Wifi Passwords for Nintendo DS

This is my first thread, and yes, it's a question! I can't remember the ASCII password for my wifi network, but I have the HEX one. I can't seem to be able to convert from HEX to ASCII without getting a nonsensical string of characters. Does anyone know of a way to get my password in HEX? The DS only accepts keys of up to 24 (if I remember), so what do I do?

Why aren't you googling now ? I hope you will get answer in their official site.....
