Just bought a new 27” iMac- got everything migrated and worked great. Since it came preinstalled with Mojave, downloaded and installed Catalina. Now the computer will not list ANY wifi networks (including our home one) so no internet. Where we are there is usually quite a list. Tried restarting, removing and re-adding wifi as a network connection... any other ideas?
Solved! Just searched for the "Wireless Diagnostics" (command-space search) and ran that and it fixed itself. Don't know why it didn't come up as an option when there was no internet...

Restart your router.
No wifi networks
