i've installed Freya and everything is working nicely out of the box, except the WiFi.
My laptop has a Killer 1535, so i followed their instructions (http://www.killernetworking.com/support/knowledge-base/17-linux/20-killer-wireless-ac-in-linux-ubuntu-debian) and placed the content of kvalo's QCA6174 on my /lib/firmware/ath10k. My /lib/firmware/ath10k/QCA6174/hw3.0 content is:
board-2.bin
board.bin
firmware-4.bin
Since Freya uses a 3.x kernel i had to install the ath10k driver through backports. So i installed the linux-headers and the build-essential, downloaded backports and ran these commands:
make defconfig-ath10k
make
sudo make install
Everything went fine and the install told me to reboot. After the reboot the wireless icon appeared and listed my networks, but i couldn't establish a connection to them. After a few seconds they were not displayed anymore.
Then i've ran
dmesg | grep "ath"
Here's what i've got:

Now I'm kind of lost. Any idea?
sudo rm -r /lib/firmware/ath10k/QCA9377/hw3.0and then redownload from kvallo's github. With 4.5 kernel you could compare crc32 with bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1520343/…
