AirPort Utility supports two WPA2 modes: Enterprise mode, which uses a RADIUS server for user authentication, and Personal mode, which doesn’t require a RADIUS server.
Enterprise mode is designed for a larger network that an IT professional is most likely setting up and managing. In order to set up a WPA Enterprise network, an 802.1X connection must be set up first. The 802.1X connection requires an authentication protocol, such as TTLS, LEAP, or PEAP. It also requires an authentication server to manage network users’ credentials and certificates.

Personal mode is for the home or small office network and can be set up and managed by most users. Personal mode does not require a separate authentication server. Users of the network usually need only enter a user name and password to join the network.
Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X, and in Start > All Programs > AirPort on a Windows computer.
Select the device you’re setting up, and then click Manual Setup. Enter the password if necessary.
Click AirPort in the toolbar, and then click Wireless.
Choose WPA/WPA2 Personal from the Wireless Security pop-up menu if you want computers compatible with WPA and WPA2 to join your network. Choose WPA2 Personal if you want only computers compatible with WPA2 to join your network.
