Easy Tether light (no root Andorid app) disconnected wifi when not tethering

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.

lspci -knn | grep Net -A3
0000:00:14.3 Network controller [0280]: Intel Corporation Device [8086:a0f0] (rev 20)
Subsystem: Intel Corporation Device [8086:0074]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

Solution 1:

TL;DR - Turn on the WiFi

The installation/use of the software mentioned in the question shouldn't interfere with the WiFi. It, however, turn off the WiFi in order to use the tethered connection.

The WiFi device is still being properly recognized and the kernel driver modules are installed and loaded. Turning it on again is all that was needed.
