WiFi Won't Connect

I have Ubuntu 20.0.0 on the VIM3. I can see my WiFi network, but it seems to always fail authentication. I have a different Linux computer with the same WiFi settings, and it connects with no issues.

Is there something I have to do to connect to my WiFi network?

@LydiaJ Do you have a wifi antenna connected?

Maybe you can try to use the command line to connect to wifi, and then log the information printed out, maybe you can see where the problem is.
