I have a laptop with wi-fi access to my wireless router. I gave it a computer name of "Doug" so I would know if any one else gains access to my wireless system.
My SL-5500 also has a wi-fi card installed, but the only thing I can get to show up on my router is "unknown" when I access it from my Zaurus.
I have tried everything I can think of to change the computer name of my zaurus, but all I get is "unknown".
I would really like to name my zaurus so I have a good handle on access to my router.
I'm not sure if this will resolve the issue on your router or not. However, if you want the name of your Zaurus to show up on your PC, you need to add it to the hosts file, which is in C:\WINNT\system32\drivers\etc\hosts on Windows. For example, the line in my hosts file looks like:
192.168.129.201 zaurus
To give a name to the Zaurus, you use the "hostname" command like this:
/bin/hostname zaurus
However, that association doesn't survive reboots. To make the hostname assignment permanent, I added the above line to my /etc/rc.d/rc.local file, so it gets executed shortly after booting.
Aside: the best way to prevent other people from getting access to your router is to turn on MAC address control. That way, only WiFi cards that you specify can associate with your router.
