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

[Brian Murray]

The firmware for this card isn't included with Ubuntu. The firmware provided in /lib/firmware/ath10k/QCA6174 in Ubuntu 16.04 crashes when used with this card. This included firmware is likely for the QCA6174 instead of this card, the QCA6164.

Yes, you read that right: the files for the QCA6164 need to be a folder called QCA6174 in order for the card to work. Running "modprobe ath10k_pci" shows that the ath10k_pci module looks for firmware in a folder called QCA6174, but not in any folder called QCA6164.

It seems that before this issue can be resolved, the ath10k_pci module must be changed so that it recognizes firmware for both the QCA6164 and QCA6174, in separate folders.

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

HOW TO GET THIS CARD TO WORK:

1) Use a kernel that supports this card

According to WikiDevi, support for this card was added in kernel 4.3. If you're running Ubuntu 16.04 LTS or above, your kernel is fine; skip to the next step. If you're running Ubuntu 15.10 or below, see https://wiki.ubuntu.com/Kernel/MainlineBuilds for info on installing a newer kernel. Alternatively, you can use backports. This is a lot more work, but if you really need to keep using an older kernel for some reason, there are some guides to installing backports in the comments below.

2) Get rid of the firmware folder for this card that's included with Ubuntu:

    sudo rm -r /lib/firmware/ath10k/QCA6174/

3) Download the latest firmware:

    wget https://github.com/kvalo/ath10k-firmware/archive/master.zip

4) Unzip the downloaded file. Inside the ath10k-firmware-master folder is a folder named QCA6174. Copy the QCA6174 folder to /lib/firmware/ath10k:

    unzip master.zip
    sudo cp -r ath10k-firmware-master/QCA6174/ /lib/firmware/ath10k/

5) Rename two of the firmware files like so:

    cd /lib/firmware/ath10k/QCA6174/hw2.1/
    sudo mv firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 firmware-5.bin
    cd /lib/firmware/ath10k/QCA6174/hw3.0/
    sudo mv firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 firmware-4.bin

6) Reboot your computer. Run "lshw -C network" to see if your card is recognized. You can delete the files you downloaded earlier:

    cd ~
    rm master.zip
    rm -r ath10k-firmware-master/

I've verified that this works with Ubuntu 16.04 LTS (with kernel 4.4.0-21-generic); let me know if it doesn't work for you in the comments below.

Some upstream discussion:

http://permalink.gmane.org/gmane.linux.drivers.ath10k.devel/2057

[Brian Murray (brian-murray)]

I also tested the latest 4.0 kernel per jsalisbury and while there was an additonal PCI ID listed in the kernel module, the device in this laptop was not.

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-rc5-vivid/

[Brian Murray (brian-murray)]

I tried to run "sudo lshw" to gather more information but ran into bug 1437436.

[Joseph Salisbury (jsalisbury)]

I built a test kernel that can downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1436940/

Can you try this kernel and see if it allows the wireless device to work? We may have an issue with the firmware, which is being worked on upstream.

[Brian Murray (brian-murray)]

Well the module tried to load it encountered an issue loading the firmware.

[Joseph Salisbury (jsalisbury)]

Thanks for testing, Brian. The test kernel was just a test to see if adding just the pci device id would work. It seems it wont. We'll have to monitor the upstream discussion at:

http://permalink.gmane.org/gmane.linux.drivers.ath10k.devel/2057

I'll post to that thread and say we can test the firmware when it's available.

I also have no rfkill switch, which means that my wireless was hard blocked.
I added my product version into the ideapad-laptop module from git://kernel.ubuntu.com/ubuntu/ubuntu-vivid.git (see attached patch).

Now it is no more hard blocked

Hello,

There are still new folks reporting this issue in the Launchpad bug
report[0]. Has there been any progress on the firmware problem reported
in the comment by Kalle Valo on March 26, 2015[1]?

Thanks in advance,

Comment #18 was a query to upstream on the <email address hidden> mailing list.

