Review of Linux Compatibility

The TP-Link TL-WN722N is a USB WiFi adapter. The identical USB stick is also available together with a cradle, but under the ID TL-WN722NC. The USB stick has the USB ID 0cf3:9271

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

and is supported under Linux by the kernel module ath9k_htc. This module is part of the wireless drivers of the Linux kernel. If the driver is not already part of the used Linux distribution it can be downloaded separately and compiled by hand:

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

The TL-WN722N needs two firmware files in order to function. These files can be downloaded from http://wireless.kernel.org/download/htc_fw/1.3/. There, one finds the two files htc_9271.fw bzw. htc_7010.fw which are needed for the chipsets AR9271 and AR7010 of the TL-WN722N. These files must be copied to /lib/firmware to be found by the kernel and have them loaded automatically during the initialization phase of the driver:

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

  • mike says:

    make doesn’t work!!! the last error is as follows:

    make[1]: Leaving directory `/usr/src/linux-headers-3.14-kali1-amd64′
    make: *** [modules] Error 2

    you need to fix this!

    • Hi Mike

      First: do you really need to compile a new kernel module? because normally the ath9k_htc should be part of your distribution’s kernel already.

      Second: the compile error is not very helpful since the important part is missing. Please paste all your output e.g. to http://pastebin.com/ and leave us here a link to the output. Did you install the necessary kernel headers before trying to compile the driver?

Please use the comment section to submit corrections to the article as well as relevant excerpts of lspci, lsusb, lshw, dmesg e.t.c. Furthermore, use the section for the exchange of experiences with this hardware component or search for configuration help from other owners of this hardware.
