Running Parallels 12.0.2 Windows 10 and using mainly Office 2010 programs. Since this morning when I think I tried to update Parallels I seem to have lost Firefox internet connection. "Firefox can't find the server at www.facebook.com" (and all the other ones too). Similar report from Explorer. Outlook 2010 fails to find my emails. I have re-instaled Parallels - but no change to the Windows online connection I have run Windows Network Diagnostics - says that the Ethernet cable is not connected - though I have now got Wi-Fi running. Safari runs OK on the Apple side My iPad and iPhone are connected via Wi-Fi.
