IPW2100 and "Failed to set PTK to the driver"

[mbuchhol at eu.uu.net]

Hi,

I have the Debian (Sarge) Kernel 2.6.6 with the IPW-Driver 1.0.1 and
wpa_supplicant-0.2.5

I use this configfile:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
network={
        ssid="UUnet"
        key_mgmt=WPA-EAP
        proto=WPA
        pairwise=TKIP
        group=TKIP
        eap=PEAP
        identity="logname"
        password="password"
        phase1="peapver=0"
        phase2="auth=MSCHAPV2"
        priority=2
}

This is the last message, before it starts over again:

WPA: Failed to set PTK to the driver.

I also found and activated encryption in the IPW-Driver's Makefile:

# If you do not want any encryption/decryptoin code in the driver,
# comment out this line:
CONFIG_IEEE80211_CRYPT=$(CONFIG_IEEE80211)



What have i forgotten to enable, define or install?
I have absolutely no clue and my manager wants to use my Notebook for a
presentation (that it works with Linux too) for a customer next
Thursday.
I already scanned the Mailing-List Archive, but could not find anything,
that matches.
Any help is welcome.

Thank you
