I bought WiFiMAX first premium Bigben but this purchase proved risky because it did not work at all and the DS do not even recognize the connector. After canceling the sale I folded on the OFFICIAL NINTENDO connector impeccable walk him easy to install, although the DS recognizes the connector and can use wifi and download gifts or play online with other players around the world . For the same price as the WiFiMAX I rather recommend the Official connector ... If you ever have problems it is certainly because of your firewall. A purchase a counselor if you want to play with other players via wifi: Pokemon can be exchanges with the world and to obtain Pokemon that can not seem to find or just to complete his pokédex This is really great this connector!
