As Nintendo has discontinued their sale, you're best off looking for one on one of many online auction/sale sites such as eBay or Craigslist.
sorry for the WNR2000v3
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.
No it can not. The Nintendo wifi usb adapter sends a signal that only Nintendo products meant to connect to wifi (such as the DS and the Wii) can pick up. Xbox and other products of that nature can not pick up on the wireless signal sent out by the usb adapter.
Nintendo wifi is a free service to all wii and ds users all though it depends on what kind of internet you have if you don't have internet that can support Nintendo wifi you will need to purchase a wifi adapter.
Nintendo DS are already wi-fi enabled, there is no wi-fi addon. The Nintendo wi-fi adaptor plugs into a PC USB port.
There is a wi-fi USB internet adapter available for the Nintendo DS.
no
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

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