Ok, I finally had time to attempt a fix for 19.10 with 5.3 kernel. Secure Boot needs to be disabled so check
If it is not installed or says Secure Boot disabled thenCode:mokutil --sb-state
RebootCode:sudo apt install git dkms git clone https://github.com/jeremyb31/ath-5.3.git sudo dkms add ath-5.3 sudo dkms install ath-5.3/1
If it fails and you have no wifi, reverse with
Code:sudo dkms remove ath-5.3/1 --all
