Mojave 10.4.3 WiFi problems I updated to Mojave 10.14.3 last weekend at home. When I brought my MacBook Pro into the office Monday morning it showed it was connected to my office network, but there was no connection. I restarted the MacBook and it connected flawlessly. When I brought it home that night it said it was connected to my home network but it wasn't. Restarted and connected fine. Four days later it's still doing this every time I switch networks. Not a huge deal, but kind of a pain. Any suggestions?
You can try to remove the network interface in "System Preferences > Network", select the network that isn't working, then press the "-" button.



And then add it back again by pressing the "+" and selecting "Wi-Fi" and naming it "Wi-Fi".
