I just installed Ubuntu 22.04 desktop on my Zephyrus Duo 16 GX650PY but I can't get my Wifi card to work.

I tried to look it up and it seems the driver for this network card started having issues from kernel 5.16 onwards and people said a hard reboot was the only solution but it never worked in my case.
Any idea how I can debug/fix this? Thank you.

E-Kami,

The Mediatek mt7921e is problematic with many distros.

It is likely that a 5.18 kernel is required to permanently rectify this problem, but you may be able to do a temporary fix:

I have seen countless problems listed in many distro forums about mediatek Cards. If it were me I would buy a usb dongle known to work with Linux. Panda makes several but there are others. Stay away from realtek if possible and mediatek. Intel. chips work well.
