Supported chipsets

  • AR6003: It is the third-generation Wi-Fi chip from Atheros optimized for the throughput, size, and energy efficiency needs of mobile and embedded devices. With its tiny footprint and energy-saving qualities, the AR6003 rounds out Atheros™ comprehensive Align® ecosystem of 1-stream 11n solutions, targeting smartphones, mobile gaming and portable CE devices.


This driver is upstream as part of the Linux 2.6.37 release under the staging area. From Linux 3.2 onwards it was promoted from staging to a proper wireless driver.

It is also available for older kernels through the stable compat-wireless releases.

Hacking on ath6kl

ath6kl is now part of wireless kernel trees. All the development happens in github github's ath6kl project. To clone the tree:

git clone git://

The driver is located in drivers/net/wireless/ath/ath6kl. To compile the driver enable CONFIG_ATH6KL which is found under Device Drivers/Network device support/Wireless LAN/Atheros Wireless Cards/Atheros ath6kl support. Also enable CONFIG_ATH6KL_DEBUG to include all debugging code.

Send any patches to Kalle Valo <>, CC linux-wireless and <>. To learn more about git you can refer to our Git guide. It even documents how to send patches with git format-patch.


For technical support send email to <> and CC <>. Due to lack of time the ath6kl developers are not able to give private support, so please send all questions to the mailing lists.


We have an IRC channel with some of the ath6kl people.

IRC server:
IRC channel: #ath6kl

Please take into account the different timezones and schedules, it might take a long time to get an answer.

Note: Windows boxen by default seem to block IRC ports so go find yourself a Linux box ;)


Get the firmware from linux-firmware.git.
