hi  experts:
I think the hardware is ok because I can use it in Win7. And in Freebsd
9.1,it works for sometime,but sometimes after system reboot or I plug out &
plug in the card it my unusable.on the console it emmit:
 "run0: wcid=xx out of range" where xx is 91,87 and etc.

it seams the wifi is connected because ifconfig wlan0 cmd shows the right
ssid and bssid ,but inet addr is always 0.0.0.0

would you please help me?
