802.11b/g Privacy Web Page (Fig. 39)
The Privacy feature in the wireless section encrypts, i.e. effectively “scrambles,” all radio
communication between your gateway and remote wireless-connected PCs. This provides Wired-
Equivalent Privacy (WEP) on your wireless LAN. Use this page to activate encryption if desired,
and set the type to use, as well as the encryption keys.
An easy way to generate encryption keys for WEP is to use the
Generate WEP Keys
button on this
page. First, set Data Encryption to WEP (64) or WEp (129). Then, enter a word or phrase (up to 32
characters long) in the PassPhrase box. Finally, click the
Generate WEP Keys
button. The gateway
will generate digital encryption keys from the phrase and populate the Network Key 1, 2, 3 and 4
boxes with them. You may have to refresh the page in your web browser to see the results.
Advanced users may want to adjust additional security settings. Details of all available settings on
the 802.11b/g Privacy Web Page are provided in Tables 2, 3, and 4.

Setting
Description
Value List or Range
Default
Sets the network authentication method.
802.1X and WPA require that valid RADIUS
parameters be set. WPA-PSK requires a valid
WPA Pre-Shared Key to be set.
Sets the WPA Pre-Shared Key (PSK).
Sets the WPA Group Rekey Interval in
seconds. Set to zero to disable periodic
rekeying.
Sets the IP address of the RADIUS server
to use for authentication and dynamic key
derivation.
Sets the UDP port number of the RADIUS
server. The port number is usually 1812 or
1645 and depends upon the server.
Sets the shared secret for the RADIUS
connection.
Selecting Off disables data encryption.
Selecting WEP enables WEP data
encryption and requires that a valid
network key be set and selected unless
802.1X is enabled.
Sets whether shared key authentication is
required to associate. A valid network key
must be set and selected if required.
Sets the text to use for WEP keys
generation.
Enter 5 ASCII characters or 10
hexadecimal digits for a 64-bit key. Enter
13 ASCII characters or 26 hexadecimal
digits for a 128-bit key.
Selects which network key is used for
encrypting outbound data and/or
authenticating clients.

This page enables some advanced 802.11b settings to be made. The factory default values should
provide good results in most cases. We don’t recommend you change these settings unless you
have technical knowledge of 802.11b wireless technology.
For expert users, details of all settings on the 802.11b/g Privacy Web Page are provided in Table 5.
