[ath10K] QCA6174 firmware

[John Detter]

Hello everyone,

I recently bought a laptop (Samsung) that has a Qualcomm Atheros QCA6174 
card. I have tried using the firmware from both kvalo's repo and the 
official linux-firmware repo and neither of them have worked. I am 
running a fresh Ubuntu 15.10 installation (Linux 4.2.0). I have also 
tried installing Ubuntu Gnome 15.10 with the mainline kernel build 
(Linux 4.4.0) and that didn't work either. The laptop I'm using does 
have a button on the keyboard to enable/disable the wifi and I'm not 
sure if it's causing an issue or not. I have checked rfkill list and 
there is neither a hard nor soft block on the wlan. I'm not really sure 
where to go from here, any help would be much appreciated!

Thanks for your time,

- John
