Not really like you could do that in the first place. I don't think anybody has a WEP Key anymore. So much so that back in the day, I went to The Macaroni Grill restaurant and while I was waiting for food, I played online games on Zelda: Phantom Hourglass. Good times.
For me, it said I needed to drop my internet security...most internet was wired back then (mine was anyway) so i never even got to use online on wii or ds :c
