wpa_supplicant: Problems associating with Cisco Arionet 1231

Hello!
While I have no trouble to set up a WLAN connection at Home and some
other locations, I'm unable to connect to the WLAN at work. We're using
a 'historical' setup with WEP in combination with VPN.
My system:
Debian unstable/testing with homemade (vanilla) kernel linux-2.6.18,
patched with ieee80211-1.2.15, suspend 2 and with the ipw2200-1.2.0 modules.
I'm using a roaming setup with wpasupplicant (0.5.5-2), ifplugd (0.28-2)
and guessnet (0.41-1). The setup works fine for my network at home
(cable and WLAN with a Linksys WRTG 54G router).
/etc/modprobe.d/ipw2200:
options ipw2200 associate=0 led=1 hwcrypto=0 debug=0x43fff
'iwlist eth1 scanning' gives:

According to my colleagues, this is only one physical access point
(Cisco Arionet 1231).
wpa_supplicant.conf (other networks removed):
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
# wlan at work
network={
ssid="tsunami"
id_str="uni_wlan"
key_mgmt=NONE
auth_alg=SHARED
wep_key0=nottosay
wep_tx_keyidx=0
}
/etc/network/interfaces (only the WLAN part):
auto eth1
iface eth1 inet manual
wpa-driver wext
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface uni inet dhcp
I've removed other WLAN definitions for debugging.
If I remove the eth1 part from /etc/network/interfaces (or tell ifplugd
not to use eth1), I can associate after reboot to the accesspoint
manualy with
'iwconfig eth1 essid tsunami key donotsay'.
With the roaming setup, association is impossible. I've also tried to
associate to the accesspoint with wpa_supplicant:
'wpa_supplicant -ieth1 -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf -dd'
There are a lot of state changes between ASSOCIATING/DISCONNECTED in the
output. I've tried different locations with varying signal strength with
the same results.
To me it looks like a problem with wpa_supplicant and this type of
accesspoint, because I made the same SSID/Key setup at home, where I had
no problem to connect to the accesspoint.

I've attached /var/log/debug for the initialisation of the driver
and firmware. I've also attached /var/log/debug for both manual and
roaming association attempt and the output of wpa_supplicant.
ipw_init.log /var/log/debug, driver init
ipw_manual.log /var/log/debug, manual association
ipw_supplicant.log /var/log/debug, with wpa_supplicant
wpasupplicant.log output of wpa_supplicant
I get a lot of 'excluded because of storming' messages and I see
'ipw_rx_notification AUTH_SEQ_1_FAIL' in the log. Help would be appreciated.
Thanks,
Berthold
