atheros 5211

Hi there,

I've a (probably) philips minipci wlan card with atheros 5211 chipset 
(a/b). However I loaded the if_ath.ko and my freebsd recognized it well, 
i can't make it work.
this means, i cannot make it associated to any access points, wether I 
set the ssid of accespoint or not. As a matter of fact, the led which 
shows the wlan radio set to on, is not active whatever I do in my 
freebsd. My card works well under other operating systems well.
I tried to make it work under freebsd 5.4 and 6.0 without any results.

any idea?
