A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 
bytes) that can be sent in the wireless network before the Prestige will fragment the packet into 
smaller data frames.

A large Fragmentation Threshold is recommended for networks not prone to interference 
while you should set a smaller threshold for busy networks or networks that are prone to 
interference.

If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) 
you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as 
data frames will be fragmented before they reach RTS/CTS size.

Wireless security is vital to your network to protect wireless communication between wireless 
stations, access points and the wired network.

The figure below shows the possible wireless security levels on your Prestige. EAP 
(Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key 
exchange. It requires interaction with a RADIUS (Remote Authentication Dial-In User 
Service) server either on the WAN or your LAN to provide authentication service for wireless 
stations.

If you do not enable any wireless security on your Prestige, your network is accessible to any 
wireless networking device that is within range. 

Use the Prestige web configurator to configurator to set up your wireless LAN security 
settings. Refer to 

 to see how to access the web configurator.
