The current kernel version (5.15.0) has disabled my PC wifi adapter (Qualcomm Atheros QCA9565) as well as the Bluetooth. I can boot up on a USB live version of Mint-Mate and the adapter is detected and works as advertised.

There is a older 5.4.0 kernel installed but if I attempt to boot on it I get an immediate kernel panic. I have recently upgraded to Ubuntu 22.04 (Beta), so there's no going back from there.

My question is, since my wifi is broken in 22.04 is there any way to know if my adapter module will be restored in the future? Because, if it is not I will be replacing Ubuntu 22.04 with another option. I'd prefer to not do that but I may not have a choice.

After following the recommended steps from @waltinator and others I discovered that the driver/module ath9k was not being loaded.

I could enter modprobe ath9k and the adapter would immediately become available. The fix was not persistent though, even after adding an entry to /etc/modules.

I then discovered that the module was blocked from loading in /etc/modprobe.d/blacklist.conf. A comment-out of that entry and the adapter is back to normal.
