Why won't my DS work with WiFi?

Why does Wifi connection not work for your Nintendo DS but it works fine for your Nintendo wii?

• Answer:

  Actually, before I can answer, I'd like you to answer a couple of my questions. 1. Do you use a Nintendo Wi-Fi USB Connector? (If no, go to question 2) If yes, be sure that you have granted the DS permission to connect. 2. Does your access point use WPA? (if no, go to question 3) WPA is more secure than WEP or total lack of encryption, but the DS is incompatible with it. The Wii, however, is completely compatible. 3. Are you using a wired connection for your Wii? A wired connection on your Wii can't wok with your DS. because you need to connect you Nintendo-wi-fi usb connecter conected on the computer and then turn off firewalls then go to Nintendo wifi settings and press "connect to your Nintendo wifi usb connecter"and if it works try doing it again (well the button might say somthing sorta like that)
