Mediatek mt7921e network card not working

Question

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. I'm dual booting and Fastboot is disabled in the UEFI. Any idea how I can debug/fix this? Thank you.

Welcome to AskUbuntu. Are you dual-booting the notebook, or is it Ubuntu-only at this point? Have you disabled the "Fast Boot" option in your UEFI/BIOS? — matigo, May 11 '23 at 07:03
I'm dual booting and fastboot is disabled. I've edited the original post with more information — E-Kami, May 11 '23 at 07:05
My resources show that your adapter should be using the mt7922 driver, not mt7921e. Was the driver selected by the OS or was it installed manually? — matigo, May 11 '23 at 07:21
It may be as simple as sudo modprobe -r mt7921e to remove the existing driver, followed by sudo modprobe mt7922 to set the alternative. — matigo, May 11 '23 at 07:27
~ sudo modprobe mt7922 modprobe: FATAL: Module mt7922 not found in directory /lib/modules/5.19.0-41-generic — E-Kami, May 11 '23 at 07:28
For some reason now it's not working in Windows anymore either =/ — E-Kami, May 11 '23 at 08:06

Are you sure about your card-model driver and kernel version? I had a similar problems with my g14 zephyrus g14 which has mediatek mt7922 wifi/network card and solved it. Dualboot-ubuntu

Here is the steps and checklist

-> Ubuntu LTS (22.04.2) with Kernel 5.19.0-32-generic (at least 5.17.x required if it is not desired version you should update. -> lspci output was "network controller: MEDIATEK Corp. Device 0616" Then I copied drivers using linux-firmware thanks to https://askubuntu.com/a/1456986/1710221

sudo apt-install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/mediatek/{WIFI_MT7922_patch_mcu_1_1_hdr.bin,WIFI_RAM_CODE_MT7922_1.bin} /lib/firmware/mediatek

Then; Shutdown computer; Start pc/linux
