10.16.1 Static WEP
Static WEP provides a mechanism for encrypting data using encryption keys. Both the AP and
the wireless stations must use the same WEP key to encrypt and decrypt data. Your ZyWALL
allows you to configure up to four 64-bit or 128-bit WEP keys, but only one key can be used at
any one time.
In order to configure and enable WEP encryption, click WIRELESS > Wi-Fi > Wireless
Card to display the Wireless Card screen. Select Static WEP from the Security list.
RTS/CTS
Threshold
Use RTS/CTS 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.
Fragmentatio
n Threshold
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.
