802.1X
802.1X security requires the presence of a RADIUS server, and specifi cation of the IP address of a RADIUS
server, the port on which to connect to it, and the Shared Key used to authenticate with it.
Disregard this security setting unless you are setting up or connecting to a RADIUS server.
WPA
WPA requires a RADIUS server to provide client authentication. WPA also requires specifi cation of the 'WPA
Group Rekey Interval' which is the rate that the RADIUS server sends a new Group Key out to all clients.
The Re-Keying process is part of WPA's enhanced security. This method also requires specifi cation of the IP
address of a RADIUS server, the port on which to connect to the RADIUS server, and the shared key used to
authenticate with the RADIUS server.
WPA-PSK
WPA-PSK is a special mode of WPA providing strong encryption without access to a RADIUS server.
In this mode encryption keys are automatically changed (rekeyed) and authentication re-established between
devices after a specifi ed period referred to as the 'WPA Group Rekey Interval'.
WPA-PSK is far superior to WEP and provides stronger protection for the home/SOHO user for two reasons:
fi rst, the process used to generate the encryption key is very rigorous and second, the rekeying (or key
changing) is done very quickly. This stops even the most determined hacker from gathering enough data to
identify the key and so break the encryption.
WEP is confusing because of the various types of 'network keys' vendors use (HEX, ASCII, or passphrase) and
because home users mix and match equipment from multiple vendors, all using different types of keys. But
WPA-PSK employs a consistent, easy to use method to secure your network. This method uses a passphrase
(also called a shared secret) that must be entered in both the NB9W and the wireless clients. This shared
