Comment 22 for bug 1520343

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

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

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

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.
