like this

[nova glacier]

You will be able to fit everything, but you'll be using 13/16 PCH pcie lanes (unused are PCIE_2/4, the wifi lane, and 1 other lane that's probably just not connected).
That's all being squeezed through the x4 link to the CPU, so it might experience some bottlenecks depending on total bandwidth usage of the nvme, SATA, and capture card.

I also second getting a USB capture card, that way it can use USB port that's direct to the CPU and saves a little bit of PCH bandwidth. I can't really speak to whether there's good USB capture cards vs pcie ones though

These 4 are your USB 3 ports that come from the CPU

[mellow hemlock]

You gave me an idea
Do USB-C Capture Cards exist? I already have uses for those three specific CPU-Controlled USB-A's, but not for the C

[opal pagoda]

Adapters for c to a are avalibile for couple of bucks

alternativly get a hub

[mellow hemlock]

I'll send a photo that I just made earlier showcasing my current USB Planning (It's before this convo so it still utilizes the PCIe Capture Card)

(It's incomplete)

For context, the Chipset USB Controllers would be passed into a VM, so only the CPU Controlled ones remain on the host. Hence why there's two KVM Inputs (one for each controller when the VM is active)

I am probably getting ahead of myself, I'll take a few mins to absorb everything said so far properly

[opal pagoda]

you can also break out internal ports

[mellow hemlock]

Maybe, though I'm not sure where I'd put them

Well, if I use a USB Capture Card, I could make space for the botton expansion slots I suppose

I'll see what I can find. Preferably, I'd really like to find one that lets me stream/record 1440p 60fps

I know some capture cards like to say they support certain Operating Systems, but is that really a consideration, or are all capture cards likely to be fine on Linux?

[pearl drum]

Whats faster motherboard ethernet or a pcie Ethernet card?

[mellow hemlock]

I suppose that depends, I'm not knowledgable persay but it appears that some boards have varying speeds (1gbit, 2.5gbit, up to 10gbit) just as some PCIe cards do

[pearl drum]

Yeah i guess u only really need a pcie card if ur internet is faster than ur ethernet port

[mellow hemlock]

That as well

[pearl drum]

Or ur just using ridiculously fast shit

[mellow hemlock]

Well not even - If your router plan gives you speeds faster than your motherboards ethernet port goes to, then I'd consider getting a PCIe Card of the speed you need

Or a board that naturally has that speed

[pearl drum]

Also should i get wifi 7 or 6e or just 6 for a wifi mesh system

Because im still unsure

[opal pagoda]

you cannot compare them like that
you can buy network cards of various speeds from 100mbps to >400gbps
built in motherboard ethernet is either gigabit, 2.5g or 10gbps depending on the model

[opal pagoda]

depends on the model
wifi 7 and 6 both have lots of optional features, for instance 6ghz and even 5ghz is optional for both but it isnt optional for 6e

[silent flax]

if it is same spec, they perform the same, as motherboard network cards are just the same chip soldered to motherboard instead of a PCIe card. The motherboard NIC is still connected through a PCIe connection, just as a dedicated card. The only difference is that PCIe connection is hardwired and impossible to replace. And motherboard NICs usually cap out at 10 gigabit

[mellow hemlock]

So uh, yeah
https://www.amazon.com/WAVLINK-2560x1440-passthrough-Ultra-Low-Compatible/dp/B0DDK73NYL
I think I'll be getting a USB Capture Card lmao

And that should free up any potential for lane bottlenecking

[lone crane]

800

connectx-8 my beloved

[clear igloo]

800>400 yes

[lone crane]

i just saw 400 and went for it

but anyhow i see the actual question and wow

like YES it does not matter but also like the ethernet chips on some boards should never have been made

imagine paying 1000$ for a board only to have unstable ethernet while gaming

[clear igloo]

eww, oh yah some of those chips suck or they have that "lan qos" garbage software included that tanks performance without people realizing why

These days the chips aren't usually an issue but I remember years ago that was a concern a lot of the time

[lone crane]

know of any cheap rj45 NICs on ali?

[clear igloo]

I've not really looked in a long time unfortunately

[lone crane]

dam welp ama give it a yolo

i should also grab some 10 gig switch

bit sad my UCG fiber only got 1 rj45 10 gig port

[clear igloo]

rip

[lone crane]

but 2 sfp+ ports

but no way in hell im using rj45 there

[clear igloo]

ewww, yah RJ45 10g SFP+ modules suck

[lone crane]

i got a 4 2.5 rj45 and 2 sfp+ port little unmanaged switch for like 30$ while a rj45 sfp+ thingy is like 50$ cheapest

[clear igloo]

yup, that too, haha

the copper optics are $$$

meanwhile you can get some MM optics for like the cost of a pack of ramen it seems

10g of course

[lone crane]

yup

you can do full 10 gig internet ethernet whatever for like 130$

i know since i did

2 connectx-3 cards with the little switch and 4 of the same sr sfp+ modual with some cheap as fiber cables

considering i closed the door on the ones i have i feel like it might be plastic

NSFN

[opal pagoda]

i have like 10+ of them in the office
they have so many usage limitations its crazy

[lone crane]

usage limitations?

[opal pagoda]

yep

[lone crane]

this is about the rj45 sfp stuff i was talking about right

[lone crane]

wait this is a full fat enterprise switch that does not even have enough power to power all of its ports

[opal pagoda]

yes

[opal pagoda]

it has fkn 2x750w psu's
i believe it is more bc of cooling

[lone crane]

yeeeaaa that unmanaged switch i was talking about should not be used with any rj45 sfp+ stuff

5v 1a

and no real cooling

[opal pagoda]

half of power budget just for sfp+ transciever

[lone crane]

rj45 is so sad

sfp+ is so much cheaper to implement from my understanding even

i so badly want motherboards to come with sfp+ at least and it being built in

[opal pagoda]

yea, you offload everything to transciever itself

[lone crane]

even there they cheap af and ofc there is passive dac

or can just do active dac

[opal pagoda]

or just use fiber and get flexibility

[lone crane]

plastic fiber yea

[opal pagoda]

no, mm

plastic fibers suck ass

eg. toslink

[lone crane]

well toslink is also MASSIVE

[lone crane]

it claims to be fiber but i have a hard time believing that considering im still getting good speeds

[opal pagoda]

it is fiber

around it is kevlar

[lone crane]

well i can see the fiber

[opal pagoda]

and even if it breaks it is mm so it just hops over the air gap

[lone crane]

i wanna see what speeds im getting now

[opal pagoda]

can you take less blurry photo

[lone crane]

well i have eyes

it 100% is the fiber but sadly that was taken a while ago

[opal pagoda]

you can use vfl to see if it is actually broken

[lone crane]

well

[opal pagoda]

if transcievers have DOM functionality you can look at fiber light loss

[lone crane]

it has DOM but i got no clue how to use it

[short lance]

why do people put noggins in the wall

[lone crane]

like this?

[opal pagoda]

show interfaces transceiver

[lone crane]

something is defaulting to 2.5 by the look of it

[opal pagoda]

no clue on how to do that on ubiquiti as i have never used it

[lone crane]

this is as much info i get

welp im getting my 5m cable tommorow

well ok i can ssh into it and do some stuff so i can kinda see it but well yea no im not gonna bother

[frosty stone]

Pfft, that's nothing. The fiber going into my ONT is snapped and only works in certain positions, discovered it's been like that since it was installed in 2020 when we moved it last year

[opal pagoda]

Thats just called angle dependant attenuator

[frosty stone]

[pseudo blade]

Man these air fibers suck

[coral marlin]

Anyone have an actual written guide ( outside of the documentation) for checkmk raw SMTP setup with an on-prem exchange ? Official docs are confusing and my knowledge of SMTP is limited. I know it's for emails but brah...That documentation cannot be any more vague and confusing...

[topaz patrol]

Why are you using exchange for that?

[coral marlin]

Because my boss is too old to rely on cloud solutions...

[ornate jungle]

I would not recommend relying on Email for IT-related alerts. Neither would Checkmk...
https://docs.checkmk.com/latest/en/notifications.html#:~:text=delivery per SMTP-,6.1. Email is not reliable,-Monitoring is only

[ornate jungle]

Anywho, it looks like Checkmk supports sending emails using a properly configured SMTP relay server. We finally did away with our on-prem Exchange this year and now run a Postfix instance for internal emails.
https://docs.checkmk.com/latest/en/notification_rules.html#smtp

[dreamy sonnet]

Hello. Unfortunately im moving to a place without fiber, and have to resolve to a 5G router with limited signal. I can see the ground tower, but the router itself would have to go through a house. The provider i will be trying out does NOT include an external antenna, and the others use a flat box antennas like the zyxel nr7302. I thought of putting one on the roof, and since it from the roof would have near perfect line to the tower (1 km away), i thought of maybe doing a dish antenna. Now, heard about ubiquiti and thought of their airMAX 5GHz 30 DBi RocketDish. Is it ok? Any better or equal which are cheaper?

