When I first installed Windows 7, I was able to get on the internet in just a couple of minutes with no problems. So I downloaded the Norton 360 beta, and while installing it I lost my internet connection half way thru the install. At first it looked like my modem wasn't connecting with Yahoo, and it looked like a Yahoo problem. Yahoo would not recognize my modem, so then I thought maybe it is the Norton software, as I lost my connection while installing it. So I removed N360, and still couldn't get on the internet, so then I tried a system restore and that fixed the problem.
