I had a similar problem on XPS15 laptop.
For me all networks, WiFi and cable had no internet and no netbios over TCP/IP. When I tried to change the adapter settings for TCP/IPv4 i got a weird error message to say adapter card must be installed first.
I removed McAfee ages ago, using Sophos AV instead. So in my case the problem must be caused by windows 7 or other driver updates.
I rebooted in Safe Mode then ran Windows Restore back to the end of July 2012. The problem went away immediately.
Now Windows has updated automatically and the problem has not recurred. Fingers crossed...
