Section 3 - Configuration
WPA (Wi-Fi Protected Access)
Wi-Fi Protected Access was designed to provide improved data
encryption, perceived as weak in WEP, and to provide user
authentication, largely nonexistent in WEP.
To take full advantage of WPA, a RADIUS server is needed in your
network to authenticate users. For most home or SOHO users,
WPA-PSK is the easiest way to implement and provides adequate
protection for your wireless network.
Select your wireless security method from the Network Authentication drop-down list.
Enter the RADIUS Server IP Address, Port, and Key.
Select the encryption method from WPA Encryption drop-down list.
Click Save Settings to apply your settings.
