No internet connection after Catalina upgrade
My MacBook PRO was on Mojave OS, and just by upgrading to Catalina, the internet stopped working.
The WIFI is able to connect but I cannot navigate (neither Safari nor Firefox). Other devices connected to the same network work perfectly and my machine worked fine just before the update to Catalina.
Something quite strange is that; even though I can't surf the internet, I can connect to my actual VPN (Endpoint Security), but even then I can't surf.
I have extensively reviewed the recommendations on this forum and have not been able to resolve the issue.
I tried to isolate the problem by creating a new administrator user and was able to connect and browse but erratically, the internet connection is lost from time to time, about 5 times a day.
Any suggestion?
