FreeBSD 6.2 configuration PRO/Wireless 2200BG

[Jean-Christophe]

Hi,
I try to set my wifi up on my laptop (Asus W6A).
My AP is a livebox inventel (software version v5.10.7-fr).
I use WPA encryption and i don't find the DHCP proprieter for the
wireless.

I try to connect with WPA security and without security but whaterver
configuration i have in my ifconfig :
"status: no carrier"

this is my last config file :
