Wifi dose work on Nintendo ds but you have to be in a place that has free wifi and it also depends on if you have a game that uses wifi.
Here are some suggestions of places that should have wifi star bucks, some safe ways may have it, or you can buy it for about $15 a month and up. good luck
Yes
It needs wifi.
yes it does
if wifi means connect with other players than it aready has wifi
No, as it uses local WiFi connections.
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
You get it automaticly in the DS

Yes. All versions of the Nintendo DS have Wi-Fi.
Yes

Indeed-- If you have WiFi with a DSi you can go on the internet.
Yes, you need the Nintendo DS WiFi USB adaptor to access the internet.
for ds and ds lite get a game with wifi connection and select the wifi setup, then search for an access point on one of the three slots. You have to have wireless internet to do this, or the Nintendo wifi adapter, which is kinda crappy.

Yes all Nintendo DS's no matter what the version have the abilty to receive WIFI.
