Title:
  Qualcomm Atheros wireless card [168c:003e] (rev 32) not supported

Status in linux package in Ubuntu:
  In Progress

Bug description:
  I have recently installed Ubuntu 15.10 (64-bit) alongside Windows 10 on an Acer Aspire VN7-792G-76ZH and discovered, that the Qualcomm wireless card doesn't work.
  The card has the device id 168c:003e as many other cards, for example the Qualcomm Atheros Killer (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184),
  but it has a newer revision number (32) and the suggested fixes work only partially and the wireless is unusable.

  The computer has just been released this summer and is Intel Skylake
  -based.

  What I have tried:

  I've tried the patch from bug 1383184, which has a fix for the card
  revision 20:

  Make the directory /lib/firmware/ath10k/QCA6174/hw3.0/

  And put in the patch files: 
  board.bin
  firmware-4.bin
  notice_ath10k_firmware-4.txt

  ath10k_pci succeeds in loading the firmware, but it seems that the
  firmware is not working correctly:

  dmesg | grep ath

  ...

  Then it just constantly prints the last two messages on and on.
  I can weirdly enough see the card in iwconfig:

  
  wlp7s0    IEEE 802.11abgn  ESSID:off/any  
            Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm   
            Retry short limit:7   RTS thr:off   Fragment thr:off
            Power Management:off

  And I can see the wireless-icon in the toolbar, but scanning for
  access points or trying to connect to one doesn't work.

  This is the furthest I've gotten. I suspect this card needs a new
  firmware in ath10k?

  I'm currently running the development branch of Ubuntu 16.04 as hardware acceleration support for this PC is currently only supported there.
  The same problem exists in this version too and I'm able to reproduce the issue.

  Hoping to get this fixed, as many other new laptops seem to include
  the same wireless card.
