can't get atheros ar2413 to connect under freebsd 7.2

[Atheer Elobadi]

hello,
I've been trying to set my wireless card under Freebsd 7.2-RELEASE, but no
success (it worked fine on 7.0).. would appreciate some advice


in /boot/loader.conf:

if_ath_load="YES"
wlan_tkip_load="YES"
wlan_scan_ap_load="YES"
wlan_scan_sta_load="YES"


in: /etc/wpa_supplicant.conf:

network={
     ssid="Myssid"
     key_mgmt=WPA-PSK
     psk="MySharedPhrase"
}


and in /etc/rc.conf:

ifconfig_ath0="WPA DHCP"


then i run    /etc/rc.d/netif start
it gives up....

** by the way.. ifconfig ath0 up scan    gives nothing..  not even an error
message.. what shall i do ??

thanks