[Joseph Salisbury (jsalisbury)]

Recently Upstream has found a way to boot qca6164 with unofficial windows-extracted firmware images on ath10k[1]. However, they still don't have an official firmware release for qca61x4 family for ath10k though.

[1]: http://lists.infradead.org/pipermail/ath10k/2015-August/005752.html

[Joseph Salisbury (jsalisbury)]

Right after I posted my last comment, Upstream stated there is new firmware now available here:

https://github.com/kvalo/ath10k-firmware/commit/7f7e7dda33676ced293de477b03711199ffe5256

Please post how it works (or not).

[Kees Cook (kees)]

With the new files, I still get the ath10k/QCA6174/hw2.1/firmware-4.bin errors. Does the kernel need to be updated for a new driver that looks for a -5 firmware?

[Dan Kegel (dank)]

acer aspire e15 e5-573g-59c3 suffers from similar problem, but with lspci reporting 168c:0042 (rev 30),not 0041 (rev 20).

[Dan Kegel (dank)]

I'm willing to test, too, but the procedure is hard to extract from that email thread.

[Joseph Salisbury (jsalisbury)]

re: comment #23. Response from Upstream:

"Yes - either 4.2-rc or newer, or use Kalle's tree[1].

The qca6174 hw2.1 fix has been pulled into 4.1-stable[2] but it
doesn't understand the ignore_otp_result firmware feature flag so if
you rename the firmware-5.bin[3] to firmware-4.bin you'll need to load
ath10k_core module with "skip_otp=y" parameter.

Also affects the Lenovo U31 series. how soon can we see / test a fix?

[Diego (d13g0)]

I got my card working in Debian testing (I have a Qualcomm Atheros 168c:0041).

Here are the steps, get the latest backports from:

https://www.kernel.org/pub/linux/kernel/projects/backports/2015/07/31/

Get the latest firmware from:

https://github.com/kvalo/ath10k-firmware

Copy the firmware to /lib/firmware/ath10k, apply this patch to the code:

https://github.com/atondwal/linux/commit/22f8a4083883eca3e8a3175315d67d2a04392466

Compile the code and install, then apply this patch to the firmware:

https://github.com/atondwal/ath10k-firmware/tree/master/ath10k/QCA6164/hw2.1

Reboot and modprobe ath10k_pci. Do "lshw -C network"; "ip link show" or "rfkill list" to see if you got your card working.

Mine is working perfectly in my Debian (stretch / sid).

[Diego (d13g0)]

Oh, I forgot, also create a file named /etc/modprobe.d/ath10k.conf with the following line:

options ath10k_core skip_otp=y

Hi Diego,

Could you list down the steps to compile the setup.

[Kees Cook (kees)]

@jsalisbury is there a 4.2 ubuntu kernel we could test with? Here's a tarball with the firmware files. It's unpacked as:

cd /lib/firmware
tar xf /tmp/ath10k-qca6174.tar.bz2

[Bruno Viana (bbviana)]

This firmware has worked for me, Kees!

- Samsung Ativ Book 9
- Atheros QCA6164

[Kees Cook (kees)]

I have not tested these, but IIUC, this is where to get an upstream kernel build, configured for Ubuntu, thought likely without Ubuntu-specific patches: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/

[Diego (d13g0)]

Yes, steps are:

Get the latest backport from https://www.kernel.org/pub/linux/kernel/projects/backports/2015/07/31/ (the zip/tar file)
Uncompress somewhere
Patch the code with https://github.com/atondwal/linux/commit/22f8a4083883eca3e8a3175315d67d2a04392466
Then do:
make defconfig-ath10k
make
sudo make install

Then, get the latest firmware from https://github.com/kvalo/ath10k-firmware/archive/master.zip
Unzip and copy ath10k folder to /lib/firmware/ath10k
Copy these two files (overwrite what you got before) in /lib/firmware/ath10k/QCA6164/hw2.1:
https://github.com/atondwal/ath10k-firmware/tree/master/ath10k/QCA6164/hw2.1

Create a file named /etc/modprobe.d/ath10k.conf with the following line:

"options ath10k_core skip_otp=y"

Reboot and modprobe ath10k_pci. Do "lshw -C network"; "ip link show" or "rfkill list" to see if you got your card working.

