It seems that this bug affects Precise. Today I installed Ubuntu 12.04 LTS and after login I got the message that network is disconnected and I am offline. I tried to edit /etc/network/interfaces but nothing was changed ( I used the same config as on Debian 6.0 where connection works fine). So after every reboot I should go to shell and run it by myself using "dhclient eth0".
