Updated xubuntu to 19.10 which killed wifi. I do have the correct driver, I think, installed.
In Terminal the following output shows after trying the "dkms install rtl8814au/4.3.21" command.
Module rtl8814au/4.3.21 already installed on kernel 5.3.0-19-generic/x86_64
I can run update 19.10 with kernel 22.214.171.124 and it works fine.
What would you suggest I try next.
