Enabling the RTS Threshold causes redundant network overhead that could
negatively affect the throughput performance instead of providing a remedy.
6.1.5 Fragmentation Threshold
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.

Levels of Security

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. The highest security level
relies on EAP (Extensible Authentication Protocol) for authentication and utilizes dynamic Wired Equivalent
Privacy (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 the
chapter on using the Prestige web configurator to see how to access the web configurator.
