It needs wifi.
Every single ds, ds lite, dsi, and dsi XL comes with built in wifi. To get to it, you have to have a wifi compatible game, and there will be wifi settings somehwhere on the game. You have to edit the settings. But i cant help you there. :)

What can detect your DS? Please be more specific. From what I gather, your saying that the Nintendo WiFi USB Connector (WiFi USB) can dtect your DS but not your DS cannot detect 'it'. WiFI USB cannot detect Nintendo DS's unless it is connected to it. So, the Nintendo DS would have to be able to detect the Wifi USB for it to be able to detect the DS. ThE AvEnGeR
