I have a desktop computer connected to the internet via a broadband connection (using a Motorola Surfboard Modem & a DLink router). Yesterday I set up another desktop comp (using Windows XP) and connected the ethernet cord to the back of the tower. I had trouble getting the Internet to work, went through the various troubleshooting steps, and somehow (probably just dumb luck) got the Internet te work. A little while later I lost the connection and cannot get it back. 1st I called Gateway for help - they said the IP address was invalid and I needed to call the Internet Service Provider. I called Cox and they said the problem is with the router. (Again, the other computer is hooked up to the same router and having no problems). Of course the router is no longer covered for technical support. I went to their webpage for help and tried a few things that did not work. Help!?!
