ZyXEL Communications P-2602HWLNI User Manual

 Chapter 9 Wireless LAN

P-2602HWLNI User’s Guide

The following table describes wireless network terms and acronyms used in the ZyXEL 
Device’s Web Configurator.

"

If you are configuring the ZyXEL Device from a computer connected to the 
wireless LAN and you change the ZyXEL Device’s SSID or security settings, 
you will lose your wireless connection when you press Apply to confirm. You 
must then change the wireless settings of your computer to match the ZyXEL 
Device’s new settings.

Click Network > Wireless LAN to open the Wireless LAN General screen.

Table 35   Additional Wireless Terms

Intra-BSS Traffic

This describes direct communication (not through the ZyXEL Device) between 

two wireless devices within a wireless network.  You might disable this kind of 

communication to enhance security within your wireless network.

RTS/CTS Threshold

Use RTS/CTS to reduce data collisions on the wireless network if you have 

wireless clients that are associated with the same AP but out of range of one 

another. When enabled, a wireless client sends an RTS (Request To Send) 

and then waits for a CTS (Clear To Send) before it transmits. This stops 

wireless clients from transmitting packets at the same time (and causing data 

collisions).
A wireless client sends an RTS for all packets larger than the number (of 

bytes) that you enter here. Set the RTS/CTS equal to or higher than the 

fragmentation threshold to turn RTS/CTS off.

Preamble

A preamble affects the timing in your wireless network. There are two 

preamble modes: long and short.

 

If a device uses a different preamble mode 

than the ZyXEL Device does, it cannot communicate with the ZyXEL Device.

Authentication

The process of verifying whether a wireless device is allowed to use the 

wireless network.

Max. Frame Burst

Enable this to improve the performance of both pure IEEE 802.11g and mixed 

IEEE 802.11b/g networks. Maximum Frame Burst sets the maximum time that 

the ZyXEL Device  transmits IEEE 802.11g wireless traffic only.

Fragmentation 

Threshold

A small fragmentation threshold is recommended for busy networks, while a 

larger threshold provides faster performance if the network is not very busy.

Roaming

If you have two or more ZyXEL Devices (or other wireless access points) on 

your wireless network, you can enable this option so that wireless devices can 

change locations without having to log in again. This is useful for devices, 

such as notebooks, that move around a lot.
