How come I cant play online against other people with my R4? I try to play Mario Kart DS and Metroid Prime Hunters, even Pokemon Diamond. When I go to WiFi settings and enter in the information, the test doesnt pass..its ends up with an error. Can someone help me out.
Be more descriptive when asking for help online. If you note the error code and search the nintendo site, or even google, you will find a list of things you can do to troubleshoot the problem.
