My mt7921e kernel module for the MediaTek MT7921 wifi card will (seemingly) randomly, fail. This can happen from anywhere from just after login, or several hours after login. after that, I cannot shut down / reboot properly since systemd just keeps waiting for NetworkManager and wpa_supplicant to stop (which it wont).
After rebooting, the wifi card isn’t even recognised as a device in lspci. Only the ethernet controller remains. lsmod | grep mt7921 also does not output anything either.
After another reboot, Usually it repeats this cycle again. However sometimes, the device keeps not getting recognised by the system so i have to reboot (properly this time) again.
I have a Asus TUF Gaming F15 laptop.
