[Dennis Marttinen <dennis.marttinen@xxxxxxxxxxx>]

Thanks to everyone for research and support so far. As Christophe
Chisogne mentioned, a new board-2.bin and a new firmware-4.bin file have
been added to kvalo's ath10k-firmware repository and the [168c:003e]
(rev 32) is now working correctly using the files from kvalo's master
branch. I've also investigated, that ath10k_pci now wants to load both
board.bin and board-2.bin, so I expect that they both are required for
correct functionality (5GHz maybe? Someone with a new access point could
check if it works now).

I'll update the status and add some new instructions to the bug
description.

Also, the bluetooth lag problem exists on ath6k as well (tested), it
might be related to the atheros driver/wifi card family as a whole
rather than just this card.

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

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  ---------------------------------------------------------------

  STATUS:

  Currently there is a fix for this problem in post #22 (originally post
  #19, but reposted due to command typos!) which seems to have fixed the
  issue for many. This bug is unique to revision 32 of the card
  [168c:003e], fixes for older revisions don't seem to work.

  There are a couple of issues regarding the fix for some people (not
  all):

  1. Wireless works, but network throughput stops some time after
  connecting to access point

  2. Bluetooth communications take a noticeable performance hit when
  transferring something over WiFi

  ---------------------------------------------------------------

  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 in it or 16.04.
  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.

  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

  [   84.206218] ath10k_pci 0000:07:00.0: could not suspend target (-11)
  ...

  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?
