I upgraded from Ubuntu 11.10 to 12.04 yesterday. I am running a BSNL Broadband DSL conenction. The wired network suddenly dissapears and the computer stops detecting the ethernet card after sometime. However, after rebooting, it again becomes alright.

sudo dpkg --configure -a
This solved the problem for me. All configuration files were rewritten including the ones for network-manager. I must add that I have a Intel Corporation PRO/Wireless 4965 AG on a Dell XPS M1530.
