LABEL	DESCRIPTION
WLAN Device
Settings
Enable WLAN	Select this option to turn on the wireless LAN card. It is recommended that you
Device	configure the wireless security settings before you use this option to turn on a
	wireless LAN card.
802.11 Band	Select whether you will let wireless clients connect to the ZyWALL using IEEE
	802.11b, IEEE 802.11g, or both.
	Select b Only to allow only IEEE 802.11b compliant WLAN devices to associate with
	the ZyWALL.
	Select g Only to allow only IEEE 802.11g compliant WLAN devices to associate with
	the ZyWALL.
	Select b+g to allow both IEEE802.11b and IEEE802.11g compliant WLAN devices to
	associate with the ZyWALL. The transmission rate of your ZyWALL might be
	reduced.
Channel	This allows you to set the operating channel depending on your particular region.
	Select a channel from the drop-down list box.
Super Mode	Select this to improve data throughput on the WLAN by enabling fast frame and
	packet bursting.
CTS/RTS	Use CTS/RTS to reduce data collisions on the wireless network if you have wireless
Threshold	clients that are associated with the same AP but out of range of one another. When
	enabled, a wireless client sends an RTS (Request To Send) and then waits for a
	CTS (Clear To Send) before it transmits. This stops wireless clients from transmitting
	packets at the same time (and causing data collisions).
	A wireless client sends an RTS for all packets larger than the number (of bytes) that
	you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold
	to turn RTS/CTS off.
Fragmentation	This is the threshold (number of bytes) for the fragmentation boundary for directed
Threshold	messages. It is the maximum data fragment size that can be sent.
Output Power	Set the output power of the ZyWALL in this field. If there is a high density of APs in
	the area, decrease the output power of the ZyWALL to reduce interference with other
	APs. Select one of the following 100%, 50%, 25%, 12.5% or Minimum. See the
	product specifications for more information on your ZyWALL’s output power.
#	This field is a sequential value, and it is not associated with any interface.
