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?

I managed to find a solution to this problem and have wireless now fully working!

I found a Github link in jeremy31's post from the Ubuntu Forums link by Db-d (post #18, http://ubuntuforums.org/showthread.php?t=2304154&p=13398554), which led me to Fabian Olesen's firmware versions forked from kvalo's ath10k-firmware repository. From these different (and new) firmware files I managed to construct a working combination.

Here are the commands, which should get the rev 32 card running:

If the firmware file directory doesn't exist, create it:
sudo mkdir -p /lib/firmware/ath10k/QCA6174/hw3.0/

If the directory already exists, backup everything important from it:
mkdir ~/ath10k_old
cp /lib/firmware/ath10k/QCA6174/hw3.0/* ~/ath10k_old

Then delete it's old contents:
sudo rm /lib/firmware/ath10k/QCA6174/hw3.0/*

Now we can start downloading the new board file and the firmware:

sudo wget https://github.com/FireWalkerX/ath10k-firmware/blob/7e56cbb94182a2fdab110cf5bfeded8fd1d44d30/QCA6174/hw3.0/board-2.bin?raw=true /lib/firmware/ath10k/QCA6174/hw3.0/board.bin

sudo wget https://github.com/FireWalkerX/ath10k-firmware/blob/7e56cbb94182a2fdab110cf5bfeded8fd1d44d30/QCA6174/hw3.0/firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1?raw=true /lib/firmware/ath10k/QCA6174/hw3.0/firmware-4.bin

Make the files executable:
sudo chmod +x /lib/firmware/ath10k/QCA6174/hw3.0/*

Reboot and your wireless should now be working!

If this fix works for you Db-d and Oliver, this thread should probably be marked with "patch released" or something similar and possibly the fix merged upstream? I'm not sure how to do this (or what to do next) so could someone give an advice?

Good morning,

I looked one more time over the problem this morning and I found that it is looking for board.bin

[ 2.151400] ath10k_pci 0000:07:00.0: Direct firmware load for ath10k/QCA6174/hw3.0/board.bin failed with error -2

The board.bin in /lib/firmware/ath10k/QCA6174/hw3.0 was called differently (board-2.bin).

I just renamed the file to board.bin

sudo mv /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin /lib/firmware/ath10k/QCA6174/hw3.0/board.bin

and now it is working fine!

Thank you!

Yeah, sorry there's a little typo in both of the wget commands, I've missed the parameter specifying the output file name.
Here are the commands for the fix again, this time with the correct parameters and some other little tweaks.
If the /lib/firmware/ath10k/QCA6174/hw3.0/ directory already exists, remember to backup everything from it in case you want to restore the previous configuration.

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

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

sudo chmod +x /lib/firmware/ath10k/QCA6174/hw3.0/*

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

After a reboot your wireless should be working.

The status of this bug should probably not be "In Progress" after a working solution has been found, but please correct me if I'm wrong. As I'm not yet familiar with this bug reporting system, could someone advice me further?

PS. I'm glad you figured it out Oliver, sorry for the extra hassle.

Hello Dennis,

thanks for your work so far. I ve got a new Lenovo u31-70. It has the QCA61x4 in it.
lspci -nn shows me Qualcomm Atheros Device [168c:041].

I tried your commands, but it did not work for me. There was no alarm or like that within in the terminal. But after the reboot it did not show any wireless networks to connect.

Do you have an idea?

Thankfully

Dennis Marttinen (technowelho) wrote :

Hi Tim,

I can have a look at the card if you can tell me it's revision number. If the card has one, it can be found after the device id in lspci, for example: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32) <- here

This bug report is for the [168c:003e] (rev 32) though, so you might need to make a new one for your version [168c:041]. You should also check out some other Atheros bug reports for the card, but since your PC relatively new, it might be a new issue.

@Dennis Marttinen (technowelho)
Thank you, your suggestion worked well, but now, I sometimes have connection issues (no data throughput), but nothing special shows up in dmesg. When I reconnect the wifi it works again. Do you have any ideas? Or maybe what logfile I should start looking?

Thanks,

Dennis Marttinen (technowelho) wrote :

Hi Daniel,

I had similar connection problems, as I had to use an USB WiFi dongle and cable ethernet before I got the Atheros card working. This had changed /etc/resolv.conf, so when removed all parameters from the file and replaced them with the following, the "freezing" issue didn't occur any more:

nameserver <your local loopback address, for example 127.0.1.1>
search <address of your router, for example 192.168.1.1>

You can find the local address with the command:

ifconfig lo

And the router address by looking for "Default Route" in your network settings.

Remember to check /etc/network/interfaces for any unnecessary parameters, mine contains only:

auto lo
iface lo inet loopback

The wireless interface doesn't require any parameters. Otherwise I'm glad that the fix worked for you as well.

/Dennis

dan (d-dan-3) wrote :

Hey Dennis,

/etc/resolv.conf already contained 127.0.1.1 as a name server.
My default gateway is 192.168.0.1 but I think changes would be overridden by a reboot. (so I have not tried it yet)

When this connection issue occurs, I cannot even access the default gateway(my router) via its IP (the connection is always pending). Only after reconnecting to the network it works instantly.

/etc/network/interfaces does not contain any unnecessary parameters.

Daniel

Dennis Marttinen (technowelho) wrote :

Daniel, do you have any other network connection (wireless over USB, ethernet etc.) active at the same time? And you can safely put the parameters in /etc/resolv.conf, my configuration hasn't changed even after numerous reboots.

/Dennis

dan (d-dan-3) wrote :

Hey Dennis,

No this is the only one. Prior to that, I have used Ethernet.

I changed resolv.conf but I could not verify whether that helped, after a reboot it was reseted again.

Same issue, same solution, and same problem : wireless network seems ok and few second laters, no more working.
ifconfig show normal ip's, dmesg no specific message.
I have to disconnect and reconnect for it works, for few seconds only.

All configuration files are set to defaults, only one wireless card.

Hey Goacid,

I have now tried disabling IPv6 because I saw warnings in the syslog right about the same time as when the issue occurred:
NetworkManager[730]:<warn> (wlp7s0): Lowering IPv6 MTU (1280) to match device MTU (0)
NetworkManager[730]: <warn> (wlp7s0): IPv6 MTU (0) smaller than 1280, adjusting
NetworkManager[730]: <warn> (wlp7s0): Raising device MTU (0) to match IPv6 MTU (1280)

So until now, it seems to work.

Please add yourself to the "bug affected" persons.

Hi Dennis,

Thank you so very much. On my new Acer R5-471T-52EE, your solution fixed the WiFI problem!!!

I have Ubuntu 14.04.3 LTS, I upgraded kernel to "4.2.0-21-generic" and then followed your solution exactly. The dmesg also showed me the following messages

Dennis Marttinen (technowelho) wrote :

I don't think this bug is a duplicate of bug 1383184, as the suggested fix:

"For now, you guys could use 15.10 (purge the ath10k-dkms if you tried installing it), and make a copy of https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/ath10k/QCA6174 into /lib/firmware/ath10k/"

didn't work for me. "dmesg | grep ath" just reports the same old error as in the description. Also, I have already tried the patches from that bug report earlier and made this new one especially because it's fixes didn't work, as you can see in the beginning of the description:

"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."

That said, I've found out how it's only partially working. The suggested firmware-4.bin file from that report does work, but the board.bin file doesn't. If you replace the board.bin file with the file suggested in this bug report's post #22 the combination starts working.

The status of bug 1383184 is marked as "fix released", but having the latest network-manager and linux-firmware on kernel 4.4.0-040400rc5-generic (Ubuntu 15.10) does not fix the issue with the REVISION 32 of the card, which needs the customized board.bin file.

So, not a duplicate?

I've also found out, that my Bluetooth mouse starts lagging behind when downloading something (for example watching a YouTube video). Other Bluetooth devices also seem affected, but the slowdown ends instantly when downloading/uploading over WiFi stops. This has probably something to do with the card's radio, as it manages both Bluetooth and WiFi? Are the channels too close to each other? Maybe there is a way to adjust the bandwidth or frequency if they overlap.

Hey Dennis,

thank you for your workaround. I had the same problems with not working wifi on my Acer Aspire V15 Nitro - Black Edition laptop.

This is my lspci output:

After using your fix, the wifi works like a charm but as you said my bluetooth mouse is lagging horrible while transfering data over wifi.

Anything new on this problem? A final fix would be great. :)

My Acer Aspire v13 has been wifi-less since, well, a long time.
I too had found the https://bugs.launchpad.net/bugs/1383184 bug report, but neither the first workaround nor the released fix had any affect. But this (post 22) fixed it. I can live without bluetooth in the meantime.

I got wifi working on a Acer Aspire V13 (v3-372) through the instructions in #19. Thank you!

However I noticed that I am unable to connect to a secured (WPA PSK) 5GHz network. dmesg shows that the authentication times out.
The non-5GHz version of the same network works fine.
Is this also related to the driver or do I need to look at another component?

Dennis Marttinen (technowelho) wrote :

Hi Niko,

I've tested out a few 5GHz networks too and have found out the driver can't handle them.
Older Atheros cards using other firmware and board files are connecting to 5Ghz,
so I think it has something to do with the board file, since the stock firmware-4.bin works with the special board.bin file.

It would be great, if someone familiar with ath10k could look at the source code (the urls in post #19).

Then there is a way to repack board files for Linux which is described here:

The driver is installable from within Wine prefix (haha #2). I've attached the contents of Qualcomm Atheros folder that is put installed under Program Files (x86). There is a whole bunch of binaries, eeproms, etc. there. Maybe someone could find it useful.

Thanks to everyone for research and support so far. As Christophe Chisogne mentioned, a new board-2.bin and a new firmware-4.bin file have been added to kvalo's ath10k-firmware repository and the [168c:003e] (rev 32) is now working correctly using the files from kvalo's master branch. I've also investigated, that ath10k_pci now wants to load both board.bin and board-2.bin, so I expect that they both are required for correct functionality (5GHz maybe? Someone with a new access point could check if it works now).

I'll update the status and add some new instructions to the bug description.

Also, the bluetooth lag problem exists on ath6k as well (tested), it might be related to the atheros driver/wifi card family as a whole rather than just this card.

Somehow your firmware didn't update from kvallo github, you should delete the ath10k-firmware folder from home and use git clone again

Sorry! I forgot to add, that you need the latest mainline kernel (4.5.0) for the updated fix to work. My mistake, I will update the description. If you don't want to update your kernel, you have to use the old method (post #22), but 5GHz wireless will definitely not work with it. The new kernel has an updated version of the ath10k driver, which can utilize both board.bin and board-2.bin from kvalo's repository (now enabling 5GHz), but the ath10k version Ubuntu 15.10 currently uses in it's kernel (4.2.0) requires the single board-file from FireWalkerX.

Sorry for the inconvenience!

Gary, I've figured out that the binary files are read by ath10k rather than executed directly, so they don't need executable permissions.

Do you still use the skip_otp=Y parameter with kernel 4.5?

OK -- I have no clue what my issue could be and am starting to get a bit frustrated with this WiFi chip because it seems like there's nothing I can do about it. I'm using the Ath10k QCA6174 chipset on a Acer Aspire V Nitro laptop. Every other device I have connects at a much faster rate to my Asus AC66U WiFi router, but for the life of me I cannot get my laptop to connect to it at a rate over 1Mb/s, according to iwconfig and the nm-applet tool.