[lone crane]

look what my isp was so nice in doing

[pseudo blade]

Don't use ISP DNS then lol

[lone crane]

a

AAAAAAAAAA

[lone crane]

it was the first thing i tried

[pseudo blade]

8.8.8.8
8.8.4.4
1.1.1.1

<DoH equivalents>

[lone crane]

iophyoiujewghfoigusargho

[pseudo blade]

Well you've done it wrong then

[lone crane]

i have cloudflare first then google

[lone crane]

yes very wrong

[pseudo blade]

Use DoH

[random siren]

been using DoT instead of DoH. any advantage of using DoH?

[lone crane]

i has somehow done it

[mild whale]

That dish is like $109, idk that you'll do much better.

I would probably suggest that precision alignment kit though.

[opal pagoda]

Are you signing up for a wisp service or 4g/5g?
that dish is only compatabile with 5ghz tipically used by 802.11a or 802.11ac wifi

[mild whale]

Oh I see that now

Good catch lmao

[opal pagoda]

First try using it without external antennas, if you get bad signal then look at directional 4g/5g antennas with appropriate mimo count, tipically 2x2 (2x sma) or 4x4 (4x sma)

[mild whale]

Yeah, you need an antenna compatible with the frequency band that you are looking to receive.

[mild whale]

Sorry, wasn't me asking i just pulled up the datasheet and completely overlooked it

I pulled the rookie helping mistake ):

[opal pagoda]

Ah yes @dreamy sonnet is who i am reffering to

[mild whale]

I was somewhat puzzling the reflector since you dont normally need those for cellular

Now that dish makes me want to see how far I can get wifi

[sly compass]

I currently running 10gbe over rj45. How would i make something similar with fiber? Are there outlets for lc?

[clear igloo]

lc keystone jacks definitely exist, yes

[opal pagoda]

you can use all kinds of antenna designs to recieve any radio signal

commercial dish for 4g: https://mikrotik.com/product/lhg_lte18

most cheap omni antennas are dipole tho

[sly compass]

I just realised that keystone is a standard and it even exists usb, hdmi and more

[clear igloo]

Welcome to the future 😄
Keystones for everything!

They really are amazing too, take a 4 or 6 port wall plate and you can do just about anything with it 😄

[sly compass]

Not that i have a use case for that, but i think about the future, an rj45 10gbe jack and next to it an lc fiber jack. 100gbe and basically future proof forever

I mean that cable should easily manage millions of gigabytes per second if you have the hardware

[clear igloo]

Single mode, yup 🙂

[sly compass]

Sucks that it doesn’t have any power

There should be a new standard with three coppar wires in one plug

[clear igloo]

Don't make the mistake of going multimode, unless you want to run MPO cables and that's a whole other ball of wax

[sly compass]

Yea i looked at that

So messy

I guess multimode is basically only for datacenters?

[clear igloo]

multimode is low distance, generally within a row

[mild whale]

Ye, like I said, uncommon. An antenna design like the airmax for LTE would be very weird, as its not a typical setup. You're in microwave territory with wifi.

[clear igloo]

top of rack switch to end of row kind of thing but even then single mode is basically the same price and you don't need to rip and replace every time you need a new standard. OS2 and you're basically set for the future with singlemode

[opal pagoda]

rack to rack, within same row

intra-rack dac cables are tipically used

[pseudo blade]

You can get LC keystones yes

Damn it Discord didn't scroll and my response was redundant

[thick minnow]

What is this use of this cable?

[coral marlin]

I tried setting up Postfix as well. But for some dumb reason it's not sending e-mails 🙁

[lone crane]

wrong answer only?

[thick minnow]

No, real answer please

I asked my supervisor and he had no idea

[lone crane]

what

[thick minnow]

Im serious

[lone crane]

how are schools not teaching this

[thick minnow]

Its a Y-splinter, for ethernet? How does that work

[lone crane]

there are 4 pairs in there, probs 4 pairs for one thing and 4 for something else

[thick minnow]

VoIP?

[lone crane]

also thank god i thought you meant the cable itself

well port

[thick minnow]

No i know its a UTP cable

[lone crane]

How many of the pairs of wire available are used depends on the protocol used for the physical layer which will determine your transfer speeds. 100BaseT will only use 2 of the 4 and in theory you could certainly split it off on both ends and have 2 100Mbit full duplex cables to your router, but you'd still need 2 ports on the router for this, as you'd essentially be making 2 half cables out of one that will only support 100BaseT on each "cable."

[thick minnow]

I mean, cat3 used RJ11 because it only needed 2 pairs

[lone crane]

but yea no that stuff is insane and not used for modern networks

[thick minnow]

For example

No wait this is 3 pairs

Im even more confused now

[lone crane]

hey look even LTT made a vid https://www.youtube.com/watch?v=QgrVVyIzecM

[thick minnow]

This building is old, like 1960s old, theres still Coax and the token ring type 1 connectors

[lone crane]

well ok that video is not great

anyhow probs just a split kinda system

[thick minnow]

This bullshit

[lone crane]

xd

[lone crane]

but this looks to be what that cable might be doing

[thick minnow]

I see

Thanks for helping

Also, school do absolutely NOT teach kids what a UTP cable is

I’ve heard it being called a WiFi cable

[lone crane]

o no

we were not taught too

[opal pagoda]

Might be wireshark tap

[lone crane]

aaaaaaa yea true

[opal pagoda]

but it is impossible to tell without mapping it out with a cable tester

[red oracle]

Could just be a hub where the same signal is sent through both cables

If it is, that would be really dumb to use vs a simple switch.

[stuck grove]

wouldn’t function

[red oracle]

I see no reason why not. That's how hub devices work.

There's a reason we don't use them anymore though. Switching is easy these days and much less stupid.

[stuck grove]

Hub devices don’t function for ethernet at all, LTT literally made a video about this exact topic

[red oracle]

Hmm, the Cisco material I learned from only really glanced over the topic of hubs so maybe I'm wrong? I didn't think so though...

[twin pier]

not at full speed, but they certainly exist

[stuck grove]

You’d have to split the cables into 2 twisted pairs instead of 4, which would be cat4 speeds

[red oracle]

This type of device.

https://study-ccna.com/network-hubs-explained/ I no longer have access to the NetAcad pages I read on the topic, but this covers it decently well

[twin pier]

what makes 4 pairs not work

[stuck grove]

i mean a, it would work just only at cat4 speed as previously stated, b, that’s not the scenario that was stated earlier

Could just be a hub where the same signal is sent through both cables

is the claim being discussed

[twin pier]

All I saw was a cable split it half. Maybe I missed some context

[red oracle]

Anyway, I do not know what the cable does for certain, but some sort of weird wiring like a hub doesn't seem too farfetched to me.

[mild whale]

I've seen these around PLC's. It is a splitter for 10/100 Ethernet/IO. Uses two twisted pair sets instead of 4.

You can reuse the cable for one long cable run instead of using two. You'll see them in control cabinets sometimes.

Pretty obsolete now though.

[lone crane]

like 5$ for a gig switch

[opal pagoda]

profinet fuckery walks in

i was so confused when i was asked to configure voip for a plc port

[mild whale]

lmao

you aren't using a $5 switch in industrial automation. if you are, quit that company because it'll be 1am when you get a call saying the whole factory line is down

[lone crane]

ofc

just saying there are 1gig switches for almost nothing

[mild whale]

gotta love profinet

it's Ethernet but not

spicy ethernet.

[opal pagoda]

cheaper industrial switches for less critical applications exist too
this one is 55 euros

[opal pagoda]

Its just wierd qos things, otherwise it is compatible with regular Ethernet

[mild whale]

A lot of the time it depends on what you're allowed to use. if you need something that's guaranteed to work with whatever it is you're using, you might just be spending the money.

as the integrator I'd always make sure to spec the best possible so long as they're willing to pay for it. saves a ton of money down the line.

[lone crane]

i do kinda wonder what makes it so spensive

[opal pagoda]

temperature rating, possible radiation hardening, and lots and lots of certifications and long term testing

various aprovals for enviromental conditions

[lone crane]

i was thinking it somehow was more like every port was redundant somehow

[opal pagoda]

at the end this switch might end up in either of these conditions

• a electrical cabinet with built in air conditioning
• random ass electrical box without cooling in a 50c ambient temp and heavy dust in the air

nope, you are paying for enviromental resistance and for someone to stand behind that enviromental resistance

ive been having dns issues all morning i flush the dns cache it works until i restart the pc again then i have to do that again normally the next day i have static dns for 8.8.8.8 googles servers i did it with 1.1.1.1 cloudfare what could be affecting this? its sudden no new apps nothing have been installed

[sly compass]

Any suggestions for software that i can self-host and is free with a gui that can do remote execution like puppet, salt and chef. Im currently trying theforeman with katello. Feels like docs could be better but working on implementing it. Any other suggestions?

[mild whale]

Yeah, its the rating for industrial environments.

Manufacturing is dirty, smelly, and will break most sensitive electronics very quickly

Stuff is hopefully made to last those conditions with very little maintenance required.

