[HELP] WLAN device not detected!

Hello,
after migrating from Arch to Artix my WLAN device can't be detected anymore!
I have tried to reinstall linux-firmware multiple times, but no success.
The Kernel I am using is linux-zen.
Any ideas? I appreciate every help.

my lspci output (my mediatek device should be detected):

Welcome to Artix,

I am not an expert.
Depending on the mediatek device you are using, I have seen two AUR packages that you might be interested in :
Code: [Select]
$ yay mt7610u
3 aur/mt7610u_wifi_sta-git 1-1 (+0 0.00) 
    Kernel module for MediaTek MT7610U chipset featured in TP-Link Archer T2U and T2UH, TP-Link TL-WDN5200, ASUS USB-AC50, ASUS USB-AC51, Comcast Xfinity KXW02AAA, D-Link DWA-171 rev B1 and more

Code: [Select]
$ yay RT2860
1 aur/rt5592sta_linux_patched-dkms 2.6.0.0-7 (+3 0.00) 
    DKMS module which contains linux device driver for the Ralink RT2860 ABGN WLAN Card. It's based on halou89's rt5592sta_linux_patched package.
==> Paquets à installer (ex. 1 2 3, 1-3 or ^4)

This is not my first Artix installation/migration, but still thanks!

My point is that my wlan device worked just fine on Arch, which is really mysterious why it suddenly doesn't.

I guess I need to reinstall my Artix from ground zero which I wanted to avoid...

Quick Update: I have booted into the live USB for artix with openrc and it seems to have the same issue:

Every network device except from my wlan-device from my laptop is detected.

This means the Kernel or the Migration process in general was OK, but something is broken with current firmware...

Run
Code: [Select]
sudo dmesg | grep firmware
Hopefully there will a message identifying the missing firmware.

PS: I am using a plug and play wifi adapter to post this stuff. My Laptops's WLAN device still does not work.

OK no errors.
Not sure if that loaded firmware is the laptop or the adaptor wifi device?

Without the adaptor plugged in what's the output of
Code: [Select]
ip link show

Also reboot and post the whole of the dmesg output if you don't mind.

Whatever it was it was, it must have been connected to openrc, because I just made a fresh install with dinit and my WLAN device works flawlessly as before.

Since this issue isn't resolved I'll leave this topic open, so someone smarter than me can figure out what broke
my support.


My network device was from Mediatek, but I couldn't figure out which exact model.

My laptop is "ROG FLOW X13 (2022)" from Asus.
