I've been using this laptop for over a year now, with Ubuntu 20.04 installed. The wifi card is Wi-Fi 6 AX200. Since last week's ubuntu update (I regularly run sudo apt update), the WiFi wouldn't connect,keeps asking for password even if I put the correct password. However, if I boot in recovery mode, repair the packages and reboot, the wifi issue is solved, but only for that boot. In the next boot the issue comes back and I have to keep repeating the recovery mode step, however in this mode as expected multiple things are disabled (especially X and so I can't alter the screen brightness which is killing my eyes T_T). Please help figure out the issue with wifi.
There was also some message from snap before the incident, which I can't recollect, but I suspect that could be the issue. I can connect via LAN in normal boot though.

EDIT:
I see multiple similar complaints in last few days. Links:
No network after latest update: Ubuntu 22.04
Ubuntu 22.04 - just lost internet access?
Generic 22.04 kernel won't auto update
No network after latest update: Ubuntu 22.04
network completely disconfigured after seemingly normal boot
Ubuntu 22.04 only boot normally via recovery mode
Plus a follow up question on getting the correct kernel:
How to copy the kernel available in live usb to the system ubuntu installation?
