Since I upgraded my iMac to Catalina my WiFi connection constantly drops.

Why does my WiFi connection keep disappearing?


When I check network preferences I notice the network name book is empty, despite the "automatically join this network" box being selected.


I am using a VPN and have turned this off, but the issue remains.

iMac 27", 10.15
