Ipw2200 driver unstable...

Hi everybody,
I have an IBM Thinkpad T43P with an Intel/Pro Wireless 2915ABG Network 
Controller.

I have installed Debian GNU/Linux Etch, with a custom kernel v. 2.6.15
I have downloaded the ipw2200-1.1.2, the ieee80211-1.1.13 drivers
and the ipw2200-fw-3.0 firmware

I have also installed wpasupplicant 0.4.8-4

I have check all prerequisite, but my wireless network is very unstable :-(
Very rarely it works for some second ones .

These are the ouput:

This is my wpa_supplicant.conf file:
update_config=0
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

network={
        ssid="Marco's Test Wi-Fi Network"
        scan_ssid=1
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=TKIP
        group=TKIP
        psk="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
        priority=10
}


When rarely works these are the output:

I have also installed this patch
http://sourceforge.net/mailarchive/message.php?msg_id=15309282
but my network is still very unstable :-(

I have also try with ipw2200-1.1.0 driver but also this doesn't work.

Could you help me?
Thanks

Marco
