Enable WLAN

Select this 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.

 

Select b+g+n to allow IEEE802.11b, IEEE802.11g and IEEE802.11n

 

compliant WLAN devices to associate with the ZyWALL. The transmission

 

rate of your ZyWALL might be reduced.

 

Select g+n to allow both IEEE802.11g and IEEE802.11n 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.

 

 

CTS/RTS

Use CTS/RTS to reduce data collisions on the wireless network if you

Threshold

have wireless 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

Threshold

for directed messages. It is the maximum data fragment size that can be

 

sent.

 

 

Output Power

Select the percentage of output power that this WLAN card is to use. If

 

there is a high density of APs in the area, decrease the output power of

 

the ZyWALL to reduce interference with other APs. See the product

 

specifications for more information on your ZyWALL’s output power.
