I seem to be having troubles setting the Wifi for my DS and it is getting frustrating.

I have a Realtek RTL8187 Wireless Router and a DS Lite. I tried following the instructions on nintendowifi.com but unfortunately, I am still unable to use Wifi features for the Pokemon and Digimon games.

Can anyone give me a step by step Idiot's Guide on how to set it up. I just recently purchased this and setting the PSP's Wifi connection is much easier than this.

Thank you to those who are going to help.

This is also urgent.
