No Internet

I installed windows 7, but I have no internet. I am using an ethernet cable, the internet worked when I was using vista on the computer. My cable is fine it works with other computers, I have called my internet service provider and they say they can see my computer on their end. In the network and sharing window it says I am connected to the internet. I can not do anything internet wise but it says my internet is working properly, which it clearly isn't. Someone give me some ideas please because the "geek squad" at best buy didn't fix anything.
