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 the NETWORK and WIRELESS 
CARD to display the Wireless Card screen. Select Static WEP from the Security list.

Fragmentation 

Threshold

This is the threshold (number of bytes) for the fragmentation boundary for directed

Select the check box to change the default value and enter a value between 256 and 

2432.
