Nice to see someone still plays AC:WW. I wish I could play. Sadley my router has a WPA2 Encrytion and the Nintendo DS can only support upto WEP encrytions. As for the 3DS, the 3DS does support WPA-2, however, when you play a DS game on the 3DS you have to set up a DS connection to wifi, and it uses the same software as the Nintendo DSs.
