Title:
Qualcomm Atheros wireless card [168c:003e] (rev 32) not supported
Status in linux-firmware package in Ubuntu:
Confirmed
Bug description:
---------------------------------------------------------------
STATUS 2016-03-17:
==========
WARNING: You need at least kernel 4.5.0 for the following new fix to work, else refer to the old method described in post #22
==========
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:

...
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?
