I don't think this bug is a duplicate of bug 1383184, as the suggested
fix:

"For now, you guys could use 15.10 (purge the ath10k-dkms if you tried
installing it), and make a copy of
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-
firmware.git/plain/ath10k/QCA6174 into /lib/firmware/ath10k/"

didn't work for me. "dmesg | grep ath" just reports the same old error
as in the description. Also, I have already tried the patches from that
bug report earlier and made this new one especially because it's fixes
didn't work, as you can see in the beginning of the description:

"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."

That said, I've found out how it's only partially working. The suggested
firmware-4.bin file from that report does work, but the board.bin file
doesn't. If you replace the board.bin file with the file suggested in
this bug report's post #22 the combination starts working.

The status of bug 1383184 is marked as "fix released", but having the
latest network-manager and linux-firmware on kernel
4.4.0-040400rc5-generic (Ubuntu 15.10) does not fix the issue with the
REVISION 32 of the card, which needs the customized board.bin file.

So, not a duplicate?

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

Status in linux package in Ubuntu:
  Confirmed

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 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:

  ...

  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?
