Computer does not hook up to internet
My computer was working fine and now is not able to "see" the internet. My cable modem and router are fine since my laptop is able to access the internet and get emails but not with my desktop which has the ethernet cable from the router directly.
I have used system restore to go back to yesterday (last time it worked fine) and still no dice.
What can I check to troubleshoot and find the culprit?
