ATH9K - I cant get wifi connected after clean install of Ubuntu 18.

[prototempus]

Hello all, thanks for your help.

I've been trying in vain to get Wifi working on my server. It uses ATH9K and can scan okay but I can't seem to get it connected. I had it working before when I removed it from /etc/interfaces and used nmtui, but can do it with netplan.

I've tried all different setups in my netplan config and nothing seems to get it working. I'm new-ish to Ubuntu so maybe there is just something I am not seeing.

Here is the results of wireless-info script:
