Thanks to Dennis! Now my alienware can reach internet through wifi!!!

My setup is:
Alienware 15 with Qualcomm Atheros wireless card QCA6174 802.11ac (rev 32)
Ubuntu 15.10

I first try "apt upgrade", as instructed by Bug 1383184 -- https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184 
Apparently, it does not work at all.

After 6 hours struggle, I find this post and followed Dennis in #22. Now
my alienware 15 works:)

Cheers!

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?
