It is to replaced WPA which requires testing and certification by Wi-Fi alliance. WPA2 is to provide a Wi-fi protection for users, a security technology.

All security mechanisms do. It's better to sacrifice couple percents of your bandwidth for secure connection especially if the network is used to access bank accounts, business and so on.
Yes it does,WPA2 is one of the higher encryption setups for wireless. It encrypts the connection between the Router AND the adapters as they talk to each other. They each have to have the sameencryption in order to work.
The two common encryption methods used in wireless networks are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA/WPA2). WEP was the original standard but is now considered insecure. WPA and WPA2 provide stronger encryption and are widely used to secure modern Wi-Fi networks.
The Nintendo DS Internet Connection Interface only allows WEP wireless network. You will have to change a few settings on your router to make this work.
You have to have a router capable of supporting WPA2 as well as a wireless adapter in your computer should support it too. If you are sure that you satisfy both, you need to log in your router, and in settings for wireless network security choose WPA2.
WPA2
Use secure wireless network either WPA or WPA2-PSK. If you prefer to work in open networks (no encryption) you can use VPN connection to protect your activity.
WEP is the most basic and is easily broken by knowledgeable people. WPA2 is newer and is much more seure.
The WPA2 key is a security passphrase used to connect to a Wi-Fi network. It is typically set by the network administrator or the person who set up the Wi-Fi router. The WPA2 key is stored in the router's settings and can usually be accessed by logging into the router's configuration page through a web browser. It is important to keep the WPA2 key secure and not share it with unauthorized users to prevent unauthorized access to the network.
A WPA2 passphrase is a security key used to protect wireless networks that employ the WPA2 (Wi-Fi Protected Access 2) protocol. It is typically a string of characters, including letters, numbers, and symbols, and is required for devices to connect securely to the network. The passphrase should be strong and complex to enhance security and prevent unauthorized access. Users can set or change the passphrase through their router's configuration settings.
WPA2 with AES is more secure than TKIP. As of December 2009, TKIP is considered breakable while AES is currently considered not breakable.
