MBA Retina 2018 1.6ghz
After upgrading to Catalina my MBA can no longer "see" wifi networks when it scans for them. BUT, I have found a very strange workaround. That is, by first going to "create network" and setting up an adhoc network through the MBA, suddenly all of the WiFi networks appear when I scan for them.
I'd like to avoid this workaround, however, as it needs to be performed every time the laptop awakes from sleep.
Thanks for your help!!!!
