As you can see my AR9485 Wireless Network Adapter is there in the list but when I go to the wifi section, it says no adapter found. It was working just fine on ubuntu 21.04 but after upgrade Ican't get it back to work again!

Also, I have windows 10 running as dual boot. can this be the problem?

Here is the result of modprobe ath9k

modprobe: ERROR: could not insert 'ath9k': Invalid argument

Here is the result of grep ath9k /etc/modprobe.d/*

/etc/modprobe.d/ath9k.conf:options ath9k nohwcrypt=1

And here is the result of sudo dmesg | grep ath::
