I have 2 PC's and 1 Laptop all running Windows XP, connected to the internet through a 5 port SafeCom ADSL modem/router (all wired connections). Up until recently the network has been running perfectly, with no problems at all.

The other day, we had a had a power cut and ever since one of the PC's has been unable to connect to the internet. This PC was the only one that was on at the time, so I'm wondering whether this would be the problem, although the computer can connect to the rest of the network fine. I have tried setting up the network again on all of the computers but with no change to the situation.

Thanks in advance.
