 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.

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.
