Atheros releases driver for 802.11n USB sticks

Atheros has just announced the release of yet another Linux driver for their equipment:

We would like to see our Atheros 802.11n USB Linux driver upstream however we need help with this so we are releasing our Atheros 11n USB Otus Linux driver under the ISC to the community. The goal is to work with the community to help move this forward upstream. We are hoping for community help and leadership on this (*cough*).

In the meantime users should be able to use this driver and patches are welcomed to add newer wireless extension support so users on newer kernels can get their devices working. The focus should be upstream though :)

Otus, as the driver is called, supports all current 802.11n USB chipsets of the AR9001U family (UB81, UB82, UB83). It currently works with 2.4 and 2.6 kernels (up to 2.6.24). Implemented features are:

  • IEEE standard compliance
  • IEEE 802.11a/b/g
  • IEEE 802.11h, 802.11d
  • IEEE 802.11i
  • IEEE Draft 2.0 802.11n
  • Ad Hoc:
    • join (2.4GHz, 5GHz if SKU allows)
    • create (2.4GHz , 5GHz if SKU allows)
    • Adhoc security: WEP
  • Security.:
    • Authentication: WPA/WPA2 (Personal / Enterprise)
    • 802.1x Encryption: none, AES, TKIP, WEP40, WEP104

In order to support the effort of bringing this driver into the Linux kernel, we have created the otus-devel mailing list as place for developer discussion.
