How to configure WIFI on GPE

[pisiiki]

I have spent a lot of time trying to configure the wifi on the GPE linux, I have very little experience with linux and I really don't know how to setup the adapter. My network is a B/G with DHCP and 128 bit WEP. I have set the data on a configuration tool but it doesn't seem to work. Can someone help me?

I installed openmoko. For surfing the web i do:
- Open terminal
Code:
ifconfig wlan0 up
iwlist wlan0 scan
iwconfig wlan0 essid "my-essid"
ifup wlan0
Note: i don't use encryption, you can try: "iwconfig wlan0 key open (WEP-KEY)" after setting the essid, don't know if wep or wpa is supported.
Now i open the webbrowser and surf the web.
The resolution 640x480 is a pleasure but because of starting from sdcard the browser is slow.
