You check the menu!
yes think you can
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. :)
yes it does
if wifi means connect with other players than it aready has wifi
Yes, if there is no security (password) or the security is WEP.
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.
Nintendo wifi is a feature only available with the Nintendo wii and Nintendo ds/ds lite/dsi. the basic idea is that you connect to the internet and play games. heres how to get connected: you need- a wireless router, a broadband high speed connection, a ds/ds lite/dsi, and a wifi game. once you have got all these things, simply set your wifi settings-should be an option in the game- and then get connected!
On a DS lite you can change the lighting on the screens so they're lighter or darker. On the DS there is no way to change the lighting. If you get a DS or DS lite I would recommend the DS lite. It is handy because you can see it better in all different lighting.
you have to go to a place with wifi like toysrus
Yes you can. You can also connect DS lite to DS and DS Lite to DSi.
on a ds at the back it does NT ssay ds lite and on a ds lite it says ds lite
All you need is a wireless router, the kind that lets any laptop or PC use wireless internet. Just one thing to consider though, the DS Lite can only use WEP encryption.
