Is there a downloadable GUI out there for setting up wireless with WPA encryption? I use Damn Small Linux the most, and setting up WPA is a really bugbear for me.

Thanks!

NetworkManager would be cool, but I'm not sure at all that you can get it's functionality without having a big desktop with a panel applet to sit it into. Gnome comes with it, but Xfce doesn't as far as I know, and that has bugged me too

But setting up WPA encryption is not a big deal. Just get familiar with wpa_supplicant configuration file; in the easiest case (which means often) you'll get away with less than 10 lines in that file, and a wpa_supplicant command with a couple of arguments along with a dhcp client command (unless you use static ip). You can even use wpa_passphrase to generate a basic network entry to add to the configuration file; the rest you can find out by reading the manual page of that configuration file:
See the examples for a start.

Once it's done,
and you're done. Change arguments if needed to suit your environment.

Note: you don't have to touch the configuration file of wpa_supplicant after it's done the first time, and for the wpa_supplicant startup you can create a nice script and maybe even run it in the boot scripts to have it work automagically. It's a lot easier than it looks like

Yeah, I know. I know! But I'm dumb. I've tried, oh LAWD how I've tried, but I haven't been able to get WPA_supplicant to work properly. ;-)

The problem I THINK I keep running into is write permissions with DSL.
