A gold, unlocked icon next to the connection's name signifies an unlocked WEP (Wired Equivalent Privacy) connection that can be accessed immediately.

You may also click Change Security Settings to enter a WPA (Wi-Fi Protected Access) key.If your WEP key is correct, your Nintendo DSi should connect. You can test your connection to verify.You're set! Now you can surf the Internet, purchase games and add-ons in the Nintendo DSi Shop, and play games that allow wireless access and competition (with WEP connections, only).
