Ive been trying to access online features with my acekard 2i in a few different games, but they never connect im using a 3ds on the latest firmware if that helps. More recently i just tried with pokemon conquest but i cant connect for some reason, I know i have the 3ds connected to my wifi too, hell i even tried changing the security from WPA to None
Online should work fine, it's likely some router settings or something, DS stuff seems to be pretty picky. Try the troubleshooting steps on the nintendo site.
