I just tried to connect to a Mario Kart game with Willz, but it won't even pick up a Wireless signal.
I checked the settings and it won't allow me to connect in Mario Kart DS, but it will allow me to connect to Wifi in Pokemon Pearl. I'm using the same DS and the same settings.
Is there something that I need to do/change so that I can connect to Wifi in Mario Kart?
I'd appreciate some help.

Are you in range?

Set up your wireless internet again. Check your Wi-Fi settings again. This has happened to me once, but after I reset everything, it worked out fine.
If it still doesn't work,
try connecting with pkmn again
if this doesn't work, you probably need to turn off all your computers, routers, modems, etc, wait a couple of minutes, and then start everything up one at a time.
If everything fails, and pkmn can connect, then the most likely problem is something on nintendo's end
(maybe :bored

Alright children (xD), I just got off the phone with Nintendo. After following their step by step instructions, Mario Kart is picking up the wireless signal.
However, when I try to connect to Wifi, it says that the Wifi Connection ID and the Game Card ID (Or something to the caliber) do not match. I'm asuming it thinks I'm using someone else's game card, though I'm using my own.
I think that I cleared my Wifi records and Connection ID.. How would I go about fixing this? >.<
--Edit--
Ahahaha. It works now. ^_^
Yay for Barbara from Nintendo. She's helped me twice. Definitely ask for her. xD
Riku/Other Mod, mind closing this? Thank you.
