Atheros open sources firmware for two wireless chips
Qualcomm Atheros has released the source code of firmware for two of its 802.11n wireless chips on GitHub. The source code and build tools for the firmware are released partly under the GPLv2 and and partly under the MIT license. The GitHub page provides build instructions for those wanting to compile their own firmware.
The firmware can be used for the stand-alone USB wireless chip AR9271 as well as the AR7010 chip, which is typically used combined with the AR9280 or AR9287 chips. Linux supports these components with the ath9k driver while OpenBSD users can access them via the athn driver.
