WPA: No encryption reported

Mon Sep 5 04:44:40 PDT 2005

I am sorry for the delay.  

The problem again: wpa_supplicant sees the access point but fails to  
detect WPA encryption.  

The facts at a glance:  
  iwlist scanning: reports encryption present 
  Windows connects to the AP with WPA encryption (PSK, TKIP).  
  Linux with RaLink-based (rt2500) card connects to the AP with WPA.  
  wpa_supplicant fails to see encryption: 
    5: 00:03...:ca ssid='wolke' wpa_ie_len=0 rsn_ie_len=0 
      skip - no WPA/RSN IE 

Any suggestions what could be done? 

Regards, 
Wolfi 

Here is the complete setup:  

It is a laptop with an ipw2200-based card. Non-encrypted links work  
nice under linux. The other side is a linux-based T-Sinus DSL modem/ 
router
