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.

$ lspci | grep Ethernet 
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)

Specs:

  • Lenovo Ideapad Z570
  • Intel i5 2nd Gen. processor
  • 3 GB RAM
  • So what's the problem here? – harisibrahimkv May 2 '12 at 5:45
  • The wired network keeps disappearing. I think its a bug. – TeknasVaruas May 2 '12 at 5:52

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.
