I have a strange networking issue. I can ping anything on my subnet, but can't seem to get much beyond that. I can't resolve DNS names, but I can get a response from google's IP (188.8.131.52). That's the part that confuses me. If it was a subnet or DNS issue it wouldn't appear like this. This only happened once I upgraded from 11.10 to 12.04. Does anyone have any suggestions?
