Tip: You can then merge these driver modifications into the Linux source tree for your distribution-provided kernel version, in order to improve compatibility. On Ubuntu, run:

UBUNTU_KERNEL_TAG=Ubuntu-3.13.0-32.57

Modify the line above with your Ubuntu kernel tag. First, determine your full kernel

version by reading /proc/version_signature; then, look up the Ubuntu kernel tag at:

http://people.canonical.com/~kernel/info/kernel-version-map.html

. /etc/lsb-release git clone git://kernel.ubuntu.com/ubuntu/ubuntu-${DISTRIB_CODENAME}.git git checkout ${UBUNTU_KERNEL_TAG}

use the repo replace the ath9k dir(ubuntu-trusty/drivers/net/wireless/ath/ath9k)

cd ubuntu-trusty

compile

make -C /lib/modules/$(uname -r)/build M=$(pwd)/drivers/net/wireless/ath/ath9k modules

install module

cd /lib/modules/3.13.0-32-generic/kernel/drivers/net/wireless/ath/ath9k for file in ./.ko; do sudo mv $file $file.orig; done cp ubuntu-trusty/drivers/net/wireless/ath/ath9k/.ko . sudo modprobe *.ko sudo depmod sudo reboot