I did a steel mill once, and that absolutely would destroy anything consumer grade

[peak cloak]

I'm working at a recycling paper mill, everything on the fiber side (turning raw old paper) into fiber is wet and full of paper stalactites

Meanwhile on the paper machine, it's also wet and dusty

[opal pagoda]

Water and humidity is the worst
I am lucky that i don't have to worry abt it since it is not used in our production except quality control

[lone crane]

i know the best fix for it

buckets and buckets of epoxy

[hushed sandal]

just picked up a cisco sg350x-mp. the 10g ports will only connect at either 1g or 10g, which apparently is common. my computer is will do 2.5, if I buy a SFP+ module off aliexpress that supports 2.5g, will i get the full 2.5g on my computer or will the switch force the module to 1g like it does on the rj45 plug when I try to do 2.5g?

[ornate jungle]

Depends on how the switch handles the SFP+ module. The switch documentation should say this somewhere. It should also list SFP+ modules that are compatible with it. (Not all modules work in all vendors gear.)

[clear igloo]

Some SFP modules that do nbase-t will also mask themselves as 10g and do some thing to support 2.5g on the client side but they're pretty iffy

[opal pagoda]

just get 10g card for your pc and use cisco or cisco coded transcievers on the switch side

if you use rando transcievers it will not work by default

[hushed sandal]

that is a much better idea, a 10g nic should work no issue, but a rando transcevier is going to be questionable. i should of thought of that too, was so fixed on getting the switch side to work, didn't think about the PC.

[hushed sandal]

reading the cisco dumentation (can find any mention of supporting 2.5g modules), i do need a transceiver that would do exactly as you say, but you are right, it would be iffy, probalby end up buying 3 or 4 before i found one that worked... 🙁

[clear igloo]

I've had some, they show up but throughput was wonky

[hushed sandal]

As martin suggested, I think im better off being in the market for a 10g nic 🙂 even faster...

[clear igloo]

yup 🙂

faster and probably just as much in the end with time factored in that you'll save with hassle

[hushed sandal]

exactly

[opal pagoda]

Also if you dont absolutely need to go through rj45 get a dac if under 5m or 2x 10g sc transceivers and appropriate length om3 patch cable

Sfp+ 10g base t are very power hungry and run hot af

[lone crane]

if possible always try to go SFP+ if its a homelab

[gusty dove]

Is it worth using Wi-Fi over Ethernet when the router is literally <5 feet away for a "cleaner" setup with less wires?

[amber urchin]

wifi is for portable devices IMO

[gusty dove]

I mean, the distance seems too short for almost any sort of interference.

[silent flax]

others can cause interference with anything wireless, cable is always better if you can do it

[amber urchin]

It's not just interference it's the topology. wifi is sorta like having every device on the same wire. This leads to higher and inconsistent latencies.

Is it significant? Not usually. But it's also something that is so easy to fix by using a cable.

[opal pagoda]

No, wifi is using shared medium with phones, tv, iot crap, etc which all use airtime, Ethernet has no such issues

[lone crane]

my rule is, if it can use ethernet, use ethernet

[ornate jungle]

Not really - if you can hardwire something, you should. The more devices sharing the airwaves, the more chances for collisions, or rather, the harder your devices must work to avoid collisions.

[lone crane]

wifi as a backup on a pc is smart

i got 10 gig but due to some issues with the wires in the wall it is unstable at times but i have wifi on so when it cuts out i do not get kicked out of a game

[opal pagoda]

last week i had a access control reader malfunction
reason: bad IP stack and it was sending routed packets to individual HSRP member mac instead of HSRP virtual mac address

wireshark <3

[dreamy sonnet]

So much talk since i wrote so imma try again. Im unfortunately moving from a location with fiber, to one without. Having to resolve to 5G router. Now, i found out the router the ISP i chose doesn't support external antenna, I perhaps have to look for a router myself. I need recommendations for a router and possibly an external antenna (dish antenna) that support 5g sim.

I have also been recommended Starlink. I would like to know how Starlink usually is with latency. Their map says 30-50ms, also reported by some in my country. But i also read about often spiking due to satellite changes. Thoughts?

[opal pagoda]

whats your budget?

[mild whale]

why a dish?

it doesn't really work that way. MIMO would require multiple dishes, not just one.

log-periodic array, they're cheap and work well.

https://www.waveform.com/collections/antennas/5g-antennas

something like thse.

they do have a "dish," but that, too, is just a log-periodic with a parabolic reflector; it's overkill if you're only a kilometer away lol

this antenna looks pretty good. https://www.waveform.com/products/dualplus

[opal pagoda]

https://mikrotik.com/product/atl_5g_r16
Get this if you can afford it

People often overlook attention in the coax cables to the antenna

This is especially the case with thin ones that often get included with cheapo 4g 5g antennas

[mild whale]

also worth it to know what coax cable they use.

different impedance can cause issues, which my guess is where a lot of people have connectivity/signal issues

A lot of what he should pick depends on how bad the reception really is

"5G" covers a large amount of the frequency spectrum nowadays, so it really depends on what the area is receiving. could be anywhere from 800MHz all the way to 4000MHz.

[royal kite]

is anyone really good at 3d modeling? i am making a server but instead of spending money for a rack mount i want to connect them with an adapter so i can just 3d print it

[opal pagoda]

just get a piece of angled steel and drill holes every 0.625"

[peak cloak]

Or learn cad isn't not too difficult

Onshape or fusion have food functionally for personal use

Or freecad which is not as easy or intuitive for a beginner

[mild whale]

wood screws and a 2x1

or even 2x4

if you really want the vibe, go for a 4x4

[shut geyser]

ok, fellow geeks. I am relatively new at networking and am trying to optimize my wifi signal to my home office.
I am using wavemon to get a view of the connection quality and sig strength.

I notice that my signal level bounces between -46 dBM and -37 dBM
My quality Link Sits consistenetly at 100%.

My router is on the main floor and I have an extender just outside of my office.

Any advice on what I can do to stabilize the signal level? I am trying to ultimately get it at -37 or better consistently.

[nova glacier]

the signal level here is a red herring. It is your strength to the extender, not the wifi router. It's also already HE-MCS 11 (1200Mb/s), the signal can't get any better than that without hardware upgrades.

That's not to say there aren't steps you can take to optimize the network, but you'll need a different tool called iperf to assess the changes you make. You'll need to have a device connected by ethernet cable to the wifi router to run an iperf server. From the PC in the home office you'll use iperf as client to connect to that server. Then you can move the extender to new positions and rerun the test to observe the true network performance. I recommend also testing with the extender unplugged, because there are conditions where an extender actually reduces performance despite the "excellent" link quality you might see on the PC.

[pseudo blade]

WiFi range extenders are often a curse in disguise

Almost all are not equipped with two 5ghz radios and must do all communications on a single channel

[shut geyser]

ah. I was thinking that my link quality was the signal strength to the extender. So, that is very insightful. I will do what you said and try removing the extender to get a better understanding on whether it is helping or hurting my connection. And I'll look into the iperf. I am not familiar with that, but you've pointed me down a road. Much appreciated!

[shut geyser]

does it matter if the extender is set up as part of a mesh network?

[pseudo blade]

Not especially, it's the hardware and signal quality that matter

Mesh network devices do usually offer better support for switching between access points

[nova glacier]

the extender's capabilities are just what they are, whether used as a mesh or standalone

but yeah, at least a mesh is more seamless in user experience

[nova glacier]

it's fairly easy to do. You'll just need to open port 5201 on the server that you run iperf3 --server on if it's got a firewall enabled. Then on the client you run iperf3 x.x.x.x replacing x.x.x.x with the local IP of the server

[cunning lion]

sighs yeah this isn't right

Yeah paying for 1GB connection but getting less than 10%

[twin pier]

bad ethernet cable linking at 100base-t?

[cunning lion]

Cable that came with it

[peak cloak]

in windows check what the link speed is

[cunning lion]

I am on my phone and that Speed is what is happening between the modem and the router so has nothing to do with my personally devices

@peak cloak

Also all the devices in my house are connected via wifi to the router while the router is hardwired to the modem

[peak cloak]

could be a spectrum issue but one last check

check the WAN link speed in the router

[cunning lion]

There is no way to do that with the "app"(just a web page) to do that

Spectrum gives us honestly zero info and zero control over either device

[peak cloak]

if it's a spectrum router then yeah complain to them

[cunning lion]

Restarting the modem itself seems to have fixed the issue

First one is between moden and router second is to my phone

[mild whale]

Is that the Wifi 7 toilet bowl thing they've been shipping?

[cunning lion]

https://d15yx0mnc9teae.cloudfront.net/sites/default/files/Spectrum D3.1 EMTA Data Sheet(1).pdf modem

And router https://d15yx0mnc9teae.cloudfront.net/sites/default/files/2023-06/20230413_WiFi 6E User Guide.pdf

Ours is 6E

[mild whale]

looks like an air freshener

I've got spectrum too, and I don't use the included router they gave

I have a linksys one that's been pretty rock solid for like two years now

when they upgraded us to 1 gig, they gave the same modem

i just swapped the modem for the new one and everything just worked, so

[carmine matrix]

I’m looking to mess around with packet sniffing and intercepting 4 way hand shakes and other things that come up on learning security. I use an Apple M4 MacBook and want an adapter that has all the best features. What’s the best usb WiFi adapter I can get for this?

