Status changed to 'Confirmed' because the bug affects multiple users.

NetworkManager seems to have been restarted quite fast after the resume from suspend, but this really looks like the issue we've had with the systemd logind proxy for the PrepareSleep method.

Reassigning to systemd.

'sudo restart network-manager' works for me not sure why systemd fingured?

Bug still persist in current utopic beta. It is extremely annoying and I do not imagine a situation the utopic will be released without fixing it.

This works perfectly on Ubuntu 16.04 with systemd:

Is this a duplicate of bug 1380480 ?
