How to deploy TL-WN722N in Ubuntu 14.04 Back
Driver Installation
Part I
Install all the dependencies in need:
sudo apt-get update
apt-get install gcc build-essential linux-headers-generic linux-headers-`uname -r`
Part II
Download backports-3.16-1.tar.gz and unzip it:
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.16/backports-3.16-1.tar.gz
tar xvfz backports-3.16-1.tar.gz
Enter the uncompressed directory and clean build area:
cd backports-3.16-1 && sudo make clean
Build and Compile:
sudo make
If you have met some error while compiling, following these instructions to specify the driver you want to build and install by running the following command and make again:
sudo make defconfig-ath9k && sudo make
If there is no error, then install:
sudo make install
Part III
Load drivers at boot time:
echo "ath9k" | sudo tee -a /etc/modules
echo "ath9k_htc" | sudo tee -a /etc/modules
Edit rc.local:
# sudo vim /etc/rc.local
# use `lsusb` to check the usb device id of your TL-WN722N
# add the following two lines into the file
# Declare TP-WN727N USB ID to ath9k_htc module
echo "148F 7601" | tee /sys/bus/usb/drivers/ath9k_htc/new_id
exit 0
Part IV
Finally, the script mentions something about updating your initramfs. It might not be needed but these are kernel modules so that's what we will do by running the following command:
sudo update-initramfs -k all -u
and don't forget to update grub when you are done:
sudo update-grub
After all have done, all should take effect after reboot the computer.
Switch to TL-WN722N from the built-in wifi
Add the following line to /etc/network/interface:
# sudo vim /etc/network/interface
iface wlan0 inet manual
and run the following command:
sudo service network-manager restart
