LABEL DESCRIPTION
Wireless Advanced Setup
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.
Output Power Set the output power of the ZyXEL Device in this field. This control changes the
strength of the ZyXEL Device's antenna gain or transmission power. Antenna gain
is the increase in coverage. Higher antenna gain improves the range of the signal
for better communications. If there is a high density of APs within an area, decrease
the output power of the ZyXEL Device to reduce interference with other APs.
The options are
Maximum , Middle and Minimum .
Preamble Select Long preamble if you are unsure what preamble mode the wireless adapters
support, and to provide more reliable communications in busy wireless networks.
Select
Short preamble if you are sure the wireless adapters support it, and to
provide more efficient communications.
Select
Dynamic to have the ZyXEL Device automatically use short preamble when
wireless adapters support it, otherwise the ZyXEL Device uses long preamble.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the ZyXEL Device.
Select
802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the ZyXEL Device.
Select
Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN
devices to associate with the ZyXEL Device. The transmission rate of your ZyXEL
Device might be reduced.
Max. Frame
Burst
Enable Maximum Frame Burst to help eliminate collisions in mixed-mode
networks (networks with both IEEE 802.11g and IEEE 802.11b traffic) and enhance
the performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks.
Maximum Frame Burst sets the maximum time, in micro-seconds, that the
ZZyXEL Device transmits IEEE 802.11g wireless traffic only.
Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800
recommended). Enter 0 to disable this feature.
