Fragmentation

Select the card slot where the IEEE 802.11b/g card is connected.

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

Select g Only to allow only IEEE 802.11g compliant WLAN devices to associate with

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

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.
