Internet not working after upgrade to Catalina

Hello

A friend upgraded her Macbook Pro to Catalina 2 days back and since then internet is not working at all. Everything was OK till the moment the upgrade was initiated. Any pointers on where to troubleshoot / fix would be really helpful.


Thanks

Please double check that you are wirelessly connected to the router you expect. I know that sounds obvious, but humour me.


If you are, then a useful set of steps is to check the situation after each of these. If the issue is resolved stop at that point:


  • Turn WiFi off and then on
  • Reboot normally
  • Reboot into Safe Mode (don't forget to return to normal after your check)
  • Reboot your router


Please come back and report results

We need a better definition of "internet is not working" because the internet is working.


How does the Mac connect to the outside world, wireless, cable, what?


Is the device that connects to the outside world switched on? Can anything else connect to the outside world through it?
