well, my wifi works at home. However, I can't make it work in my office. Because the ssid is something like "4th floor", and I can't type space. How can I solve the problem?
I can't remember if the 802.11 spec allows spaces in the SSID or not, but the fact is that many (all?) access points support it.
To enter an SSID with a space in the Zaurus, use the Network Settings Applet and create it without the space. Then using an editor, such as vi (but not TextEdit), edit the corresponding entry in /home/etc/pcmcia/wlan-ng.opts.
The network entry will look like:
YourNetworkConfigName,*,*,*)
...
DesiredSSID="SSIDname"
