The following figure provides an example of a wireless network.
Table 26 Wireless LAN > Advanced Setup
LABEL DESCRIPTION
RTS/CTS
Threshold Enter a value between 0 and 2432.
Fragmentation
Threshold This is the maximum data fragment size that can be sent. Enter a value between 256
and 2432.
Number of
Wireless
Stations
Allowed Specify the maximum number of the wireless stations that may connect to the ZyXEL
Device.
Output Power Set the output power of the ZyXEL Device. If there is a high density of APs in an area,
decrease the output power to reduce interference with other APs. Select one of the
following
20% , 40% , 60% , 80% or 100% .
54g
TM
Mode Select 54g Auto to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN
devices to associate with the ZyXEL Device. The ZyXEL Device adjusts the
transmission rate automatically according to the wireless standard supported by the
wireless devices.
Select
54g Performance to allow only IEEE 802.11b compliant WLAN devices to
associate with the ZyXEL Device.
Select
802.11b Only to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN
devices to associate with the ZyXEL Device. In this mode, all wireless devices can
only transmit at the data rates supported by IEEE 802.11b.
54g
TM
Protection
Enabling this feature can help prevent collisions in mixed-mode networks (networks
with both IEEE 802.11b and IEEE 802.11g traffic).
Select
Auto to have the wireless devices transmit data after a RTS/CTS handshake.
This helps improve IEEE 802.11g performance.
Select
Off to disable 54g protection. The transmission rate of your ZyXEL Device
might be reduced in a mixed-mode network.
Preamble Select a preamble type from the drop-down list menu. Choices are Long or Short .
The default setting is Long . See the appendix for more information.
