  No WiFi after suspend (Qualcomm Atheros AR9462 [168c:0034])

Status in linux package in Ubuntu:

Bug description:
  After a fresh install of Xenial (16.04) on my laptop (Acer Aspire
  VN7-591G), the WiFi does not work after suspend. It worked without
  problem on the latest Trusty version (14.04.4).

  The Wireless module is:

  Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network
  Adapter [168c:0034] (rev 01)

  Steps to reproduce:
  - Turn the computer on. Make sure WiFi is on and working.
  - Suspend the device (e.g. by closing the lid)
  - Wake the device up (by pressing the power button)
  - Check the network connectivity

  Expected result:
  - WiFi can be used after suspend

  Actual result:
  - No WiFi after suspend. The device has to be restarted to get the WiFi connection back (de-activating/re-activating the "Enable WiFi" or "Enable Networking" from the Network menu does nothing).
