MEDIATEK Corp. MT7922 802.11ax not working [SOLVED]

Hello ,
I have been trying to get this on-board wifi card working on my system for a few days. Oddly its available with the Arch live usb , but fails during normal boot process. I have applied the patch per a previous post but that didnt seem to work. Also tried reloading the module and restarting NetworkManager

root@figaro ~]# modprobe -r mt7921e
[root@figaro ~]# modprobe mt7921e
[root@figaro ~]#  systemctl restart NetworkManager bluetooth

I was able to resolve this issue with the correct patches , using the following url for instructions
https://github.com/morrownr/USB-WiFi/bl … dapters.md

[akrahn@figaro ~]$ ls -la /usr/lib/firmware/mediatek/
total 1644
drwxr-xr-x 2 root root    4096 Apr 20 18:45 .

After reboot, wifi and bluetooth are functioning correctly..

I had the same problem stumbled on this topic. Before messing around with these drivers manually first give the official firmware package a try: linux-firmware-mediatek.

(That missing firmware also prevented suspend in my case)

The firmware linux-firmware-mediatek-20250917-1-any fails with same symptoms (timeout during firmware load), for system76 pangolin 15.

Resolution is to pacman install the previous working 'linux-firmware-mediatek-20250808-1-any'.