I also cannot connect to the 5gz band on the router either, while all my other devices have no issues. When I got the laptop I was able to connect to either 2.4 or 5.0 bands in Win10, but since I've installed Ubuntu it's been hopeless and I've tried just about every solution out there. Granted, when I first got the laptop getting this chip to connect to anything WiFi was pretty much a lost cause, and I know that the driver for it has come a long way, but there are still several issues with it that's really degrading the potential of the hardware.

Even on the 2.4ghz band, the only one I'm able to connect to I'm having severe degradation of service and it sometimes won't even connect to the access point and crashes nm-applet. Can someone please explain why it is that it's showing only a 1Mb/s bit rate and why I'm unable to connect to the 5ghz band on the router?

Hi Dennis or anyone who can help,

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

After reboot the wifi option was no longer visibe, ls /lib/firmware/ath10k/QCA6174/hw3.0 showed both board.bin and board-2.bin

so I did
sudo mv /lib/firmware/ath10k/QCA6174/hw3.0/board.bin /lib/firmware/ath10k/QCA6174/hw3.0/board.bin.bak

now ls /lib/firmware/ath10k/QCA6174/hw3.0 shows board-2.bin and board.bin.bak but still no wifi option on the after reboot?

Anyone have any suggestions on what I need to do? I would rather have disconnecting wifi than no wifi at all, also I'm completely new to linux and have no idea what I am doing so please be gentle!

Ok so also tried
sudo mv /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin /lib/firmware/ath10k/QCA6174/hw3.0/board.bin.bak
which seems to have done nothing but eliminate board-2.bin ><

I'm also having a similar issues, I have a xps 9360 with the killer 1535 board running on ubuntu 16.10. The weird part with my case is that I'm unable to make new requests while the existing ones keep working fine (like a download or a hangouts/skype call, they never drop).

Example, when browsing a website, the main page load, but the images from a CDN not. Its very similar to a DNS problem, but I tried google and open DNS without success. Also, I tested with my other computers and devices and they are all working fine.

Another example is with music streaming, that fails only when changing the music file.

I already did the fix suggested by #22, and also updated my linux-firmware to 1.163 (http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/)

Anyone had similar problems?
Would ubuntu 16.04 work better to me?

FWIW, I did the following:

$ git clone git://kernel.ubuntu.com/ubuntu/linux-firmware.git
...
$ cd linux-firmware
$ git checkout bionic
...
$ sudo cp ath10k/QCA6147/hw3.0/* /lib/firmware/ath10k/QCA6147/hw3.0/

The new firmware seems to drop my connections much more infrequently. Perhaps upgrading the firmware in the linux-firmware package is the right solution here.

I use the built-in Ethernet and not the built-in WiFi so not a big deal today. But would still like to see it fixed some day. I intentionally bought a brand new laptop first released two years ago so it wouldn't have bleeding-edge bugs :(

WinEunuchs2Unix,
Why don't you use HWE stack?

Kai-Heng,

I was on Hardware stack for awhile but had problems with. Remember many users opt out of HWE even though it's the default.

I was running 4.14.2 mainline but `kexec` was broken after 4.12 so I dropped into 4.4.0-101 provided by Ubuntu to make `kexec` work properly.

I do have Ubuntu kernels 4.10.0-28, 4.10.0-37...-38 and -40 but I have to analyze the release dates to figure out which real Linux kernel version they are equivalent to.

Are you suggesting an HWE version off the 4.10 kernel tree fixes the problem and solution in comment #22 is no longer needed???

If the fix is from firmware, then we should update the firmware for the device in question.

Can you try the firmware in [1] instead of the ones from #22?

Kai-Heng sorry I can't try it right away. I'm still struggling with systemd's kexec-load@service to quicken reboot times as I struggle with nVidia having HDMI sound turned off by default BIOS POST. In the meantime I've blacklisted `ath10k_pci` and that appears to have saved 2-3 seconds off the boot.

The latest firmware is not included in the linux-firmware package on artful. Is this intended? I see that it is only included in the latest LTS and bionic.

Does this mean that the firmware will not be added to artful?
