Correction: No need to suspend, removing the cable and re-plugging causes the same problem. After the cable was removed once, network manager always reports "Ethernet Networks: disconnected".
** Summary changed: - eth0 down after suspend + No ethernet connection after connection was dropped once -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1176351 Title: No ethernet connection after connection was dropped once Status in “network-manager” package in Ubuntu: New Bug description: Raring, on a Thinkpad T61, with e1000e network driver. After resume form suspend, eth0 is down, but network manager shows "network connected". Reconnecting via the indicator menu does not work. When I type "sudo service networking restart" in a terminal, my whole session breaks: unity/compiz disappears, leaving the desktop unusable. Trying to use nmcli from a command line reports that dbus session cannot be found. I need to reboot to recover from this state.
