Problems: associating ipw3945 wpa_supplicant

Hi all!

Short description: I found an AP which I cannot associate to at all. All
other AP in my surroundings do work without problems.

hardware: ipw3945
software:
kernel 2.6.20
ipw3945 1.2.0 (latest)
(also tried with iwlwifi svn checkout)
wpa_supplicant 0.5.5
debian/sid

The AP is the only configured in the wpa_supplicant.conf file:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=2	# also tried with =0 and =1

network={
	ssid="Hotel NoName"
	key_mgmt=NONE
	auth_alg=SHARED
	wep_key0="5570441089532"
	wep_tx_keyidx=0
	priority=3
}

With the same configuration (well with some more networks) y laptop
associates without problems to various AP (home, university, internet
cafe), only this one does not work atall.

It seems that it is associated:
wireless  unassociated  ESSID:"Hotel NoName"  
          Mode:Managed  Frequency=2.437 GHz  Access Point: 00:04:0E:95:B3:37   
          Bit Rate:0 kb/s   Tx-Power:16 dBm   
          Retry limit:15   RTS thr:off   Fragment thr:off
          Encryption key:3535-3730-3434-3130-3839-3533-32   Security mode:restricted
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:7   Missed beacon:0
But no conection, no response, and disassociating ...

I started wpa_supplicant with -dd and captured the output, it is
attached

Thanks a lot for any suggestions and ideas what else I could do to get
it working.

One more data point: With WindowsXP on my laptop and with my Palm T|X it
is working without any problems

Thanks a lot and all the best

Norbert

the castle the squires attempt to raise the drawbridge very suddenly
