7.4.2 WEP Encryption
WEP encryption scrambles the data transmitted between the wireless clients and the access
points to keep network communications private. It encrypts unicast and multicast
communications in a network. Both the wireless clients and the access points must use the
same WEP key.
Your ZyXEL device allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys
but only one key can be enabled at any one time.
In order to configure and enable WEP encryption; click Network > Wireless LAN to display
the General screen. Select Static WEP from the Security Mode list.
Figure 58 Wireless: Static WEP Encryption
The following table describes the wireless LAN security labels in this screen.
Table 34 Wireless: Static WEP Encryption
LABEL DESCRIPTION
Security Mode Choose Static WEP from the drop-down list box.
Passphrase Enter a Passphrase (up to 32 printable characters) and clicking Generate. The ZyXEL
device automatically generates a WEP key.
