Install Wireless USB Adapter TL-WN721N driver on Ubuntu 10.4

Hello Folks,

This last weekend and I have to play a little bit with Ubuntu 10.4 and my new wireless USB adapter TP-LINK model TL-WN721N. The Ubuntu 10.4 has not recognized the adapter, so I had to ask Google how to make that works. I’ve tried many things, one was using diswrapper with Windows Driver, but did not work. After another attempts I found a solution, and I decide to write here.

The first step is to get the firmware, you can download it from the following link:;a=blob_plain;f=ar9271.fw;hb=35b308409dc18991ec833c24972fd631c9f479a1

After the download you need to copy it to /dev/firmware directory:

sudo cp -r ~/Downloads/ar9271.fw /lib/firmware

Now we need to get the latest version of compact wireless, you can get it from the link below:

I got the file compat-wireless-2.6.tar.bz2

After the download you will need to uncompress the file:

tar -xjvf compat-wireless-2.6.tar.bz2

Now, it’s time to compile the driver. Enter in directory:

cd compat-wireless-2010-05-23/

and type the command:

sudo make

After the compilation, you can install the driver using the command:

sudo make install

Now, you need to unload the old driver and load the new one:

sudo make unload
sudo make load ath9k_htc

After loading the new driver you must reboot you system and once the system rebooted you will be able to use your wireless connection.

I hope this tip will be useful for you.

See you!!
