On Ubuntu 20.04 - I installed Easy Tether light (no-root) to do USB tethering using my android phone's cellular connection to get wifi on my computer. I use the instructions here to down load a deb file which I executed.
At the command line I entered this code as instructed.
systemctl restart systemd-networkd
This was successful in using my phone to get wifi. Now that the phone is disconnected I cannot connect to my home wifi network. In setting - wifi I see a message 'No WI-FI Adapter Found.
How do I get WiFi running again on my computer?
And here is the output as requested below in the comments.
