Title:
  networking disabled and unable to reenable after resume from suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When I resume from suspend my networking is disabled (not just wifi).
  Reenabling it via NetworkManager does not work. Both wlan0 and eth0
  are no longer visible in the output of sudo ifconfig, only lo.

  $ sudo lshw -C network

  I added the line 
  SUSPEND_MODULES="wl"
  to /etc/pm/config.d/config and it seems fine now.

  This bug is a regression. I did not experience it in 13.04 or previous
  versions, just 13.10
