FreeBSD Driver for Atheros 802.11 Chipsets

Support for the AR5210, AR5211, AR5212 and AR5213

Intelligraphics has created a FreeBSD station driver to support Atheros' 802.11 products. These drivers have been based Atheros' own Windows driver code and support nearly all of the same features:

  • Support for both Adhoc and Infrastructure modes
  • Support for 64/128 WEP

    •      WEP Key Table Management supports addition and update of keys

  • 802.1x Authentication
  • 802.11 Roaming

    •      Based on signal strength/retry statistics
         Functions with scan/join state machine code

  • Rate Adaptation

    •      Supports automatic (best supported) rate adaptation with automatic rate fallback after excessive
         retries

  • 802.11 Power Management

    •      Supports Beacon TIM/DTIM processing
         Supports NULL data frames to AP
         Supports PS-Poll transmission

  • 802.11 Fragmentation Support
  • Supports Atheros Turbo Mode (108Mbps)
  • Supports 802.1h
  • WPA (May require customization for your FreeBSD supplicant)

*There is not always a direct mapping of Windows OID calls to FreeBSD IoCtl calls and so we have implemented the most important ones. If a feature that you require is not listed, then it can most likely be implemented very quickly by adding the appropriate IoCtl call.
