What router is this?

echo talon
#

good question, it's a tp link of some sort

#

one sec though

#

#

it's just a default one from my isp so nothing crazy, but it's doing the job for now

echo talon
#

yeah, so i found the list of DCHP leases and where to add them

#

but the problem is i have a bunch of wifi devices (we got shelly switches in our place), the tv, phones, computers, now i'm playing with esp devices

#

some things i want to have a DCHP lease on it (like my esp devices) but the router doesn't have a way to show all devices that are connected to the network

#

for example, refreshing the router page that has the list of devices will change what devices are available

yeah, i was going to give that a shot - it sounds like it'll be good

drifting girder
echo talon
#

so according to my router, there's only 17 devices connected

#

which is wrong because we have like 15 shelly relays that are all connected

#

and as far as i can tell, if i go into the advanced tab there's not a place of connected devices and their ip address

drifting girder
#

If you click Advanced can you see more?

#

Unfortunately I couldn't find an emulator for your specific device to check myself.

#

It's also not evident how or when it updates this list or where the data comes from.

echo talon
#

i've scoured through advanced time and time again and i can't find any list

drifting girder
#

Assuming all the devices use DHCP the router should know about them as it has to keep a leases list in memory or on disk but the software might be 💩.

echo talon
#

which is also in the advanced section

echo talon
#

i think when they're set as static from the device they don't tend to show up in the router options, although sometimes they still do which is super confusing

drifting girder
#

That could explain it then. There's two ways to set a static ip. You can set it on the device but the router knowns nothing about that so if it's within the DHCP range you can get ip conflicts. Bad idea. You also can't resolve the hostname through the router. The other choice is to let the router assign a ip but reserve the device's MAC so it always gets the same one. Better.
I rarely use static ips but if I do, such as for my proxmox servers, I assign them outside the DHCP range on the server itself but also reserve it in the router's DHCP list so I can resolve the name.

You could switch your devices over to DHCP.

echo talon
#

yeah, i was going to at some point

#

it's mainly just the shellys i think at this point

#

which is annoying when there's so many of them

drifting girder
#

It's usually not really important for a switch or socket to have the same ip. You've got DNS and they communicate "indirectly" via MQTT, I guess?

echo talon
#

yeah, that's true

#

also random question you may know the answer to - if i were to change my router's ssid, would having everything have DCHP mean i don't have to reconnect everything to my router?

drifting girder
#

No you still have to change the SSID in all the devices.

echo talon
#

ach, i was worried about that

#

well yeah, i'll stick to the DCHP changes when i've got a minute then

drifting girder
#

You can run nmap (Zenmap GUI) on your PC as well btw. For mobile there's apps like Fing and Network Analyzer that can scan your network

echo talon
#

ah, on pc it might be a winner then!

thanks so much!
