I recently re installed windows XP on my Dell Dimmension 2400 and now I can't connect to my Charter internet. I reinstalled the driver to my ethernet controller and set up my local area connection, but I still can't access the web. I can use the same connection perfectly on my Mac, so I don't know what the problem is. I can even see the network as connected on my system tray, my computer always acts like I am offline. Please help!