[shell remnant]

spoted out in public

[sharp oak]

Is there any router that could cover roughly 6500 SQ ft as a single unit? Preferably a outdoor ready unit as I wanna put it on a pole outside
I don't think it's possible but Poe would be a NICE bonus cus then I don't gotta pull wire through the conduit

[sharp oak]

Use the spectrum app to do a speed test NOT a website it's still a ookla speed test but it's tested on your modem instead of the router

[stuck grove]

only 2.4ghz spectrum could even imagine doing that

[sharp oak]

Idc about speed if it's at least 100mbit

[frosty stone]

Even this massive thing is only rated for 5000 https://store.ui.com/us/en/category/all-wifi/products/uwb-xg

[sharp oak]

Might have to go with this

I've got a 12ft antenna pole with a cat 6 connection run to it from the server room I wanna put a wide range router or access point on

Gonna run 1080P security cameras so bandwidth isn't a big concern

[random siren]

if you wanna run security cams on that wifi, why not run poe cables to them instead of just power? or if there is power already there, why not run powerline over it and then a more closer accesspoint or just ethernet to the cam?

[nova glacier]

That's a 90° directional 5GHz-only AP for wifi at stadiums and such. It's intended for obstruction free scenarios. Anything with 5000+ sqft is going to be directional. Omni directional maxes out more around 2000sqft. Considering you were about to spend $1500 on an AP, why not just get 3 or more U7 (Pro) Outdoor units?
https://store.ui.com/us/en/products/u7-outdoor

[sharp oak]

I'd have to trench, run conduit, and cat cable

and if its not POE then I also gotta run romex or sc

[nova glacier]

I think you replied to the wrong person

[sharp oak]

u replied to me 😭

[sharp oak]

this isnt on a building its a pole 300ft away from the building 😭

[nova glacier]

Why would you need to trench to put up multiple APs. You can just put them all on one pole pointed in 4 directions. You'll need to do that for that $1500 unit too, it's a 90° 5GHz directional. The u7 (pro) outdoor is a 90° 2.4GHz and 45° 5GHz directional

[sharp oak]

oh I thought you where saying get normal shorter range APs

would trees interupt the range because the pole is in a 19x19 ft clearing in the forest lol

I've had people burning shit in my woods

(and my buisness is really close by)

[nova glacier]

Yes. The 5GHz would unusuable in a tree filled forest. 2.4GHz would function better, although it will still be reduced range.

[sharp oak]

I think it'd be easier to just put up a bunch of cheap RTSP solar cameras than run hundreds of yards of cat cable underground

I've got some 5" timberlok security screws I was gonna put them on trees n shit and then put the solar panels up around the top (I've got a 4x4 man lift so its not hard)

(corded cameras are using cat cable 😭)

[nova glacier]

Would the cameras would be in all directions from the pole?

[sharp oak]

oh I've got a good 3 square miles to try and cover 😭

wayyy further away than the pole I was gonna put them on trees

back in the 1990s this building had a satelite pole and we pulled the bnc cable out to put a cat 6 double shielded cable in last year but the current AP (poe) doesn't have enough range to run stuff more then like 150ft away

[nova glacier]

then yeah, probably 4 u7 outdoors on that pole. You could maybe try 3, if some gaps would be okay due to the positioning of the cameras

[sharp oak]

prob could get away with 3 since the building cameras can see like 20 ft before that pole so

I've got a box of mabye 30 or so LTS LTC cameras I was gonna use

worst case I shell out $750 x 20 for their mesh wifi routers for those cameras since they're solar capable too

[nova glacier]

ubiquiti can mesh too. the u7 outdoor needs only 19W max at 48V (42.5-57V) so it can be powered from a solar battery bank easily. It's hard to guess without knowing the terrain and tree cover, but I'd bet you'll only need a 1-4 remote nodes to get complete coverage (if you need any at all)

[sharp oak]

its mostly basswoods and champions so I can just knick off a few branches at the top where you cant see them and put a solar pannel in lol as long as 2-3 hours of direct sun is enough for full charges

I've already done this in a few places 8-9 years ago its only now getting to the point I need to get my chainsaw and go up there and take 6 or 7 branches off again

and its not massive (the ones I have up there are like 15x12 iirc)

just run a 20-30 foot cable up the tree and tack it down every 2 ft with screw in clamps and 2 inch deck screws is what I did personally lol

[pastel monolith]

Know you already said have cameras and whatnot but this could be a good use case for practical quadcopter too and might be simpler than maintaining network in the woods for bunch of cameras. Your probably want something with infrared camera which is gonna be basically commercial quadcopters (like some of the more industrial DJI stuff) or diy (iNav, pixhawk, or ardupilot are all more open platforms with some advanced support and companies that build custom solutions for commercial things around em). Effectively if have open field area can just take it straight up and scan around from the top to see where there's smoke/fire. Navigating trees isn't easy but can work for just getting top down view of things for quite a distance.

[pseudo blade]

Significantly, trees are dense and mostly water, which absorbs signals.

You have to get clear line of sight by either going taller or finding different angles.

[sharp oak]

my NVR urns for more inputs

[pseudo blade]

That said, the radius you're asking is like 45 feet?

[sharp oak]

(I bought 3 56 channel NVRs and only have 48 cameras across the same property)

[sharp oak]

300 ft, but I wanna inevitably cover the whole property

would it be more worth it to just put up like 60 APs across the property inside concrete boxes in the ground?

[pseudo blade]

300 ft radius is much, much more than 6500 sq.ft

[sharp oak]

grah

would it be better to just get cheaper APs and put them in water proof meter boxes in the ground every 60 or so ft?

[pseudo blade]

282,000 sq.ft

[sharp oak]

that'd only require 2800 sq ft APs right?

[pseudo blade]

I can do that radius just about on a single device with a 4db antenna with no obstructions

And very easily on a good omnidirectional antemna

The problem is your obstructions

[sharp oak]

probably better to just trench out conduit and run APs everywhere then?

[pseudo blade]

Oh, not necessarily

[sharp oak]

cost is a major factor I've litterally got thousands of feet of 2inch PVC conduit 😭

[pseudo blade]

It just needs you to go and do some observations of line-of-sight from where your NVR is to the middle tower point, to where your cameras are

[sharp oak]

I could probably buy like 20 cheap 2800sq ft APs for the same price ngl

[pseudo blade]

Then wherever you don't have line of sight, you have to move stuff until it does, or get more height

[cunning lion]

That was the My Spectrum apps speedtest

[sharp oak]

the cameras just run on the normal network with their own subnet (192.168.19.x)

[sharp oak]

I don't think I can get more height above 60ft tall trees at the shortest

[cunning lion]

the app itself is just a crappy webpage

[pseudo blade]

You have to work around them then

[sharp oak]

yeah thats why I think a bunch of APs might be the best option tbh

[pseudo blade]

How many cameras, first?

You don't need blanket coverage really

[sharp oak]

20 or so now but I intend to add like 90 down the line 😭

[pseudo blade]

You just need it in specific spots

[sharp oak]

• eventually we're gonna cut down trees here anyways and pave it for expanding the vehicle yard

[pseudo blade]

90 cameras in that radius is nuts and adds significant bandwidth requirements

[sharp oak]

1080P signal only takes like 12mbps iirc?

[nova glacier]

directionals in strategic locations would be sufficient. You could have directionals point towards remote optimally placed omni-directional(s)

[pseudo blade]

12mbps*90...

[sharp oak]

thats 1080

[pseudo blade]

I'd hate to imagine the NVR setup for that too

[sharp oak]

I've got cat 6a run rn so at that 300ft from building to the pole (the wire length is 319ft)

[pseudo blade]

Most setups I see are much lower bandwidth

[sharp oak]

iirc you can run 10 gig on this?

[sharp oak]

I've got 3 56 channel NVRs that have a 5 gig uplink each

and they're conected into 10 gig switches so there is a choke for sure

[pseudo blade]

Tbh if you're talking 90 cameras get a consultant to survey your grounds for you

At this point they may actually save you money

[sharp oak]

I know how to run everything and where I wanna put everything I was just wondering if an AP that can do that exists

[pseudo blade]

Yes but you don't know outdoor wireless site design and it's very scenario dependent

[sharp oak]

ill probably just run 8/2 romex and cat6a in conduits every 60ft and put APs in for now since eventually this area is getting paved anyways and ill need the 8/2 for the light poles

[pseudo blade]

Make up diagrams of what you want using a map of the location and ask someone to design a network for you

[sharp oak]

I went to school for building network design 😭

I know how to do it I'm just trying to get ideas rn I haven't done networking in a decade

[pseudo blade]

When I did this for big farms for my old job I was very insistent on having a ton of pictures and diagrams

Because there's factors (like wanting 90 cameras) which play in big

[sharp oak]

10G is overkill for that

everything involved with this besides the NVRs is 10G

[pseudo blade]

You're exceeding gigabit

[nova glacier]

https://store.ui.com/us/en/category/wifi-bridging

ubiquity does also have these for linking up longer gaps between areas, if necessary.

[sharp oak]

10 gigabit is overkill 😭

[pseudo blade]

I don't know what has you thinking the WiFi parts to your cameras have anything to do with 10 gigabit

[sharp oak]

its barely exceeding gigabit you'd typically use a 5 gig connection for this at the most I just used cat 6a at the time because I've got a 2500ft spool in the storage building rn

[sharp oak]

I'm saying theres a 10G line?

