QCA6174 not working in Ubuntu 16.04 after running upgrade yesterday

Question

I already had a problem with this before, and I was able to get it working using the drivers from: github.com/kvalo/ath10k-firmware/tree/master/QCA6174.

But after running Ubuntu upgrade (yesterday) I can't get the wifi connection anymore, I created a pastebin with the log of this here.

I have tried replacing the firmware again both with the kvalo and the FireWalkerX fork, with no result.

I also tried upgrading the linux-firmware:

sudo dpkg -i linux-firmware_1.158_all.deb

I'v also created a pastebin with the output of the wireless-info script recommended in the Ubuntu Forums, here it is.

sudo ethtool -i wlp5s0

Answer 1

I got it working with the help of a guy from Ubuntu Forums, here.

Here is the code:

sudo rm /lib/firmware/ath10k/QCA6174/hw3.0/*
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

And reboot.

Note that you need to download the board-2.bin and rename it to board.bin.
