I just moved to a new place and changed wifi network naming scheme and now I can't connect to rpi

[strange sierra]

I am able to connect to mainsailos.local via ethernet, but my previous wireless method of using http://192.168.1.141 no longer works

[strange sierra]

I changed th wpa stuff already using notepad but to no avail

Edited the 3 wpa files on my boot

I tried editing using text editor on Mac but was met with “no permission to edit this file”

[near owl]

Can you send that file, with your ssid and password censored?

[strange sierra]

does it matter if it is set to my 5g network?

google shows that my 3b+ supports 5ghz

i have a 2.4gz network too but i would rather have it connected to the 5ghz so i dont have to keep switching just to see print progress

i put the exact same wifi name and password in these 3 files

[near owl]

That is maybe the error...The file has to be named wpa_supplicant.conf and not mainsailos-wpa_supplicant.txt

[strange sierra]

all 3 or just the first one?

2 of them got funny name

[near owl]

Only one. The others doesn't matter at all

[strange sierra]

okay ill try it

[strange sierra]

wait i just remembered that my miansail os is pretty outdated

but ill try this anyway

[near owl]

I just checked and it should be the same, even for an outdated mainsailos/raspberry pi os

[strange sierra]

ping: cannot resolve mainsailos.local: Unknown host

[near owl]

Can you check your router, to see if it's there?

[strange sierra]

trying but my dad forgot the password so i cant log in to the router

ill update when i get access

[strange sierra]

I can’t tell

I read the list of devices but can’t tell which ip is the pi

I know the ip of the pi via Ethernet

But idk if it’s the same if it’s on WiFi

Is there a way for me to check the pi’s IP address by connecting a monitor and keyboard?

[near owl]

Yes, with ip addr

[strange sierra]

I have an issue now

I forgot my mainsail password

I tried pi but that didn’t work

I tried all my passwords to no avail

[near owl]

Forgetting the username and password is the worst thing. But there are ways around it iirc. But you would have to search for it on your own

[strange sierra]

It says here “started WPA Supplicant”

[near owl]

Then it most likely started and you just need to find the correct username and password

Or if you don't need your history, you could just backup your config files & mainsail settings and reflash

[strange sierra]

I’m able to get into mainsailos.local if connected via Ethernet

Without it needing a password and whatnot

What’s the default password?

Cause I think it might be set to default

But I don’t remember reading anything about it when I last flashed

[near owl]

With ssh?

[strange sierra]

Nop. Via web

Well I haven’t tried ssh

[near owl]

Default password should be raspberry

[near owl]

Web doesn't have a login....

[strange sierra]

Yeah biscuits

Not set to default

I’ll try ssh

[near owl]

ssh is the same basically

Just a remote shell instead of a local one

[strange sierra]

Yeah can’t ssh to mainsailos.local

Wrong password

“Permission denied (publickey, password)

[near owl]

Did you mabye setup a ssh key?

[strange sierra]

Probably but I don’t remember

Could’ve sworn I just used raspberry

Since I was too lazy to set one

[near owl]

pi is default user and raspberry is the default password

[strange sierra]

Yeah no go

Is there a way for me to change it via boot sd card?

[near owl]

☝️

[strange sierra]

Alright. I’ll try stuff

[strange sierra]

How do I do this

Do I just download my printer.cfg and stuff

[near owl]

Yes, just download all the configs. For mainsail you have to click on the settings button top right. There you will find the mainsail settings in moonraker db entry

mainsail.cfg is the only config, you don't need to download. That one is always the same

[strange sierra]

Ah okay

For the moonraker DB, I selected all the boxes except for webcams. Does that include my printer.cfg or do I still have to download that from the config files

[near owl]

You still have to download that

I don't know if you already reflashed, but you could also do a backup of the whole sdcard first

Just to be sure, that you don't loose anything important

[strange sierra]

The last time I reflashed was before I re-setup mainsail like 2 years ago

Hmm there’s a 32 bit and a 64 bit option now for flashing mainsailos via rpi imager

Which do I pick?

