My Mac wouldn't list any wifi. I tried everything.
None of them worked !! I'm frustrated now.
I have attached the snapshots for further details.
MacBook Air 13″, macOS 12.0
Three things to try.
First, you may have done this already, select WiFi in the list on the left and then at the bottom, click the "-" to remove it. Reboot or actually shut down, then open Network preferences again and try adding WiFi again.
If that fails, in Network Preferences "Location" dropdown, select new location. Add a new one and give it a name. Then try Re-enabling and connecting to WiFi. You will need to re-enter any passwords required to connect.
The third thing if the above fail, create a new administrator account. Reboot, and log into the new account. See if you can get WiFi working doing that. This would indicate that somehow the network preferences in your account were corrupted if this step works.
