hi same pb, you need to edit
1 - the WLANx.conf in /home/zaurus/Applications/Network/modules there are several one if you have set up several connexions. you will find a field with your ssid, add a space.
2 - and in /etc/pcmcia/wlan-ng.opts, you will find all your set up. find your ssid to be modied and add a space.
.. for me something went wrong with the dhcp, i had to set up a fixed IP, mask, gateway first (my laptop was connected, i just get the gw and mask from it and add 1 to the laptop IP for the Z), then after that the connexion was succefull but no access to the the internet. I removed the fixed stuff, and this time the dhcp process was ok, and it is working.
