Additional features

The chipset itself supports Atheros eXtended Range (XR) technology, and Atheros Super A/G (Turbo) modes, but this functionality may be disabled.

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.
