Whenever I try to get an event Pokemon, or any mystery gift, the DS will say that the wifi-system's security settings are not supported by Nintendo. What's wrong?
Nintendo Wi-Fi Connection Support Page.
I read on the Nintendo Help Page somewhere that there are three types of Wi-Fi, it's like WEP, WPA and something else.
There is a certain type of Wi-Fi that isn't supported by Nintendo, don't know what it's called, don't really care either. Sorry. x3 So yeah, just venture through. x)
Hope I helped. :)
