thanks Spike. Sorry for the delay but I am helping my dad round at his house so we have only just tried it.
There was no yellow mark against the adapter in device manager, so we went on to the next stage which was ipconfig, however, this does not seem to do anything. Whenever we type ipconfig followed by any command it only says 'Windows IP Configuration', there is no additional information or actions being carried out. This was the same for /release /flushdns and /renew.
Again when I look at the device in network connections it says connected but there is no IP info and we still get the original message about TCP/IP when trying to repair.
Any further suggestions would be gratefully received