[pseudo blade]

Cool

[sharp oak]

I could easily use a 2.5G AP without issue

[pseudo blade]

Not relevant

[sharp oak]

wdym not relevant a 2.5G AP is more than enough for that

[pseudo blade]

What type of radio does your cameras have

[sharp oak]

checking the manual rn

[pseudo blade]

Is it by chance 2.4ghz WiFi 4

[sharp oak]

Wifi 6

[pseudo blade]

What does peak density of cameras look like and how far will they be from your tower?

[pseudo blade]

You're not getting 2.5gbps

[sharp oak]

between 25 ft and 250 ft

[sharp oak]

why would a single camera need 2.5G?

[pseudo blade]

You're missing that they'd be sharing airtime

[sharp oak]

also wifi 6 has a max speed of 9.6G 😭

[pseudo blade]

Not for you it doesn't

[sharp oak]

real world it maxes out at like 2.8G iirc

[nova glacier]

1x1 80MHz is just 600Mbps, which is what I would bet the cameras are

[sharp oak]

the manual says wifi 6 with legacy support for wifi 4

[pseudo blade]

And that's more than real world speeds even under near ideal conditions, much less one like this

[sharp oak]

again they're going to run 1080P 24f streams :sob;

that is like 12-18 mbit

[pseudo blade]

You know what? You clearly know what you're talking about and don't need our input

Why don't you run off and go implement whatever you think is best

[sharp oak]

asks about a AP that I don't know if it exists beacuse everything is really consistent about it
completely unrelated conversation

[nova glacier]

you'd also be using 3 or more APs in any case, so it's just 32 cams per AP. It should actually be viable from a bandwidth perspective imo, though terrain and trees is an x-factor that could make it non-viable

[sharp oak]

yeah I'm probably just gonna end up talking with my general contractor about the possibility of running conduit and stubs for the light poles that will end up needing run anyways in 3-5 years and just do that now if possible and put APs onto them

cus eventually a good 1/8th of this area is becoming a parking lot anyways

the rest I could probably just do the same with our general build/expansion plan guidelines

less work (logistically) and simplier to just add on 15-20 APs

[nova glacier]

Just don't overdo it. You don't need a ton of overlapping APs. 20 APs is highly likely extremely overkill

[sharp oak]

the general building plan would call for 55ft spacing between poles so 2600sqft APs shouldn't overlap right?

[pseudo blade]

Nah leave them to it, it's just 12mbps lol

[sharp oak]

actually no I'm stupid that would uhh

[twin pier]

what the heck are you doing to want 20 aps for

[sharp oak]

I have a 96 acre property 😭

[twin pier]

that sounds large

4 million square feet

[sharp oak]

its got my house, 2 commercial buildings, run a 60 vehicle and 25 vehicle parking lot, the barn, 2 storage buildings

[nova glacier]

a directional 90° 2.4GHz outdoor AP can reach 600+ft in front of it without obstructions

[sharp oak]

yeah but I'm tryna factor for works NOW not in 2-3 years

[nova glacier]

you're still going to be getting several hundred ft easily

[sharp oak]

i could get all that trenching work for the conduit done with 2-3 people in a few weeks

I'd probably just mount APs to the photocell slot on each light pole in the future and just use like a 8ft stub for the time being ngl

the photocell slot is just a standard single gang juntion box

wonder if anything exists like this for outdoor ubiquiti hardware?

[twin pier]

it looks like the main way to mount is these clamps that it comes with, that go around a pole

ive never had any outdoor hardware

[sharp oak]

I dobut they'd go around a 28 inch diameter pole lol

[twin pier]

probably not

[sharp oak]

and light poles have 2 good places to mount things directly anyways

[nova glacier]

looks 3d printed, so I'm sure someone could adjust it for the u7 outdoor

[sharp oak]

defo will have to look into that

[lone crane]

Look at what I found on Reddit

Ain't it fun

[dreamy sonnet]

Why a dish. Idk. Higher DBi. I have almost a clear path to the ground antenna from my roof. I would be above the house sitting in between. Only a tree where the branches stretch out between. I don’t think i was gonna go for MIMO(?) thats multiple antennas right? But between my house and the antenna is an another house. Thats why i would like to use an external antenna instead of the router. + i’m gaming so delay is huge deal

[dreamy sonnet]

Quite expensive.. too much for me unfortunately. How would frequency work? Says here the 5G in my country runs between 700MHz and 3400, is it just specific frequencies or is it the whole range?

[dreamy sonnet]

So you recommend a LPDA antennas? Can you explain why? The DBi is similar to Emcom Xpol-2 which is used by one of the ISP’s here

[opal pagoda]

Go to cellmapper and see which band tower uses

[opal pagoda]

I have used mimo lpda antenna mimo pair, ended up installing it at a friend's house and his connection improved soo much

[mild whale]

A dish is tuned for a very specific frequency, not an entire range. 5G spans between that range in different channels, so if you are pointing a dish at the wrong panel, you may not get very good signal due to hand-off or load balancing between transmitters. This is due to a Dish's very narrow beam width.

Most 5G base stations are 2x2 or 4x4 MIMO. This increases speed and reliability. You need one antenna per, so for 2x2 you need two dishes. Both aimed properly.

Lastly, a dish eliminates most reflections. Believe it or not, your device can use those reflections to reconstruct the signal. This can reduce the reliability of your 5G connection.

Even the "dish" liked above has a log periodic feed.

A log-periodic antenna gives you good antenna gain over the entire range of 5G.

This is why you dont see true reflector dishes used for cellular.

They do use microwave dishes to talk between towers, though, especially in rural areas.

[mild whale]

Sure, looking at the XPOL-2-V2. You can see it states "...Is a full dual-polarized full LTE band antenna..."
So, in MIMO setups you use two antennas mounted at ±45° to match the towers polarization. (Yes, wave polarization is a thing). Each LPDA is linerally polarized along its elements, preserving the isolation between channels.

I think from here if you want me to go full maxwell's equations we should carry it elsewhere, but if you're curious I happily yap about my best friend James Clark Maxwell.

[velvet jolt]

Does anybody know about this? Our internet is using MPLS to a different location. I made a separate VLAN for guests. For NAT, I assume we would point towards the other location, but if we want it to be separate, do you need to change settings on the other location?

[opal pagoda]

mpls is just a service for L2 transit between sites, sometimes it is used to transit all trafic over to hq where central fw is, sometimes it is just s2s traffic
without knowing what is configured it is very hard to answer this

[dreamy sonnet]

Hmm theres a tower i can physically see, but not appear on map

[opal pagoda]

have you selected correct provider and 4g?
actual 5g SA towers are rare af

[dreamy sonnet]

I havent specified anything. Theres towers in green and towers in red. Show up as Macro type, LTE towers

[opal pagoda]

you need to select provider as it is not a given that that tower is for your provider

[dreamy sonnet]

I chose the 3 providers we have. None of them show the tower. From what ive heard, its a new tower i believe. I do believe its finished. I checked the coverage map of the most plausible owner of the tower and its stated the area has very good 5g coverage

Whats the cell stuff? What its supposed to cover or something?

[opal pagoda]

yes, those are the areas that are covered with a cell, if they overlap they serve to increse bandwitdh by utilising mimo, in this case it would be 2x2 mimo

[dreamy sonnet]

This cell goes right outside the house, following the road right outside.

[opal pagoda]

you can install cellmapper on your phone to improve accuracy in your area

it is a community mapping project

[dreamy sonnet]

These 2 are also right outside lol

Oh i can do that 🙂

Tower is i guess 10 km away.

[opal pagoda]

tnx mods

[dreamy sonnet]

@opal pagodaidk seems maybe easier to try starlink now lol. Hear both good and bad things about it

[opal pagoda]

try using 4g/5g router without any external antenna and see what you get

maybe isp has trail period that you can use

[dreamy sonnet]

I will tomorrow. I have 2 weeks trial. Received it yesterday 🙂 The 2 biggest ISP's apparently couldn't deliver in the beginning, but both state max strength 5G data around the area. One of them suddently could deliver but the other could not. Strange lol. The ISP i chose shows less strength for 5G, even though they use the biggest ISP's towers as well as their own. Should in that case be full strength too lol. Just a bunch of joke sites really

[opal pagoda]

in this 2 weeks try it in various positions in the house including outdoor in order to evaluate if outdoor antenna will be of any benafit

[mild whale]

draw attention to the uplink and downlink frequencies

[shell remnant]

@stuck grove @frosty stone yall both reacted to this image, ive goten told that its is a 2.5g ap a unkbown brand #networking message orignal message

[frosty stone]

That wasn't why we reacted

[shell remnant]

why did yall react

[open scroll]

Is this shot on a iPhone or smthn

[shell remnant]

shot on a low quality andriod 😭

[frosty stone]

We reacted because it's kinda weird to just randomly post photos of random APs you found in public

[opal pagoda]

Yep

[shell remnant]

help i didnt know

i just wasnted to show yall my spotings

and showing what i spot

[copper cedar]

Alr guys. I need your help. Does anyone have any experience with Windows Always On VPN and configuring Trusted Network Detection to not connect on a corporate network

[cunning lion]

I am going to assume that packet loss is why my internet is hitching a lot on trying to load anything. Instead of loading right away it takes a few seconds to do anything before things stop popping up on screen

[pastel monolith]

1-2% shouldn't be a huge deal can check chrome or other browser networking tab and see timings to get better idea of what it's spending time doing

Pihole as local DNS cache can help (browser and OS both typically have DNS caches as well though)

[copper cedar]

Holy just figured it out!!!

