I am wondering why you would need to turn off the wireless. The DS wireless is not like having wireless computer access. The wireless technology is to play multi player games with a friend and cannot be accessed by a random person. First, the person using the DS must have a game that can be played by multi players. Second, they must give out their password to the second player in order to be invited into playing a game, hence, they must know the other player to be able to physically talk to them in person or on the phone. There is no personal information exchanged. The only other "wireless" activity you can do with the Ds is a little "chat" program but you must be within a very, very short distance, like in the same house. They cannot surf the web or go on the internet with this system. It is a very simple wireless system, unlike the PSP where you have true wireless internet access.
