Nintendo DS are already wi-fi enabled, there is no wi-fi addon. The Nintendo wi-fi adaptor plugs into a PC USB port.
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.
you cant
WiFi usb adapter is a WiFi card.
Yes, But if you have a cheap adapter then it will be slower.
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.
No you do not need wifi to go into the underground tunnles but you can use ds to ds action and play with your friends in the underground and trade and stuff.
NO
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.
No, the DS won't connect to the PS3.
Indeed-- If you have WiFi with a DSi you can go on the internet.
You need pay only for the adapter. If you have a wireless router you will not have to pay to anybody for your WiFi. But you still have to for Internet.
