I am running windows XP and have my computer hooked up to a router which connects to the internet for me. The laptop that I'm typing this from works on the router as well as my PS2. I keep getting this same problem on my computer that says network cable unplugged but it is not. This all happened all of a sudden. It also happened to me one other time and I fixed it by completely reinstalling windows. I'm trying to avoid this. I know that it is a problem with windows, because I've tried installing 3 different hetwork cards and have the same problem with each. Can you please give me a suggestion of what I can do.
