No Internet Connectivity

Here's a very strange problem!

I have a dual boot desktop PC x86 machine running both w7 and win xp. I have a realtek RTL8168D GBE network adapter and a wireless adapter.

Until now, it has worked perfectly but now it won't connect to the Internet either using W7 or Win XP.

The wireless network is working fine - other machines are using it fine.
The PC is seeing the wireless network with Good signal strength.
There are no red or yellow flags against the realtek adapter in Devices.

I have tried uninstalling the realtek adapter and rebooting and it still doesn't work.

I have unisntalled the realtek drivers and d/l'd new ones from Realtek and then it connects to the Internet but only once - it doesn't do it again!

I have tried disabling the firewall and my virus protection but it doesn't make any difference.

Any suggestions gratefully received!
