Hi.

I have an Asus V6V (V6800) laptop with Intel wireless adapter:
iwi0: <Intel(R) PRO/Wireless 2200BG

and FreeBSD installed:

defanbook# uname -v
FreeBSD 6.2-PRERELEASE #3: Mon Oct  9 17:40:59 UTC 2006

I want to connect to access point (cisco 350) with
hidden (not broadcasted) SSID using WPA/TKIP authentication
but still got no success.

Here is my wpa_supplicant.conf:

=======================
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

network={
        ssid="MY-SSID"
        scan_ssid=1
        key_mgmt=WPA-PSK
        proto=WPA
        pairwise=TKIP
        group=TKIP
        psk="PASSPHRASE"
        phase2="auth=MSCHAPV2"
}
=======================

Here is wpa_supplicant output:

Oct 09 18:24:52.082851: Cancelling scan request

As we can see, it just repeats specific and broadcast SSID scan
in cycle, but always says "No suitable AP found" and "SSID mismatch".
While this process is running I can see more and more
"Number of frames with a bad CRC receive" with the iwicontrol utility.

On another FreeBSD box with 6.1-release and same version of wpa_supplicant,
but with another USB wireless device (ural) all works fine.

Wireless connection in winxp on this laptop works fine too.

Any ideas?