[Ryan (ryanw527)]

Following Diego's steps above, "lshw -C network" no longer says my network card is unclaimed and the driver assigned to it is ath10k_pci. However, I see no difference in the functionality of the card (still can not use it).

Lenovo Flex 3 14"
QCA6164 168c:0041

[Diego (d13g0)]

Hi Ryan,

can you copy the outputs of "lshw -C network"; "sudo ip link show" and "sudo rfkill list" ? Can you check for relevant errors with dmesg ("dmesg | grep -i ath" / "dmesg | tail" or just all of dmesg) ?

Also, did you patch the firmware and create the conf file to skip_otp ?

Thanks,
Diego

[Ryan (ryanw527)]

Hi Diego,

I followed every step you outlined including patching the firmware and creating the conf file and adding the skip_otp line. Thank you for your help!

Hi,

clearly the firmware is crashing in your computer (wonder why). Do you have exactly the same chipset as me (lspci -nnk) ?

02:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0041] (rev 20)

Here are my outputs just FYI. I'm not sure why the firmware crashed in your box ("[ 3.584948] ath10k_pci 0000:02:00.0: firmware crashed! (uuid e628e267-4dee-4da1-8a51-ed236bd4fc19)", trying to look for the unsolicited fw crash interrupts).

Mmm,

This is my dmesg:

So, it seems to me that you are using this firmware: https://github.com/kvalo/ath10k-firmware/tree/master/ath10k/QCA6174/hw2.1

When you should be using this one: https://github.com/atondwal/ath10k-firmware/tree/master/ath10k/QCA6164/hw2.1

I was reading my original message and it seems there are some typos, please copy the two files from https://github.com/atondwal/ath10k-firmware/tree/master/ath10k/QCA6164/hw2.1 to /lib/firmware/ath10k/QCA6174 (note the numbers do *not* match, that is the typo).

[Diego (d13g0)]

Edit: copy https://github.com/atondwal/ath10k-firmware/tree/master/ath10k/QCA6164/hw2.1 to /lib/firmware/ath10k/QCA6174/hw2.1 (overwriting the files that should already exist there).

[dagny (dtag1000)]

whatever you do, if you are dualbooting, do not use these drivers.

for some reason, if you put them in the firmware file like the guide says, when you reboot, it deletes the whole dualboot partition.

major bug.

[Miles Krell (mileskrell)]

dagny, could you elaborate? I find it highly unlikely that adding firmware files for this card could have deleted a partition from a drive on your computer. Could your problem have something to do with the kernel you're using?

[Limeth (limeth)]

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
chmod +x ./auto.sh

[Nithya Hariharan (nithyan-hariharan)]

I have a Lenovo G50-45 (QCA6164 Wireless network adapter) with Ubuntu 15.10 (Kernel 4.2) - fully updated as of 17 March 2016. I tried following the steps given under "How to Get this Card to Work:" in the Bug Description. lshw -C network showed QCA6164 as "Unclaimed".

Then following steps in #81 and #90 finally made the card work!!!

Thank you Jeremy!!! Considering my absolute zero knowledge of any kind of programming, the steps were really clear enough that I could follow them and make things work for me :)

[janl (janl)]

New Acer V3-372 laptop with Xenial Kubuntu. Non-working wifi. Hit google, find this ticket. Installed the Kvalo master firmware bundle and wifi worked right away.

Suggest inclusion of kvalo master bundle in Xenial.

[Miles Krell (mileskrell)]

Nithya, sorry about the guide. I forgot that the firmware files have their version number in their names, so they need to be renamed before they'll work. The guide has been updated to reflect this.

