I bought mario kart ds, and you can play wi-fi. I have a Sweex router LB200010 (wireless). My Nintendo ds will find in the search for an access point or router, then I enter the web key and then I have no connection.
My Nintendo ds gives the error 51300: "Unable to connect to an access point.
I have confirmed Nintendo WFC connection settings and access point settings.
I have everything already in place manually, but unfortunately that helped too.
Could someone help me, thanks.
