See if secure boot is on in UEFI/BIOS. If so, turn it off.

Try reloading the driver:

Code: Select all

 sudo modprobe -r ath9k && sudo modprobe ath9k 
If that's no help, maybe get a usb wifi adapter like Panda that works out of the box.

Do:

Code: Select all

 sudo ifconfig wlp3s0 up 
Then, let's see if you still have a driver:

Code: Select all

 lspci -nnk | grep -iA3 net

See which kernel you have now:

Code: Select all

 uname -r 
If you're still on 19.3, you should have 4.15.0-117 kernel. If not, get that kernel & see if wifi works then.

I don't see any changes, so just stay with the usb adapter which seems to works for you.
