Thanks for the log. Putting the interesting excerpt here for
convenience:

Mar 09 23:27:59 fry NetworkManager[1000]: <info> (wlan0): device state change: secondaries -> activated (reason 'none') [90 100 0]
Mar 09 23:27:59 fry NetworkManager[1000]: <info> NetworkManager state is now CONNECTED_LOCAL
Mar 09 23:27:59 fry NetworkManager[1000]: <info> NetworkManager state is now CONNECTED_GLOBAL
[...]
Mar 10 00:37:20 fry NetworkManager[1000]: <info> sleep requested (sleeping: no  enabled: yes)
Mar 10 00:37:20 fry NetworkManager[1000]: <info> sleeping...
Mar 10 10:04:24 fry NetworkManager[1000]: <info> waking up...
Mar 10 10:04:24 fry NetworkManager[1000]: <info> (wlan0): device state change: activated -> unmanaged (reason 'sleeping') [100 10 37]
Mar 10 10:04:24 fry NetworkManager[1000]: <info> (wlan0): deactivating device (reason 'sleeping') [37]

So it seems that the "activated -> unmanaged" action should be done
*before* "sleeping...", and then it just forgets to bring it back up
after waking up. Here it has the correct order, so that sounds like a
race condition.

This part (logind interaction) hasn't actually changed in quite some
time. Out of interest, do you get this error under upstart too? This
doesn't actually sound specific to using systemd as init, but it would
be nice to confirm that. Otherwise it's another data point for debugging
this. Thanks!

Title:
  No wifi connection after suspend with systemd

Status in One Hundred Papercuts:
  Confirmed
Status in network-manager package in Ubuntu:
  Incomplete

Bug description:
  Using systemd as my default init system if I resume from suspend my
  laptop, it doesn't automatically reconnect to the wireless network and
  it doesn't list the available network connections.

  The only way to get a wireless connection is to restart the network-
  manager daemon or going to the gnome-control-center, disable wireless
  and enable it again.
