iwi driver: ioctl[SIOCS80211, op 21, len 42]: Invalid argument

Hi

i am triing to connect Intel(R) PRO/Wireless 2200BG - iwi0 to WPA-EAP
wireless network with PEAP:

# wpa_supplicant -i iwi0 -c /usr/local/etc/wpa_supplicant.conf
Trying to associate with SSID 'OFFICE-PEAP'
ioctl[SIOCS80211, op 21, len 42]: Invalid argument
Association request to the driver failed
...

# kldstat | egrep wlan\|iwi
28    1 0xc0892000 2d08     wlan_wep.ko
29    5 0xc0895000 1ed74    wlan.ko
52    1 0xc4ff9000 7000     wlan_ccmp.ko
53    1 0xc5000000 4000     wlan_tkip.ko
54    1 0xc3828000 2000     wlan_xauth.ko
57    1 0xc4f36000 d000     if_iwi.ko
#

changing ap_scan=2 >> ap_scan=1
improves situation a bit, but still does not work:

...
