Ya, I know. DS games also cant use WPA on the 3DS.
@Soulx are you sure your just not full of BS?
My my, you are quite stupid. You just don't know when to admit you're wrong.
I guess the hundreds of other people online are full of BS, too.
Let's break this down.
Black White is a DSi game, correct?
DSi games can use WPA/2, correct?
Okay. So far so good.
If he has a DSi or a 3DS, if you use a legit cart you can connect.
If he has a DS Lite, you can't connect to WPA/2 no matter how hard you try
Also if he has a 3DS or DSi and is using a flash cart, it still would not connect because that aspect of DSi mode isn't implemented in that particular flash cart.
Find your situation above to figure out whether or not this thread is worth continuing.