[obsidian pilot]

idk if this is the right place for it but I am looking to build a better NAS for plex and storage, I kinda want a rack mount case like the 45drives AV15 but without any included hardware and only around 150$ if anyone has any suggestions? I cant find anything that has a sata backplane like that where I can just drop drives in with no tools

[amber urchin]

Netapp DS4243 or DS4246 from ebay and an external SAS card. If you want to use SATA drives you need the interposers. You will not for SAS. If you want to use 10k or 15k drives you will need 4 PSUs, if not 2 PSUs is sufficient. Ensure that you have no open holes in the back from missing PSUs or I/O Modules otherwise the thing will scream like crazy.

I'm running a 9305-16E HBA with four 8436 to 8644 half meter cables to my DS2246 and DS4243 (with IOM6 for 6Gbps - tho not all 4243 play well with the upgrade).
You're also lookin at likely around $200 for shelf. Mine was $213 with tax loaded with PSUs, IOMs and the 24 drive bays. It also came with some interposers I wasn't expecting.

[obsidian pilot]

I should have specified only around 15 hard drives and atx lol

maybe someday on the "disk shelf"

ty tho!! im tryna put my i7 7700k in there on my atx board and a graphics card for video encode and captions

[amber urchin]

Trust me when I say, disk shelf now

Yes, you can manage to get a case that supports 16 drives. But how are you going to power those drives? Particularly if you want to use SSDs that use entirely 5V instead of 5V and 12V?

Even huge honkin 1600W PSUs only provide like 120W combined over 3.3 and 5 volt rails.

Although - with the 4U shelf, you'd need to get the 3.5 to 2.5 adapter per SSD and that adds up quite a lot. I had sixteen HDDs in an old Thermaltake case. I wanted to add some SSDs to use as a L2ARC only to find out that I be significantly over the limit on my 5V rail by adding the ten SSDs. That's when I kinda lost it and went on ebay to get an external HBA, the 2U and 4U shelf as well as the cables. Ironically, it did not cost all that much more than I spent on the case and new power supply since the 620W I was using wasn't enough for the 16 HDDs on their own.

[obsidian pilot]

hmmmmmmm

maybe I dont need that many drives

i could just do 6 with better density

[opal pagoda]

Jonsbo n4 or n5 then

[silent flax]

but he wants rackmount 🤷‍♂️

[opal pagoda]

do you already have a rack bought?

what is its depth?

[opal pagoda]

what is the idile power utilisation of those shelfs

[amber urchin]

I cannot say at this time as I do not have a meter.

If you check, I have seen it in youtube videos before.

[glass anvil]

I'm preparing to deploy OM4 fiber in my home.

[obsidian pilot]

I dont but I am going to get a full size one, about 7 ft tall and standard depth

[obsidian pilot]

yknow what I am just going to use my monster HP Proliant Dl580 G7 I have

put a gpu in it and should be off to the races

I wanted to use something a tad bit more modern and something that doesnt use 4 ancient processors but oh well lol

and plus then I have to use laptop hard drives buttttt I guess if I get a bunch of 2tb drives I can raid em together

[gleaming dome]

Paging relay :3

[pseudo blade]

Power usage might change your mind lol

[mild whale]

I would like to set up a thing where Tailscale is installed on the OS, and uses nordVPN as a VPN service.

Would proxmox be a good solution for this?

The goal is to use tailscale as an exit node, where the OS uses nordVPN.

[amber urchin]

initial thought would be a vm with tailscale and a vm with opnsense router using nordvpn, but being able to reach the tailscale and also not leak anything would require some fancy firewall rules.

[lone crane]

or you know mullvad

[amber urchin]

Mullvad is a solid vpn choice

[lone crane]

the way he is talking about sounds insane

at some point just get a VPS and pangolian

[mild whale]

Im aware of this, and I have it; just trying to find a use for the rest of my nordvpn sub lmao

[lone crane]

GL

[mild whale]

Also might learn something that way.

Is ok.

[glass anvil]

I would replace that. I have a DL360P G8 with 2 12-core Ivy Bridge CPUs. HPE requires subscriptions to use the integrated console and advanced management features. Dell and Lenovo are permanent licensure.

[opal pagoda]

Do you mean ilo?

[glass anvil]

Yep.

Plus the firmware date on that management card is going to be ANCIENT and may not even be compatible with modern browsers.

[twin pier]

There was a way to activate it without paying, I forgot how

[opal pagoda]

[full storm]

10G network cards are cheaper than gigabit network cards who'd have thought now i just need a bunch of SFP cables that work with these cards that i know nothing about because they're in a server that i haven't gotten yet then i can see if they're gonna be some proprietary bs cards that i need a special SFP male head thingy for or not xD

[stuck grove]

that's the real problem, SFP cables are quite a bit more expensive

though SFP cables are usually universal

unless you get a real asshole of a switch that's super picky

[silent flax]

https://www.aliexpress.com/item/1005006057769662.html but on other side pure SFP+ 8x10G switches are much, much cheaper than 8x10G RJ45 switches

[full storm]

yeah, I already have a 26 port gigabit switch and for now I'll only need 2 things to be 10g aka my pc and my nas SO i was thinking about just direct attaching it for now and getting a switch later

[full storm]

haha yeah

[lone crane]

i would 100% get that if i did not have like 10 NUCs

[silent flax]

get one of the 4x2.5 + 2x10 SFP+ switches for like $30. You can use the 2x10 for connecting the 10G links, and one of the 2.5 ports for the other switch. That way you don't need to deal with all the DHCP/IP crap

i mean direct link usually means you have to set static IPs, have to deal with correct routing etc. If you use one of those cheapo switches, it will all just work on it's own

[lone crane]

unmanaged switches just work

[silent flax]

i mean compared to direct link, it is less of an hassle to set up 10G link between two PCs

with direct link you have to configure networking, with switch on your network they just inherit the normal DHCP settings, and outside of one more hop it works the same way

[full storm]

all i'm hearing is you guys are giving me a reason to buy more gear

i could make use of a 10G switch for so many things ||i'm lying|| so i'll just get one xD

[nova glacier]

not if you use ipv6. Neighbor discovery protocol allows the link-local ipv6 addresses (fe80::/10) to be discovered and used without any configuration

[silent flax]

still, $30 for having just one network connection, while still using it to connect to the whole network, while at same time having a direct link is just worth it for the convenience. But that might be just me

[nova glacier]

They said "direct attaching it for now and getting a switch later", so it was always their plan to get one anyways. Direct attaching just isn't that much of a hassle for a temp solution if IPv6 is acceptable. Not that static configuring ipv4 is that much of a hassle either

[lone crane]

30$ for a dual 10gig and quad 2.5 gig aint half bad anyways

[obsidian pilot]

what does the cisco 4451 even do bro 😭 I got one from work for free and I have no idea what its used for

assuming it can be used as a firewall

[pseudo blade]

It's a router.

[obsidian pilot]

I have to reset everything lol they were going to just throw it in the recycle bin without resetting it

[pseudo blade]

It's a highly-modular router with a bunch of enterprise features, though some require special licensing for stupid reasons

[obsidian pilot]

mmm

bmw heated seat moment

[pseudo blade]

Yes it can do firewall stuff though Cisco would like you to buy a proper appliance

Yours is not equipped with any modules so you've got gigabit ethernet only, in RJ45 or SFP

[obsidian pilot]

womp womp

[pseudo blade]

TBH... it's not an especially sensible device in that configuration except to learn Cisco

[obsidian pilot]

might just rob the ssd out of it an sell it pfft

[pseudo blade]

My Cisco nerd coworker would love one but yeah, not very efficient

[obsidian pilot]

lmao if he pays shipping he can have it pfft

[pseudo blade]

That would likely be an expensive ask

Australia and all that

[obsidian pilot]

OOF

[pseudo blade]

Is that a G7 proliant below it?

[obsidian pilot]

yupppppp

[pseudo blade]

Probably a lot of CPU cores, if electricity is free to you

[obsidian pilot]

I am going to set up solar for literally just my homelab

[pseudo blade]

Not very fast ones but that's what a decade plus does to you

[obsidian pilot]

I used it for that folding at home thing during covid

[pseudo blade]

lol some of our customers still run hardware that old and aren't rushing to upgrade

Today's major case was a customer with > 10,000 2012 R2 VMs on relatively old hardware

They pay for ESUs. Why? How? Surely allocating engineers to upgrade stuff is much cheaper.

