Please try with a temporary internet connection:

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -zxvf backports-20151120.tar.gz
cd backports-20151120
make defconfig-ath10k
make
sudo make install

Reboot. It will probably be missing the required firmware. Please find out and post:
