Review of Linux Compatibility

The TP-Link TL-WN722NC is a USB WiFi adapter including a docking station. The identical USB stick is also sold without the docking station, but under the nameTL-WN722N. The USB stick has the USB ID 0cf3:9271

Bus 001 Device 003: ID 0cf3:9271 Atheros Communications, Inc.

and is supported by Linux via the kernel module ath9k_htc. This module is part of the kernel’s wireless driver package. If it is not already included in the used distribution it can be downloaded and compiled:

wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
tar -jxvf compat-wireless-2.6.tar.bz2
cd compat-wireless-2012-04-26/
./scripts/driver-select ath9k_htc
make
make install

A firmware file is necessary to use the TL-WN722NC. This file is available at http://wireless.kernel.org/download/htc_fw/1.3/. There, on can find the files htc_9271.fw and htc_7010.fw which are needed for the chip sets AR9271 and AR7010 of the TL-WN722NC, respectively. These files have to be copied to /lib/firmware. Afterwards, the kernel can automatically initialize the drivers if the TL-WN722NC is plugged in:

ath9k 0000:05:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
ath9k 0000:05:00.0: setting latency timer to 64
