Note that I confirmed following solution works on linux 4.2; perior kernel may not works.

This is how I accomplished:

  1. Download firmware: https://github.com/makerj/ath10k-firmware/archive/master.zip
  2. Unzip archive
  3. WE NEED board.bin, firmware-5.bin_SW_RM~ which placed at QCA6174/hw2.1. thus, copy directory from ./ath10k-firmware-master/QCA6174 to /lib/firmware/ath10k

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

  4. Remove any suffix from firmware file. (e.g. firmware-5.bin_SW_RM~. to firmware-5.bin)

  5. Reboot

Code version:

wget https://github.com/makerj/ath10k-firmware/archive/master.zip
unzip master.zip
cd ath10k-firmware-master/
sudo cp -r QCA6174/ /lib/firmware/ath10k/
cd /lib/firmware/ath10k/QCA6174/hw2.1/
sudo mv firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 firmware-5.bin
sudo reboot
