Networking :: How to setup WPA encryption?

Well, I was able to get a wireless Linksys card working using ndiswrapper.
Now I just need to encrypt.
I would like to setup WPA encryption, but I am not having any luck.

How can I set this up in DSL?

Download and install to MyDSL wpasupplicant_0.3.8-1_i386.deb from

http://fatboy/umng.edu.co/debian/pool/main/w/wpasupplicant/

Then follow the directions for making a wpa_supplicant.conf and starting wpa_supplicant using the WPA wiki from sourceforge
