Get the latest ath9k driver
Any distribution shipping a kernel >= 2.6.27 will have ath9k present. Below is a list of the minimal distribution requirements to either use ath9k from 2.6.27 or from compat-wireless.
- Ubuntu Intrepid (8.10)
- Fedora Core 10
- openSUSE 11.1
- Mandriva Linux 2009.0 (formally known as Mandrake Linux)
- ARCH Linux
- Gentoo Linux
- Red Flag Linux 7.0 (based on Fedora 10)
If you want to get the latest ath9k driver you can get it by using the wireless-testing git tree. Read our git-guide for that. Alternatively you can simply upgrade only your Linux wireless subsystem by using compat-wireless.
To enable ath9k, you must first enable mac80211:
Networking ---> Wireless ---> <M> Improved wireless configuration API <M> Generic IEEE 802.11 Networking Stack (mac80211)
You can then enable ath9k in the kernel configuration under
Device Drivers ---> [*] Network device support ---> Wireless LAN ---> <M> Atheros 802.11n wireless cards support
Enabling bluetooth coexistance
You can enable bluetooth coexistance on ath9k by using the btcoex_enable module parameter. This is not enable by default as some devices have had issues with it.
modprobe ath9k btcoex_enable=1
