Connect to nintendo wi fi!
Ok... so what u can do is.... Go to Nintendo Wi Fi or multiplayer. Go to nintendo Wi fi Go to configure....

Then, at settings, press the blue button, then, in wireless connections (not aoss or connect to ur nintendo wi fi connector) the DS will search for wireless connections.... If there is a connection with a blue lock you are ready to go! (select it) (Make sure you -*test*-('") the connection, after u select it, and ur nintendo DS says connection sucssessful!!!) If there is not any connections at all or connections with red or grey locks only, then you should consider buying a nintendo wi fi usb connector 39 dollars without tax (USA) This thread is for the ones who need instructions.....
