DESCRIPTION
Select this option to turn on the wireless LAN card. It is recommended that you
configure the wireless security settings before you use this option to turn on a
wireless LAN card.
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.
This allows you to set the operating channel depending on your particular region.
Select a channel from the drop-down list box.
Select this to improve data throughput on the WLAN by enabling fast frame and
packet bursting.
Use CTS/RTS to reduce data collisions on the wireless network if you 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.
This is the threshold (number of bytes) for the fragmentation boundary for directed
messages. It is the maximum data fragment size that can be sent.
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.
