ath9k is a completely FOSS wireless driver for all Atheros IEEE 802.11n PCI/PCI-Express and AHB WLAN based chipsets.

You should subscribe to this page so you can get e-mail updates on changes and news for ath9k automatically. You'll get an e-mail as soon as this page gets updated.

Our mailing list for this driver is:

Any distribution shipping a kernel >= 2.6.27 will have ath9k present but the ath9k driver on 2.6.32 is the oldest one recommended, anything older than that is completely unsupported.

The latest ath9k driver can be obtained from backports.

To enable ath9k, you must first enable mac80211 through make menuconfig when compiling your kernel. If you do not know what this means then please learn to compile kernels or rely on your Linux distribution's kernel. Below are the options you need to enable ath9k through make menuconfig.

Networking -> Wireless -> Improved wireless configuration API Generic IEEE 802.11 Networking Stack (mac80211)

You can then enable ath9k in the kernel configuration under

Device Drivers -> [*] Network device support -> Wireless LAN -> Atheros Wireless Cards -> Atheros 802.11n wireless cards support

SB = single-band 2.4GHz DB = dual-band 2.4GHz or 5GHz

  • When it went in

    ath9k was announced to have been merged into Linux-2.6.27-rc3 by Linus on Tue, 12 Aug 2008 19:33:16 -0700 (PDT), and consisted of 58.8% of the entire rc3 patch.

    Early distributions which picked it up

    OpenWrt became the first distribution to pick up ath9k and contribute to it.
