I have made a script that patches this incapability for the Lenovo
U31-70 laptop. Works on elementary OS, should work on any Ubuntu 14.04.
GitHub repository: https://github.com/Limeth/lenovo-u31-70-patches


Steps:

git clone https://github.com/Limeth/lenovo-u31-70-patches.git
cd lenovo-u31-70-patches/wireless-adapter-patch

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

Status in linux package in Ubuntu:

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 very 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 4.4.3.  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 the ath10k folder's contents to
  /lib/firmware/ath10k.

  3) 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.
