Windows 7 - network connection OK but no internet access
I have a strange problem.
I have a Windows 7 Professional desktop PC that is set to use DHCP.
The desktop gets an IP address, gateway address & DNS server from the local router. I can ping the router and other devices on the local network can ping this desktop but there is no internet access (can't ping an external FQDN). In this case the ping returns "destination unreachable". In the task bar I see the network name but with the "no internet access" label.
I have tried both Internet Explorer and Chrome. There is no proxy server in use. I have turned off the anti-virus (AVG) and windows firewall but with the same result.
The network card is a Realtek PCIe GBE Family controller. I have checked in Device Manager and there are no conflicts.
