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?

  • When it's in its "connected but not really" state, does the Network System Preferences page show anything awry. When everything is good it should say something like "Connected - Wi-Fi is connected to <network name> and has the IP address <ip address>.", with a green dot in the sidebar list. – Ezekiel Elin Feb 21 at 17:28
  • Use Locations. The linked answer specifically address proxy settings, but it applies here as well. – Allan Feb 21 at 20:07
  • @EzekielElin yeah the preference page shows the green dot and says wifi is connected. – user783154 Feb 21 at 21:03
  • @Allan I'll try defining two different locations and see if that works. Thanks to you both. – user783154 Feb 21 at 21:04
  • I'm still experiencing this problem. I tried creating separate locations for home and office. Still having to restart the macbook every time a come into the office for it to actually connect, and about half the time I try to connect at home. Switching the location does not help. Any other ideas out there? – user783154 Apr 1 at 16:41

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".
