appendix.

6.9.1 Wireless Network Overview

Wireless networks consist of wireless clients, access points and bridges.

DESCRIPTION
Delivery Traffic Indication Message (DTIM) is the time period after which
broadcast and multicast packets are transmitted to mobile clients in the
Power Saving mode. A high DTIM value can cause clients to lose
connectivity with the network. This value can be set from 1 to 100.
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 802.11n Only to allow only IEEE 802.11n compliant WLAN
devices to associate with the ZyXEL Device.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g
compliant WLAN devices to associate with the ZyXEL Device. The
transmission rate of your ZyXEL Device might be reduced.
Select 802.11b/g/n Mixed to allow IEEE 802.11b, IEEE 802.11g or
IEEE802.11n compliant WLAN devices to associate with the ZyXEL
Device. The transmission rate of your ZyXEL Device might be reduced.
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 802.11 protection. The transmission rate of your
ZyXEL Device might be reduced in a mixed-mode network.
This field displays Off and is not configurable when you set 802.11
Mode to 802.11b Only.
Select a preamble type from the drop-down list box. Choices are Long or
Short. See the Section 6.9.9 on page 111
This field is configurable only when you set 802.11 Mode to 802.11b.
