LABEL DESCRIPTION

Wireless Advanced Setup

RTS/CTS

Threshold

Enter a value between 0 and 2432. If you select the Enable 802.11g+ mode

checkbox, this field is grayed out and the ZyXEL Device uses 4096 automatically.

Fragmentation

Threshold

It is the maximum data fragment size that can be sent. Enter a value between 256

and 2432. If you select the Enable 802.11g+ mode checkbox, this field is grayed

out and the ZyXEL Device uses 4096 automatically.

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.
