Misc Can't play online

[Ka-Wing]

Why can't I play online with Mario Kart and SSBB?
Everytime I try to connect, it will work.
but if I try to play or something, it will disconnect.
What is the problem?

The firmware of my wii is 3.4E and I've installed the gamma backup launcher 0.3 beta

The connection test does not always mean that you are ready for online gaming. Check your router's settings and make sure that you have the same WEP, or it is an open connection(not suggested but works anyway). You can also erase the saved connection and try to reconnect. That's what I do if I have any problems.
