So here's the situation, I can't connect to the internet. Wireless is working, other PC's in the home are working, I can ping the gateway, host names and IP addresses outside of the local network, LAN connection in the bottom right-hand corner is looking normal, ie there is no red cross or yellow triangle. Also, tried other cables and router ports. When I restart the PC, I get internet connectivity for about 2 minutes, then it's gone. Any suggestions please?