[near owl]

Doesn't matter. I recommend the 32 bit version, as the 64 bit version isn't really needed

[strange sierra]

Alright thanks

[strange sierra]

I’m confused

Now it’s not even working even via Ethernet

Okay so I got connected cause I apparently changed the name from mainsail.local to Raspberrypi.local

But that’s only via lan

Manually set the ssid and password via raspi config

[strange sierra]

I connected the raspberrypi to the router via Ethernet cable and it showed up then. But it’s not connecting to the WiFi so far

[near owl]

@pseudo tulip sry for the ping, but I guess you have a lot more experience with the wifi thing of SBCs
Wifi won't connect, but ethernet works. WPA conf and raspi-config got already tried.

[strange sierra]

That option isn’t viable for me due to the lack of Ethernet in my building as of now

It only works now cause the rpi is far from the printer

But once it’s connected there’s no way

[strange sierra]

I feel like they’re the one that helped me the first time this happened. But now I’m running into even more problems after problems

Yup I restarted it without the Ethernet plugged in and left it on for like an hour and no luck. I plugged in the Ethernet without turning it off and it connected within 30 seconds

[pseudo tulip]

Sorry, didnt notice the ping. Lrt me read to it first.

[strange sierra]

It’s alright. While you’re reading that I’m gonna put an option. Usb WiFi dongle

Tho I would prefer that to be a last resort since I’m trying to save as much as I can for a better pc

[pseudo tulip]

So, I only can guess here, do you use the exact same SSID's for 2.4 and 5ghz? This is often an issue with raspberry pis, also using WPA3 for encryption sometimes leads to issues.

[strange sierra]

Nope using different ssid’s

Well, different names

Tho my dad says im able to connect to any device even if im using the 5g while it’s on a 2.4g

Also I learned that I’m using the rpi 3B not the 3B+

So there’s no 5g built in

But yeah, I think it’s WPA3

[pseudo tulip]

For a quick test I would suggest, open an Hotspot with your mobile device, use simple ssid and password for the hostpot, normaly in Android you can see which IP the rpi then gets assigned. Try to connect via its IP from your mobile that gives Hotspot.

[strange sierra]

And if it connects then it’s an issue with WPA3?

[pseudo tulip]

If that works, you have to change settings in your router.

[strange sierra]

Found a Reddit thread from 2021 that says no rpi supports WPA3

[pseudo tulip]

Probably, could be a combination of. Also ensure there is no 'MAC filter' enabled inside routers firmware

[strange sierra]

Okay that’s odd. My wpa_supplicant.conf file completely disappeared

[pseudo tulip]

Then it has accepted your setup. This behavior is intended. Because there are no read limitations on FAT32 partitions and your password is stored in clear text. So, it sets it up and deletes the file if setup was succesful..

A template is inside WiFi-Readme.txt in boot partition. Just copy and paste the according blocks to a new file

[strange sierra]

hmm my iphone isnt showing any devices being connected

[pseudo tulip]

Then there might be an option you setup NetworkManager by using raspi-config or you Wifi module died.

Try to flash a standard, raspberry pios. If it works there you did something that messed up your mainsailos, this is hard to recover if you havent access to it

[strange sierra]

alright. im trying this now

[pseudo tulip]

Ofc on another SDcard

[strange sierra]

ah i already did a fresh install on this sd card

so i dont really have much to lose anymore

man i love KM switches when using a single keyboard

[strange sierra]

Trying to flash the default rpi os. I’ll update tomorrow or something

[strange sierra]

Okay that’s weird. So for starters, we have 2 routers. 1 being the one the internet provider gave us, then the second one which has stronger range and speeds which is connected to the first router.

The one it’s connected to is router 1

The one below it is our stronger router

And it won’t let me connect to it

But I can ping google.com when connected to router 1, albeit with high ping

It takes pretty long to load but I’m able to go on google images so the WiFi module definitely works

[strange sierra]

Solved. It really was just a problem with WPA3

downgraded to WPA2 and it works

[near owl]

Then please close this post

[strange sierra]

…idk how

I’m on mobile if that makes a difference
