Hi Lisi

I would start with a ifconfig on each machine then compare the setting of the
two working with one non working to see if anything looks different (apart
from the IP address).

Swap the lead on the faulty PC with one of the working ones and recheck
connectivity.

On the router try moving the non working PC to another port prefably one of
the working ones.

Do you have wireshark installed? try starting that and then try connecting to
the internet and see what wireshark says

What make and model router did you buy??

Sorry if the first couple sound like telling you how to suck eggs but start
simple and work up (maybe I should remember that :o )
