First of all, my internet connection was working great just before I formatted and reinstalled Windows (same version). After the Windows reinstall, I proceeded to load all my device drivers, etc. It was when I plugged my Modem into my computer (via eithernet cable) I realized I had no connection. I looked at my local area connection, and noticed it said "Limited or No Connectivity". I proceded to power cycle the modem, and after that didn't fix the problem, went ahead and restarted my computer. A few times of this I decided to take it to a friend who connected my computer directly to his home network. The computer connected to the internet just fine. I was able to surf the net After he double checked the computer and found nothing obviously wrong, I took it back home to try mine again. Again, it would not work, just as before.
