Bug 1276360

This isn't a kernel issue.  Firmware is provided by the linux-firmware package.

It looks like the generic firmware (the last one it tries to load) was added to the upstream linux-firmware git repo on Oct 15 with:

commit aab28b04bcae237f871f4594bbc654da0cf36b50
Author: Kalle Valo <kvalo.com>

    ath10k: QCA6174 hw2.1: add firmware WLAN.RM.1.1-00141 and board.bin
    
    Add initial firmware and board files for QCA6174 hw2.1 family of chipsets.

I'll try and get an updated linux-firmware package out soon.

I haven't had the time to investigate this, but on an Aspire VN7-791G with QCA6174, the firmware included in 66d3d8d7 or bbe4917c does not work. The device is turned on, it scans and finds APs in range, but it can not connect.

I tried the latest firmware (v1.1.1-00157) that Kalle Valo hosts on his github:
https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw2.1
and that does work. It's not included in the linux-firmware kernel.org repo yet.

Dear all,

I am having this issue as well and I believed I have tried all solutions show here but nothing works. I have posted it here in detail http://www.forums.fedoraforum.org/showthread.php?t=308949, and what it says is that I have a inspiron 15 5557 which uses a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter and just installed F23 and I cannot get the wifi to connect. I tried to update the firmware as suggested here  https://lists.fedoraproject.org/pipermail/package-announce/2015-November/170677.html using both "dnf --enablerepo=updates-testing update linux-firmware" and "dnf update linux-firmware" but no updates were available. After that I try to copy the firmware directly from the link https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174 into the folders /lib/firmware/ath10k/QCA6174/hw3.0 and /lib/firmware/ath10k/QCA6174/hw2.1 and restarted the computer as suggested here https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/firmware in "Update Firmware" and again no wireless at all. The output of "dmesg | grep ath10k" is

Thank you all for your help.

I have been able to solve the problem after checking this post https://bbs.archlinux.org/viewtopic.php?pid=1608717#p1608717 in ArchLinux, and followed the steps   

1)I have replaced all binary files in both folders /lib/firmware/ath10k/QCA6174/hw2.1/ and /lib/firmware/ath10k/QCA6174/hw3.0/ for the files provided in this link;
2)made all binaries executables doing chmod a+x /lib/firmware/ath10k/QCA6174/hw2.1/* and chmod a+x /lib/firmware/ath10k/QCA6174/hw3.0/*;
3) created the file /etc/modprobe.d/ath10k.conf by doing "echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf";
4)restarted the computer;


Now both wifi and Bluetooth seems to works fine, although my dmesg output is still not clean

[vinicius@localhost Desktop]$ dmesg | grep ath10k
[ 5.413154] ath10k_pci 0000:02:00.0: enabling device (0000 -> 0002)

I dont know how relevant this is but my kernel has been updated to a newer version

[vinicius@localhost Desktop]$ uname -r
4.4.2-301.fc23.x86_64

although the problem has only been solved after executing all four steps enlisted above. Thank you all anyway.

Hi everybody,

I have sucessfully made my QCA6174 Wifi NIC working with the kvalo firmwares files on my Fedora 23 laptop.

I can connect to 802.11abgn Wireless networks but no to 802.11ac. I get the following error when I try in journactl : 

"kernel: wlp3s0: authentication with e0:ce:c3:ca:32:ad timed out"

Thank you all for your supports.
