Given that wifi everyone is probably the first thing player try when they get the game, Nintendo is probably doing maintenance and upgrade right now. But it would help a lot of Nintendo sends a message and tell us exactly what's going on. Have anyone tried calling customer service?
Nintendo support site saids the disconnect error is due to high amount of traffics (not surprising). I would encourage everyone to fill out the survey to help Nintendo to solve the problem. http://www.nintendo.com/consumer/sys...s/gameSSBB.jsp
