Additional features

The chipset itself supports Atheros eXtended Range (XR) technology, and Atheros Super A/G (Turbo) modes, but Firmware disables the functionality of SuperG/XR. No Registry patch available

Linux WiFi driver

This is an Atheros chip and works with the Madwifi driver "out of the box". This card will be also detected by open-source ath-driver, but as of now (end of January '06), it doesn't support actual wireless operations.

Make sure that your kernel supports "CONFIG_SECURITY_CAPABILITIES", or you might get some message from the Atheros hal that it does not support all features.