[obsidian pilot]

LOL

ok now on to figuring how to configure my cisco 2960-x to do full home ethernet

[pseudo blade]

That's like $60 million USD retail in ESUs this year. Perhaps they get a good volume discount but I doubt Microsoft makes it that cheap

Their fleet is 100% 2012 R2

[obsidian pilot]

Jesus christ

[pseudo blade]

In 2025

[obsidian pilot]

I will take that 60 mil from them and say here is linux glhf

[pseudo blade]

I suspect that if they were that tolerant of change they'd have done that

[obsidian pilot]

what do YOU MEAN

literally following documentation

[native kettle]

Had this issue and it fixed it self but now it is back and is still frustrating me. The problem is that I am loosing internet connection to my main pc. Now matter what I do. I have to tried different cables, network adapter, different ports and even a different router and switch. Something is pointing towards a windows problem or maybe a motherboard problem. I even tried a using a different ssd as a boot drive with no success. I hoping someone has some idea of what is going on before I resort to buying a motherboard off of eBay.

[obsidian pilot]

?

have you tried a new network card?

[native kettle]

Yes. I tried using a 5Gb usb network card. And cheap 1G usb network card.

[karmic marten]

typo. you put an m in switchport.

[obsidian pilot]

ignore that I tried without that lmao

figured it out

[karmic marten]

plus you're not in port mode

[obsidian pilot]

whar

[karmic marten]

you need to be in "int et <portnum>"

ohh

that's cisco?

[obsidian pilot]

yep

[karmic marten]

mybad then, you were in the interface. I'm used to Arista

Arista shows the interface name ur in

like this

[obsidian pilot]

ohhh

[karmic marten]

haha

so similar, yet so different

Are you learning for CCNA?

[obsidian pilot]

just for fun!

(its not fun)

[karmic marten]

ah

Good luck

[obsidian pilot]

;DDDD

[karmic marten]

Good to have cisco knowledge, though.. Many providers are switching to Arista, Juniper, or Mellanox

Cisco is just a powersucker

[obsidian pilot]

I wanted to really try and set up my whole house for gigabit ethernet lmao, and do ethernet runs everywhere

would love to set this thing up as a "dumb switch" where it just lets the router (eero pro6e) do dhcp and give out ips

[karmic marten]

Setting it out as a dumb switch is really easy

[obsidian pilot]

well im really dumb XD

[karmic marten]

:p

You basically have to disable routing on it. And enable all ports + put them in vlan 1 and assign an ip to vlan 1

(don't neccessarily need to assign an IP, only if you want a "half dumb" switch") - if you're doing L2, you shouldn't do this

[obsidian pilot]

should I just factory reset it from what ive done?

[obsidian pilot]

I want this thing full dumb, all 48 ports completely unmanaged lmao

[karmic marten]

so just the first part

[karmic marten]

If you want to. Not really neccessary. But cleaner that way

[opal pagoda]

Well you fucked up the syntax

[obsidian pilot]

ignore that

[opal pagoda]

Configure terminal
Interface range gi0/1-48
Switchport mode access vlan 10
No shutdown

[karmic marten]

and preferably set portfast

But there is a reason I didn't give the commands to him

or her*

[obsidian pilot]

:3

[opal pagoda]

Idk if there will be a upstream switch

[karmic marten]

doesn't really matter, does it? If it's just an L2 switch is all fine

which it would be

[obsidian pilot]

can I do that interface range command all in one shot?

[karmic marten]

Yes

[obsidian pilot]

because im getting a syntax error at gi0

[karmic marten]

that's why it has "range" in it

[karmic marten]

uh

does the switch have a gigabit ethernet port?

[obsidian pilot]

48 of them

[karmic marten]

are you 100% sure it's not 10/100?

show ip interface brief
pls

not in conf mode, just enable

[karmic marten]

ahh

[obsidian pilot]

WAIT

[karmic marten]

cisco fucking syntax

[obsidian pilot]

its 2 not 0

[karmic marten]

well

it is 2/0/x

You know why I say now that people started switching to other brands 😄

[obsidian pilot]

oh im feelin it now mr krabs

[karmic marten]

@opal pagoda come here, you go ahead and have a bit of the headache as well

[obsidian pilot]

errrr

[karmic marten]

you need vlan 1

and not like that

switchport mode access
switchport access vlan 1

[opal pagoda]

If portfast is enabled you may get fucked by bpduguard

[karmic marten]

that's why you disable bpd :p

[opal pagoda]

Define vlan 10

[karmic marten]

She needs a dumb switch

[obsidian pilot]

ok we might be goated now?

[karmic marten]

PnP

She needs vlan 1

[obsidian pilot]

I did vlan 1 :D

[karmic marten]

and then you need these

[obsidian pilot]

and no shutdown doessss what?

[twin pier]

isn't vlan 1 just untagged

[karmic marten]

it reverse shutdowns

[opal pagoda]

I always blackhole vlan 1

[karmic marten]

it starts the port.
autistic describing

[karmic marten]

fair.

no shutdown
spanning-tree portfast
spanning-tree bpduguard disable

[obsidian pilot]

done :D

[karmic marten]

You should have yourself now a fully dumb switch

hell, maybe even as dumb as the orange racoonman

[obsidian pilot]

idk its still a computer so by default its smarter than him

now i just write?

[karmic marten]

w mem

write should work too I think

[obsidian pilot]

LETS GO

I was concerned as to why my speed was so low only 250mbps instead of 600mbps, cat 5 cable I grabbed first

[karmic marten]

and then you realize how much power it sucks

[obsidian pilot]

gonna get power meters and stuff

370 watts isnt that bad

[opal pagoda]

Thats available poe power

[obsidian pilot]

oh

oh so like half

[karmic marten]

show environment power

is the command you check the usage with

[obsidian pilot]

ah yes tons of info

28 watts rn

[karmic marten]

ooh lmao

[obsidian pilot]

show power worked

[karmic marten]

hmm that's not that bad. Wait till u connect all the ports lulz

[obsidian pilot]

im probably not going to have more than 10 hooked up

[karmic marten]

28 watts is like mikrotik levels

Any suggestions for CCNA Courses?

[pseudo blade]

The Netacad ones?

I don't really know where you're starting from

Do you have network equipment knowledge? Knowledge of application protocols? Any previous experience?

[ebon sierra]

I have watched all of the network+ videos from Prof. Messer. I am also graduating this fall with a Computer Science BS with emphasis in Cybersecurity.

I am starting CCNA to help with the memorization of all the Net+ stuff while starting to learn Cisco, as I am hopefully getting a contract job while I finish up college (I have "interviewed" for it, but a Coke plant explosion set some things back)

I am leaning towards the Niel Diamond course (His website not Udemy) as it has videos, as well as quizzes for every section, and a lot of labs

The IT director I met with wanted me to start doing some of the CCNA stuff so I have a better understanding of the hardware that they use

Hello everyone! Any open source network monitoring tools that don't need SNMP or an agent install ?

The problem is that the systems me and my team are responsible for are extremely sensitive .
What I tried so far in terms of tools are : nagios ( huge fail because the open source version makes you hard "code" each host...I've got about 3000+ devices. screw that) and I also tried LibreNMS and Checkmk. Also fails.

Anyone got anything else I could try ?

[opal pagoda]

" that don't need SNMP"
wdym, you will have no device data or traps just ping

[coral marlin]

Not interested in stuff like : how much ram this process or that process or how much traffic that computer has. I'm more or less interested in having more of a "raw" oversight of the network with being notified about things like intermittent network disconnects at specific points in our 14 locations and more or less just check if certain critical computers are online or not.

[opal pagoda]

uptime kuma

[coral marlin]

can I boot this up separately in to a VM without docker ? kinda hate it xD

[opal pagoda]

all you need is node afaik

https://uptimekuma.org/install-uptime-kuma-linux/

[coral marlin]

oh I can boot this on to a windows server as well. Pog good to know. Gonna be more appealing to my older collegues that are not so familliar with linux hehe 😄

Would the topic of open source ticketing system also be apropriate here ? or do I need to go in to the #linux channel ?

[opal pagoda]

i am not familiar with any

I ugh .... powered through GLPI ......But they uhm ....pay-wall locked SSO....xDDDDDDDD

Like, I love all the features it has but bruh .....putting SSo behind a PayWall...No regard for security in the open source world ...

Doesn't even have an auto update feature xD like if you wanna update .....90% chance you'll break your setup kekw

According to a dev : the only way to auto update is through docker..bruh...lame

So i have had this issue with ethernet, it randomly disconnects, first it forced it to 100mbps and never disconnect again (i have 1gbps) but since installing newest LAN drivers it worked for a day and a half and it disconnected but keeps it at 1gbps so here are things ive tried:
Installing newest drivers
tried different ports on router
new router from ISP
new ethernet cable (yes its cat6)
Reset network
Turned off all power saving things in the settings
i just did a flush dns to see if that helps and if it doesn't i will try and get a usb 3 to ethernet adapter to see if its the physical port even tho i doubt it since it works for over a day.
if someone has any other options/solutions to this issue please tell me.

[opal pagoda]

L1 issue

if you have cable tester then test your cables

maybe look inside rj45 port to see if there are any bent pins

[pseudo karma]

I looked and no bend pins, i think my uncle has a cable tester so i will go pick it up somewhere this week

Might be a dumb question but i use it on the connector thats directly in the router right?

