This card support IEEE802.11b/g and IEEE802.11a J52/W52/W53 frequency, but ath(4) driver does not support IEEE802.11a W52/W53 frequency. Notes: Wireless LAN formerly can not use W52/W53(36-64ch) in Japan. But due to departmental regulations changes, Wireless LAN can use W52/W53 after May, 2005.

But madwifi-ng at the beginning of November (with Debian GNU/Linux) can use IEEE802.11b/g and IEEE802.11a W52/53 frequency and can not use IEEE802.11a J52 (34-46ch).
