Tried current workaround like is written in section "STATUS 2016-03-17:"
of the description on the Ubuntu 15.10 Acer v3-372-582Z with kernel
4.2.0-34-generic. After reboot network manager icon in the status bar
disappeared, wired is working, wireless is found in network section of
the system settings with no networks displayed.

Maybe I'm doing something wrong?

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

Status in linux package in Ubuntu:
  Confirmed

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

  STATUS 2016-03-17:

  The support for this card has now been merged to
  https://github.com/kvalo/ath10k-firmware. The repository now contains
  the required board.bin, board-2.bin and firmware-4.bin files for the
  card to initialize and connect to a bgn-access point (5GHz (ac-
  protocol) is still untested, feel free to modify this if you can
  confirm it works). Here are the new commands to get you online:

  sudo mkdir -p /lib/firmware/ath10k/QCA6174/hw3.0/

  sudo rm /lib/firmware/ath10k/QCA6174/hw3.0/* 2> /dev/null

  sudo wget -O /lib/firmware/ath10k/QCA6174/hw3.0/board.bin
  https://github.com/kvalo/ath10k-
  firmware/blob/master/QCA6174/hw3.0/board.bin?raw=true

  sudo wget -O /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin
  https://github.com/kvalo/ath10k-
  firmware/blob/master/QCA6174/hw3.0/board-2.bin?raw=true

  sudo wget -O /lib/firmware/ath10k/QCA6174/hw3.0/firmware-4.bin
  https://github.com/kvalo/ath10k-
  firmware/blob/master/QCA6174/hw3.0/firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1?raw=true

  Reboot or reload the ath10k_pci module and you should be able to
  connect!

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

  STATUS 2015-12-22:

  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

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

  Original 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:

  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?
