I do not know what other information you need other then every other device either phone laptop tablet ipod will conncet, except my laptop so i know there is a problem. Thanks for your help in advace.

so you wifi and ethernet dont work? can you connect with other devices? have you contacted your isp to make sure your interwebs not down?

What does Control Panel > Network and Sharing Center show for your connection? And, when there, go to Change adapter settings. Once there, right click on whatever adapter icons are shown, and run Diagnose.
