you don't have a global ip, is the router connected to internet? Have you tried without a router? –  Alvar Jul 15 '13 at 22:36
    
May we see: nm-tool and also ping -c3 192.168.0.1 –  chili555 Jul 16 '13 at 1:33
    
Alvar, Router is connected to the internet, All my other computers runs. I have windows running alongside this Ubuntu and they work fine. Ubuntu did not have any issue until I updated to 12.04. Thanks for the help! –  Dave Jul 16 '13 at 17:30
