Windows 7 Ult, Windows 8.1 Pro,

You are showing a valid IP on the ipconfig/all.

I searched around on this TG862.

Apparently it has problems working with certain Windows machines. From what I have read upgrading or changing to a different model of modem can fix this problem. I personally would go with a standard modem + an actual router instead of one of these modem/router combo units. Even one of the Comcast tech guys had this problem.

You can read about this rather strange problem with the TG862 in the link below.

Got the problem fixed. In the modem page there is a place for Parental Controls and the problem computer was disabled as a trusted computer. Changing it to enabled as a trusted computer, it now works fine. Thanks for all your help. The Modem was an Arris 862 GW/CT from Comcast.
