Wifi doesn't work on arch

EkaSaffronGaruda · 2022-03-18 05:35:18

Hi, I recently switched to arch from garuda. I have a issue with wifi not connecting now. I tried hard enough to look for this issue on the internet, I tried to boot into live arch iso and connecting to my wifi using iwctl (results in "Operation failed"), even asked a few friends, no profit. Whereas when I just boot into live garuda, wifi works just fine.

-Technical details-
Host: Arch Linux x86_64
Kernel: 5.16.14-zen1-1-zen
CPU: Intel Pentium G4400 (2) @ 3.300GHz

lsmod: https://bin.garudalinux.org/?8b71736388 … zs1rMwKnYE
lspci: https://bin.garudalinux.org/?c4b65550e0 … kj4piZZ9Je

Wifi adapter: Realtek 802.11n WLAN Adapter
Wifi device: JioFi3

-The issue with my wifi-
Most of the time, my wifi device isn't even spotted when I see on NetworkManager, I then unplug and plug in my adapter, and that at a rare case spots my device and I try to connect, sometimes connects and sometimes just fails after a few seconds and the device is again gone from the list. Another thing I noticed is that, when nm detects my device, nm-applet shows that my device range is too far away ( https://i.imgur.com/o1V42nQ.png ), even though my device is kept right next to my desk.

What exactly am I doing wrong? Help would be highly appreciated!

There's neither a wifi controller nor an unassigned device in the lspci and "unplug and plug in my adapter" sounds like it's USB connected.
"Realtek 802.11n WLAN Adapter" is meaningless and so is the wifi router you're probably trying to connect to.

Please post the output of "lsusb" and a complete system journal "sudo journalctl -b"

You do connect to the AP, though?

Yeah as I mentioned it connects sometimes, although with poor network connection.

And I just added these lines

[device]
wifi.scan-rand-mac-address=no

to /etc/NetworkManager/NetworkManager.conf and restarted the NetworkManager service. Didn't help

I would boot the machine from a garuda live medium and compare the WiFi situation (driver, firmware) to arch.

I am a newbie so I am a bit confused so sorry about that.

Unsurprisingly they're using the same modules.
Post the journal from the garuda system - and try the vanilla and/or LTS kernel on arch instead of the zen one…

EkaSaffronGaruda · 2022-03-18 16:49:14

Is that necessary, I was using zen kernel too on garuda

seth · 2022-03-18 17:04:47

Posting the journal is is necessary for sure and testing a different kernel always a good idea to isolate the cause …

EkaSaffronGaruda · 2022-03-20 15:12:56

The issue is no more, I don't know what was causing the issue but, now I can connect to my wifi and use the internet with no trouble. Appreciate your time, thanks a lot!

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
