Ok I recently booted up a new windows 7 pc which I tried to connect to my sky router it worked, for 2 hours I browsed the web, downloaded files, you name it it was working, didn't drop out once. turned it off then later on again nada, I ran ipconfig in dos and got this back (see attached) what the hell does that mean, theres no dhcp assigned values, no default gateway listed, no ip address nothing at all its all blank.