I'd appreciate if someone would try following the updated guide and telling me if it works now.

[AndyP (andy-gpshelp)]

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.

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

[AndyP (andy-gpshelp)]

Just to clarify, the guide at the beginning of this report didn't work.

[Miles Krell (mileskrell)]

AndyP, thanks for telling me. I'd really like to reinstall Ubuntu and *then* follow my own guide to see if it works, but I don't want to do this with 16.04 right around the corner. Once it's released, I'll do this and get back to you guys.

I can tell you that I'm not using backports, as I just installed kernel 4.5 a few days ago, and the files in my /lib/firmware/ath10k were all deleted and then replaced following the steps in the guide. I'm also not using any of the dkms stuff that people have talked about for this card.

I guess there's still something I missed. Could you post the output of "modinfo ath10k_pci"?

[Miles Krell (mileskrell)]

Actually, hold on. Could you instead post the output of "lspci -nnk"? I think you might be using a different card.

[Corey Taylor (feeltherussian)]

As at March 18th 2016, confirming that following the guide at the top of the page as well as the Backports method as described at Comment #90 fixed the problem and wifi now works on my Acer Aspire V17. Have attached relevant output from lspci and modinfo confirming h/w configuration for those interested in comparing with their machines.

[AndyP (andy-gpshelp)]

Thanks Miles, output posted here: (last 2 lines relevant I think, but not sure exactly the part you wanted so excuse pasting all)

[Miles Krell (mileskrell)]

AndyP, it looks like you do have a different card. Your card has the PCI ID of 168c:0042, while the QCA6164 has the PCI ID of 168c:0041.

According to http://forums.fedoraforum.org/showthread.php?t=305292, your card is the QCA9377. There's an open bug report for it at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1484159, but I think the following should work.

Your "modinfo ath10k_pci" output doesn't list the QCA9377 firmware files, but they are listed when *I* run this command. I have no idea when support for the card was added, but it's supported in 4.5 (what I'm running). It might be supported in backports somewhere, but the following should be simpler:

1) Install kernel 4.5. There's a guide at https://wiki.ubuntu.com/Kernel/MainlineBuilds.

2) Assuming you downloaded the firmware as explained in the above guide, you have to rename just one file like this:
    cd /lib/firmware/ath10k/QCA9377/hw1.0/
    sudo mv firmware-5.bin_WLAN.TF.1.0-00267-1 firmware-5.bin

If those steps worked for you, I'd put them in the bug report for the QCA9377. Good luck!

[Miles Krell (mileskrell)]

Forgot to say:

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

4) If it still isn't working, run "uname -r" to make sure you're running kernel 4.5.

[AndyP (andy-gpshelp)]

Miles, many thanks for the excellent instructions and analysis. As you may have realised, installing a new kernel is something I've not done before. Followed your lead (and that on the mainbuilds page and I now have a fully working system, using the internal wireless card, which is lightning quick! Thank you vm!
I will post your solution on the page for the other bug if that is ok?

THIS is the reason why I use Ubuntu!!! :)
Andy

PS. I learned a lot from this, so even better.

[Miles Krell (mileskrell)]

Great to hear! I actually didn't know anything AT ALL about this myself until I got my current laptop, less than a year ago. During that time, a lot of people have been working on these cards, and it's gotten easier and easier to get them to work.

Many thanks to Kalle Valo (for the ath10k firmware repo), Anish Tondwalkar (for his QCA6164 firmware), and Diego (for his guide which I originally followed).

Before I first got my card to work, I had to download the backports, apply a patch to them, compile them, install them, and download firmware from multiple places. Now, I just have to download ONE repository and move/rename a few files. All that's left is for someone to get this firmware included in Ubuntu.

As for your question, yes, feel free to spread the knowledge! It's great to have been able to help!

[Miles Krell (mileskrell)]

One last thing: I checked what you added to the other bug, and you'll want to add a link to kvalo's repo (https://github.com/kvalo/ath10k-firmware/).

