Comment 71 for bug 1415880

In case you are running on problems with the NetworkManager (version 1.0.4-ubuntu5) after the official upgrade to Wily (messages "[platform/nm-linux-platform.c:2782] do_change_link(): platform-linux: do-change-link: failure changing link 4: No such device (31)" or similar) after wakeup from a suspend, simply restart the NetworkManager with a suitable script in /lib/systemd/system-sleep in order to get autoconnect working again.
