Well, I've never connected it to wifi. My 3DS can connect to our wifi; I'm using it. For some reason, though, WW is trying to connect to wifi on it's own using a regular DS connection, not the 3DS wifi connection. I have no idea what my wifi's WEP key is, so therefore I can't use it on a regular DS, as my 3DS only required the regular password you would input in your phone or whatnot. Meh.
