Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter

[holesovice]

I have a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter wifi card. It does not work with Linux Mint. But I now need wifi access....

Linux Mint 17.2 Cinnamon 64 bit

Have tried multiple fixes over the years but, nothing seems to fix the problem.
Any help would be appreciated.

Try this, in a terminal:

Code: Select all

sudo apt install firmware-b43-installer

Then reboot.

I just need to see what other hardware you have before recommending a fix

Looks like driver ath10k is not loaded, 17.x needs latest firmware: viewtopic.php?f=53&t=218281

[holesovice]

Thank you.

But sorry no.

I have tried multiple threads and this would just add to the mess.

That is road accident of a thread.

Linux MInt 18 is probably the easiest way, after booting into the install, do

Code: Select all

sudo apt-get install linux-firmware

Reboot

[holesovice]

Code: Select all

sudo apt install firmware-b43-installer

Been there done that. Sorry did not work.

[holesovice]

Linux MInt 18...

Yes.

I need to change/update my OS. But it is not an real option right now. That is a lot of work.
Not the install. But making backups, storing all the data, book marks passwords etc etc.

While it is the most valid option, it is not currently practical.

[JeremyB]

I don't think your graphics driver will work with the 4.4 kernel, so you would need to install the 4.4 backports and then create the firmware directory and copy the firmware in.

Backport install:

Code: Select all

wget https://www.kernel.org/pub/linux/kernel/projects/backports/2016/03/24/backports-20160324.tar.gz

Code: Select all

tar -zxvf backports-20160324.tar.gz

Code: Select all

cd backports-20160324

Code: Select all

make defconfig-wifi

Code: Select all

make

Code: Select all

sudo make install

Firmware install

Code: Select all

cd

Code: Select all

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.12_all.deb

Code: Select all

sudo dpkg -i linux-firmware_1.157.12_all.deb

Reboot

^^ That's neat because the linux-firmware in 17.3 Synaptic does not include QCA6174

Is https://github.com/kvalo/ath10k-firmware.git still updated?

[JeremyB]

It gets updated but some of the files might cause problems, and I think you still have to rename some files
