Note: If you are configuring the ZyXEL Device from a computer connected to the
wireless LAN and you change the ZyXEL Device's SSID or WEP 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.

Chapter 9 Wireless LAN
DESCRIPTION
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.
In a wireless network which covers a large area, wireless devices are
sometimes not aware of each other's presence. This may cause them to send
information to the AP at the same time and result in information colliding and
not getting through.
By setting this value lower than the default value, the wireless devices must
sometimes get permission to send information to the ZyXEL Device. The lower
the value, the more often the devices must get permission.
If this value is greater than the fragmentation threshold value (see below), then
wireless devices never have to get permission to send information to the
ZyXEL Device.
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.
The process of verifying whether a wireless device is allowed to use the
wireless network.
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.
A small fragmentation threshold is recommended for busy networks, while a
larger threshold provides faster performance if the network is not very busy.
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.
