[Sergio Callegari <sergio.callegari@xxxxxxxxx>]

I see it on a laptop that does not connect automatically to the wireless
network after wakeup. But I have the same issue also with a desktop with
wired ethernet.  So a more appropriate title would be 'network manager
fails to reconnect after resume', because the issue is not wifi
specific.

After a suspend/resume cycle, network manager does not reconnect.

For the desktop, given that this used to be a machine going to sleep
when unused and being waken from the lan, the issue is pretty bad. The
machine wakes... but with no network. Network manager stays there for
ever, with the connection ready and selected for automatic connection,
but does not even try to start the connection.

Since it completely breaks the usability of wol, please rise priority.

This is something recent.  I have also started to see it about November.
Furthermore, it used to work just fine with 14.04.

Bug description:
  After suspending ubuntu the wifi doesn't work. The solution given here
  (http://askubuntu.com/questions/368671/ubuntu-13-10-wifi-not-re-
  connecting-after-suspend) worked for me but when I have updated my
  Ubuntu now it won't work. I have tried to test mainline kernel but it
  won't to boot with it.

  To reproduce the bug : just suspend the computer and then power it.
  There's no wifi network until you restart the computer.
