Hello, for some reason I get the error 20110: "Nintendo Wi-Fi connection service for this software has been discontinued" when I try to receive a pokemon. However when I try to connect into the GTS in the shiny² I got the message "This is a valid request". I'm using Pokemon Black 2 and a 3ds XL.

If this isn't the appropriate place please tell me but i think it is. I have Pokemon Black 2 and Pokemon X, i know that is possible insert the wondercard with the pokegen, but how is possible insert the wondercard directly into my pokemon black 2? is possible simulate a nintendo hotspot or something like that?
