WLAN setup in Zaurus (Discoverer application.)

Hi all.,
I have a Sharp Zaurus device SL-5000 ROM 1.13 , DLink DCF-650W NIC.
i installed wlanmon (Wireless Lan Monitor)application. It displayed,
signal -27
noise - 27
quality - 0
However,
    I installed discoverer on my device and in the configuration panel 
clicked etho and selected prism2.
    In the status panel got the message as ok.
    but i was unable to see any display in the main panel. not even the 
SSID. Any work arounds for this.

regards,
prabagar.
