Solution 1:
For Ubuntu 16.04 users: Do not use the dkms or backports, you just need to install firmware and set the parameter using
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb
sudo dpkg -i linux-firmware_1.158_all.debReboot
For Ubuntu 14.04 and 15.10 you need backports and firmware
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz
sudo apt-get install build-essential linux-headers-generic
tar -zxvf backports-4.4.2-1.tar.gz
cd backports-4.4.2-1
make defconfig-wifi
make
sudo make install
dmesg | egrep -i 'ath|firm
Edit to add:Firmware Install
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb
sudo dpkg -i linux-firmware_1.158_all.debEnd of Firmware Install
If you get a new kernel, your wireless will quit working until the new kernel contains the fix, if you notice wifi isn't working after a reboot
cd backports-4.4.2-1
make clean
make defconfig-ath10k
make
sudo make installReboot
