First of all, where can I find a nintendo USB connector and does it work with a wpa2 wireless router. I need to be able to get wifi on my ds games. 10 points for the best answer.
nintendo 3ds supports wpa2. :) just saying. the nintendo wifi USB connector looks like a flash drive, this device is use for those who doesn't have wireless router. you just need to plug it on your computer WITH an internet connection. (you use this because your computer is connected via ethernet(cable)). after you connect the nintendo wifi USB. Only your DS or Wii can detect the internet connection. Try looking on game shops :)
