This section discusses wireless LANs in depth. For more information, see the
appendix.

54g

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 802.11g 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

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.

This field displays Off and is not configurable when you set 54g

Mode

to 802.11b Only.

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.

This field displays Short and is not configurable when you set 54g

Mode to 54g Performance.