[Miles Krell (mileskrell)]

@AndyP Actually, I decided to just rewrite my guide for that card, as there were one or two things that were kind of unclear in the guide I wrote in the comments.

[Patrick Lacasse (patrick-m-lacasse)]

I upgraded to Ubuntu 16.04 LTS (4.4.0-21-generic) and my wifi now works out
of the box.
I was using a usb-wifi since I bought my Lenovo Yoga 3 and I'm very happy
because the builtin wifi card is much better.

This bug is solved for me!

However, I can't tell if the firmware I copied last month are used or not.

I just updated to xubuntu 16.04 and it did not work out of the box. However the folder QCA6164 in /lib/firmware/ath10k is already there and I got it to work by simple renaming the folders:

sudo mv /lib/firmware/ath10k/QCA6174/ /lib/firmware/ath10k/QCA6174_moved/
sudo mv /lib/firmware/ath10k/QCA6164/ /lib/firmware/ath10k/QCA6174/

However I am still unable to set up an ad-hoc network to share the ethernet connection with my phone.

Thanks a lot, I have been struggling with this and boot issues with my own Qualcomm Atheros Card for about a day. Everything works fine now. Using Ubunto 16.04, Windows 10 with and Acer R 14.
Thanks again.

[Nicolas (kounips)]

Thanks so much Brian Murray,
I had installed Ubuntu 16.04 from scratch on my Lenovo U31-70 but the wifi wouldn't work. Followed your instructions and now all is good :).

Well since I reported this bug I have found out that the linux-firmware from http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb solved my and my sons 5GHz issue.

I ran these two commands:
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb
sudo dpkg -i linux-firmware_1.158_all.deb

As I stated in the forum "http://ubuntuforums.org/showthread.php?t=2325359&page=2"

After that the wireless card has been working as it should.

[Seth Forshee (sforshee)]

Please try the linux-firmware deb below, which is the version from xenial plus all updates to the QCA6174 which are in version 1.158. If this fixes the issues then I can work on getting these changes into xenial and possibly other releases. Thanks!

[Miles Krell (mileskrell)]

Seth Forshee,

The firmware in the .deb file you provided works perfectly. Thanks.

[Martin Pitt (pitti)]

The verification of the Stable Release Update for linux-firmware has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

[Kees Cook (kees)]

Hm, not fixed for me. still seeing firmware crashes. :(

[Kees Cook (kees)]

Adding ath10k/QCA6174/hw2.1/board-pci-168c:0041:17aa:3545.bin (from the working board.bin in this thread) seems to fix it, though:

e6adc90ecaf55edc656990c6c50193ac board-pci-168c:0041:17aa:3545.bin

[Seth Forshee (sforshee)]

@Kees: I assume it also works if file is just named board.bin? Since that's the way it would be installed if we ship it in linux-firmware ...

[Kees Cook (kees)]

Yup, but I wanted to avoid getting overwritten each time linux-firmware gets updated. ;)

[Seth Forshee (sforshee)]

I guessed as much, just making sure. I'll inquire as to why that board.bin hasn't been pushed out to linux-firmware yet, and as long as there isn't some reason why we shouldn't I'll pull it into xenial.

[Seth Forshee (sforshee)]

Hang on, there might be a problem. That file is from https://github.com/atondwal/ath10k-firmware and isn't in https://github.com/kvalo/ath10k-firmware that I can find. So as far as I know we don't have a license to redistribute that file.

I'll go ahead and inquire with Kalle, hopefully we can get something that works from QCA directly.

[Seth Forshee (sforshee)]

@Kees: Could you provide dmesg after the firmware crash you see with the board files from linux-firmware? Thanks!

[Timothy Ward (twardprof)]

Thank you! This was the solution for me after many unsuccessful attempts.

[bert (bvr-c)]

great instructions and explanations!

it works for my lenovo ideapad, ubuntu 16.1 and atheros card, thank you very much!
