Hi, I have a brand new Acer F5-571 with a qualcomm atheros device and the wireless doesn't work. I removed windows10 and installed the latest ubuntu-mate wily 15.10 (same issue in mint 17.3). I'm somewhat of a newbie so please be gentle.  I have tried a number of the points in this bug report to no avail, posts 81/90, the intro notes and others have all been tried. comment 118 didnt work, for some reason dkms would not install. 
Kernel 4.2.0-34-generic 
sudo lshw -C network

Really need to get this wireless card working. Suggestions? If so please
step by step, don't assume I know how to do stuff.

Title:
  Qualcomm Atheros QCA6164 802.11ac Wireless Network Adapter [168c:0041]
  is not supported

Status in linux package in Ubuntu:
  Confirmed
Status in linux-firmware package in Ubuntu:
  Confirmed
Status in linux source package in Vivid:

Status in linux source package in Wily:
  Confirmed

Bug description:
  This card remains unsupported out-of-the-box by the ath10k_pci kernel
  module.  At this point, it looks like kvalo's ath10k-firmware repo
  just needs to be pulled in.

  Speaking of which, that repo contains a folder for the QCA6174, but
  not for the QCA6164.  The firmware in the QCA6174 folder works for the
  QCA6164; I still find it strange.  I'm not sure how well the actual
  QCA6174 [168c:003e] firmware works.

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

  HOW TO GET THIS CARD TO WORK:

  As of February 26, 2016, this has become relatively simple.

  I'm unsure of what version kernel you need to be using - it's either
  at least 4.0 or at least 4.2.  I'm currently using 4.5.  If the kernel
  you have isn't working, try that one.

  1) Get the latest firmware from https://github.com/kvalo/ath10k-
  firmware/archive/master.zip

  2) Unzip this file, and copy contents of ath10k-firmware-master to
  /lib/firmware/ath10k.

  3) Rename two of the firmware files like so:
      cd /lib/firmware/QCA6174/hw2.1
      sudo mv firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 firmware-5.bin
      cd /lib/firmware/QCA6174/hw3.0
      sudo mv firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 firmware-4.bin

  4) Reboot your computer.  Run "lshw -C network" to see if your card is
  recognized.

  If you created a "/lib/modprobe.d/ath10k.conf" file earlier to disable
  otp, you can remove it.  I did, and the card still works fine.
