lost internet after upgrade solved
I upgraded from 8.1 to 10 and lost LAN, so could not connect to internet. Troubleshooter advised a possible driver problem with the network card, however the Realtek GBT family card showed up as working in device manager. Researching Internet came up with no solution. I rolled back to 8.1, found updated drivers for the network card, installed them, and upgraded again. Still the same problem. A friend upgrading from 7 had the same problem and with the same network card, and wireless. I realised we both had PrivateFirewall installed, and as soon as I uninistalled it, Internet was working again. Same with his. Installed PrivateFirewall again, and everything good. Apologies if this has been covered elsewhere but I could find nothing, and hope this helps others.