I have a cable that goes from router thru the wall to my room in a wall adapter and from there a cat6 cable to pc

[opal pagoda]

with cable tester test end to end connectivity

could also be that cable inside the wall is broken

[pseudo karma]

i tried with multiple cables from wall port to pc and all same problem, i doubt its that so if its a cable issue its def the cable in the wall

Maybe after all these years the cable in the connector got loose, so first ill try to cut it shorter and redo the connector, if the issue is still there i will have to run a new cable thru the wall

[pseudo karma]

got it, makes sense

@opal pagoda so the cable that runs from the router thru the wall is connected to a wall jack like this, how would i test it with the cable tester if i have to test it end to end, will i be able to plug a good ethernet cable in the wall jack and plug that in one end and it will show if something bad only on the side where the one that goes directly in the router is connected too?

[twin pier]

am i crazy or is that a phone jack

[pseudo karma]

idk i typed in wall jack ethernet and that came up 😂

but its something similar to that is my point

[twin pier]

oh i thought you meant that was yours

[pseudo karma]

there is no end to end connectors

[pseudo karma]

no mine looks something like this

so im confused on how i can test that with the cable tester if its end to end

do i plug a cable in that and THAT in the tester and it will only show a bad connection on the connector from the cable in the wall or?

[twin pier]

itll tell you if there's any bad connection anywhere between the two ends of the tester

[pseudo karma]

got it, thanks

[nova glacier]

test the patch cables on each side first. Once those are known-good you can test the in wall cabling (and the jacks)

[pseudo karma]

okay

[cunning lion]

cable on either end of the run basically. Aka each end of the tester in different rooms basically

[lone crane]

Look what I got

[opal pagoda]

o nice

be carefull not to fry transcievers tho

[opal pagoda]

how much $?

[lone crane]

0

[opal pagoda]

3d printed save icon slot

next, buy a fusion splicer

[lone crane]

If I manage to get a splicer for free somehow probs not gonna be possible but a man can dream I could almost start making custom fiber cables or some shit or do office fiber installs

[opal pagoda]

if you ever wonder how much does a 6kw CRAC costs

[opal pagoda]

making cables does not require a fusion splicer but it is more time intensive
you need connectors, fiber cleaver, fiber polishing tool and resin

with fusion splicer you almost always need a splice box with splice tray inside

[lone crane]

Ye

[pseudo karma]

i did it and the tester showed it had good connection

both the cable in the wall and my ethernet cable from wall to pc

[nova glacier]

wiggle the cable around each jack while it is testing. intermittent issues with connectors may not show up without some exacerbation.

[pseudo karma]

Alright, ill do that tomorrow after work, thanks fir the tip, when i picked up the tester earlier it did stop halfway and restarted , idk if thats something

[nova glacier]

what kind of tester? A disconnect certainly isn't a good sign

[pseudo karma]

One with the 8 lights

Really bad pic

But its just one that does the 8 lights

[nova glacier]

oh, just a continuity tester. That's all I have too, but those are a bit tougher to use to detect an intermittent issue. an advanced tester would've flagged a disconnect as a failure condition

[pseudo karma]

I see, this is all i have unfortunately

[nova glacier]

you can still observe a disconnect visually with it at least

[pseudo karma]

Yep i also have a tool for cutting and terminating connectors and the connectors themselves do maybe its smart to just cut a bit off and redo the connector

[nova glacier]

could be one of the keystones on the wallplates too. that would be my assumption, but yeah any of the connectors could be a culprit

[pseudo karma]

I could do both to be safe

[minor girder]

I'm having a bit of trouble accessing my nas... I've basically done a complete rewire of the whole house and fear I've done probably a noob mistake 😅

[minor girder]

Ok... so how do I make it not so 🤔

Is it the ip address of the router causing issues?. I've set dhcp to disable and put it in a hot-spot mode

[peak cloak]

If it's in ap mode the IP of the PC should be on the same subnet as the modem

In that case the modem is being a modem/router

And your wifi router is just an AP

[minor girder]

So the modem is what was given to us by our isp. Its crap so I connected a WiFi router to get better coverage and speed given its wired directly into it.

[peak cloak]

Another option is to wire everything to your router

[minor girder]

The pc currently is and the router is wired to the modem

[peak cloak]

Yes but not the nas

In theory if you put some static routing rules you can have the PC connect to the nas but it gets messy

[peak cloak]

And put ISP modem into passthrough mode if possible so it's just a modem and doesn't do any routing or NAT

[minor girder]

The nas is incremental backup storage so speed really isn't an issue. So currently the isp modem is doing all of the dhcp stuff,

Would setting a manual io address of the router to one similar to the modem, (192.168.0.21) work?

[peak cloak]

It's not about speed, it's about network topology

And no that wouldn't

Make sure DHCP is disabled on your wifi router
and instead of connecting to the WAN port, try to the LAN port instead.

What's the router model, it may have an access point mode

[minor girder]

Ok so I'm setting the modem to modem mode, was set to router mode

Got it
. Its a tp link ax1500

o that way

[pseudo karma]

I wiggled it around pretty rough and it didnt give a disconnect

I also checked the wall jack for any damaged or loose pins and no visual damage to be seen

[nova glacier]

around every connection? A LinkIQ or similar tester would be necessary to get a proper signal integrity test. Continuity testing doesn't tell you much about whether the system is capable of 1Gb vs 100Mb. Even the older CableIQ on the second hand market is still quite expensive though. It might be possible to trigger the issue by running iperf between two PCs on each side, as an alternative. Without something to trigger the issue it'll be hard to narrow down where in the system the actual issue is.

[pseudo karma]

Right, i wiggled it thru 5 full cycles of the tester and it didnt disconnect once, for the system its been running 1gbps for like 2-3 years without issue, its not a new pc just a new problem, i havent been on my pc since i tested so i cant say the issue is gone/better or anything

But it hasnt been capping it at 100mbps at all despite being on auto negotiation

[nova glacier]

also if you replace the keystones, go for the higher rated ones like 6a. Replacing the in-wall cabling might not be feasible, but you can still at least use keystones with improved signal loss characteristics. That should help give more headroom for the signal

[pseudo karma]

What i will prob do is tomorrow leave my pc running youtube autoplay while im at work and thru the night for a few days to see if it still disconnects at any time, havent been on my pc long enough since my final attempts to fix it to see if its still there and if it is, i can replace the wall jack since they are fairly cheap and if that doesnt work i might consider buying or borrowing or whatever one of those CableIQ things

[pseudo karma]

Thats fair, now that i think about it, the keystone has 2 ports but only 1 is wired i think so i could just swap it to the unused one

And see if the one im using rn is faulty

[nova glacier]

youtube isn't very heavy, even with it being bursty I doubt it'll ever reach more than 100Mbps. An issue in signal integrity will be triggered more reliably if you can run a bidirectional iperf test through it to another pc on the LAN, which will 100% the link constantly.

[pseudo karma]

Right but i dont think it needs that since before this issue also happened when i was just watching youtube and nothing else

So i dont think its traffic overload

[nova glacier]

A signal integrity issue causing the link to downgrade doesn't require the link to maxed out, but maxing the link out is the most reliable way to cause it to happen

[pseudo karma]

I think best plan is to first let my pc run 24/7 for a few days and see if it still disconnects and then see what i already tried and the remaining options because im anything but tech savy when it comes to this type of thing.

But at least i know more then before now

Also the fact its 12:30 am and im not even on my pc rn isnt helping

https://discord.com/channels/375436620578684930/1408215583635538092 perhaps some of the networking gurus here can help me, basically I have a supermicro server that I cant get to connect to the network at all, I'm a massive noob

[opal pagoda]

Ill take a look tomorrow

[mellow karma]

Does anyone know of a network adapter with both Wi-Fi and Bluetooth that supports Linux and Windows operating systems for an old PC?

[nova glacier]

What's the motherboard's model number? You may able to find it in msinfo32, but if not it's always printed on the motherboard somewhere

is a pcie slot and a usb header available? if so, you can get a an AX210. pcie 2.0 x1 (4Gbps) wouldn't be sufficient for the newer WiFi 7 (5.8Gbps) chipsets, but it can handle wifi 6e (2.4Gbps).
Something like this:

[subtle wing]

Anybody know of a 2.5gb poe switch that's managed, somewhat small and ideally fan less? I know im likely asking for a unicorn but

[opal pagoda]

how many ports, what is your budget

[pseudo karma]

@nova glacier so far 8 hours no disconnect at 1gbps on auto negotiation

[nova glacier]

If this is still just with a yt video, it could take a very long before rare conditions cause a downgrade. The cable will be active for less than 2-3% of that 8 hours. A possible interfering signal that causes the signal to go out of spec would have to hit while it's active. I hope this is a better explanation as to why maxing the cable out is necessary to test this in a reasonable amount of time.

[pseudo karma]

Fair but before i just left it on overnight with absolutely nothing playing and it disconnected after like 2 hours

But ill just see what happens

[nova glacier]

There's plenty of background tasks in windows that will use the network, but I am not at all implying the cable needs to be saturated for it to downgrade. Testing is just much faster by maximizing the chances.

[pseudo karma]

Good point but ive been working 8-12 hour shifts so setting all the stuff up i dont even have the slightest clue on what it is, i just dont feel like doing and ill just leave the pc on overnight
