The computer is a year old, it’s running Win7 SP1 64bit and the connection to the internet has always worked until now. For the last few days I’ve been unable to connect. On going into change adaptor settings I find that the properties tab for Internet Protocol Version 4 is greyed out. IP6 appears to be available but it tells me that I need to install a network adaptor. To the best of my knowledge I have never used IP6. I’ve uninstalled and reinstalled the network adaptor, I’ve disabled and re-enabled it. I’ve run cmd.exe as an administrator and I’ve tried:- netsh interface ipv4 install netsh interface ipv4 reset netsh winsock reset ipconfig /flushdns None of these have enabled IP4, it’s properties are still greyed out and I’m at a loss to know what to try next. Any constructive help would be greatly appreciated.
