Linux Driver for Atheros 802.11 Chipsets

Support for the AR5210, AR5211, AR5212 and AR5213

 Intelligraphics has created a Linux station driver to support Atheros' 802.11 products. Developed to support kernel version 2.4.x and 2.6.x, these drivers have been based Atheros' own Windows driver code and support nearly all the features as the Atheros Windows* driver including:
  • 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
  • 802.11 Fragmentation Support
  • Supports Atheros Turbo Mode (108Mbps)
  • Supports 802.1h
  • WPA (May require customization for your Linux supplicant)

*There is not always a direct mapping of Windows OID calls to Linux 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.
