I am running windows 7 build 7022 beta. i purchased a dlink di-634m 2.4ghz airplus extreme 108g mimo router. Also a arris cable modem and my isp is comcast. the problem is when i connect my pc to my modem (via ethernet cable) i get full internet and it's all fine. but when i connect my pc to my router and my router to my modem all i get is local internet. i thought about uninstalling norton 360 and then reconnecting it all then re-installin 360.. When i have windows diagnose it's says cannot connect to primary dns, and also very often it will say that my modem has an invalid ip configuration... But the thing is when i connect my router to my pc it doesnt ahow up as a device or anything. which means i can't access it to change any of it's configuration.. Can anyone please help??
