How Do I Configure the Cable Modem Gateway?

 

 

 

Field Name

Description

 

RADIUS Server

Allows you to enter the IP address of the RADIUS

 

 

server used for authentication and encryption key

 

 

derivation.

 

 

ƒ This field is used with 802.1x and WPA Network

 

 

Authentication.

 

 

ƒ The factory default for this field is 0.0.0.0.

 

 

 

 

RADIUS Port

Determines the port number of the RADIUS server.

 

 

The port number is usually 1812 (factory default) or

 

 

1645, depending on the server used.

 

 

This field is used with 802.1x and WPA Network

 

 

Authentication.

 

 

 

 

RADIUS Key

Allows you to set the Shared Secret key for your

 

 

RADIUS connection.

 

 

ƒ The factory default for this field is empty.

 

 

ƒ This field is used with 802.1x and WPA Network

 

 

Authentication.

 

 

 

 

Data Encryption

Allows you to enable data encryption to help secure

 

 

the data that is sent over your wireless network.

 

 

ƒ WEP 128-bit (factory default)

 

 

– 128-bit or-64 bit static key data encryption

 

 

can be selected when the network is

 

 

configured to have no authentication.

 

 

– 128-bit static key data encryption is

 

 

automatically selected when 802.1x network

 

 

authentication is enabled.

 

 

Note: Static key authentication uses one of the

 

 

four encryption keys, as define below, to encrypt

 

 

your data. You must manually change keys. The

 

 

keys do not change or rotate automatically as

 

 

they do with TKIP.

 

 

ƒ TKIP (Temporal Key Integrity Protocol) data

 

 

encryption is automatically enabled when WPA

 

 

and WPA-PSK network authentication is

 

 

enabled.

 

 

Notes:

 

 

ƒ 64-bit and 40-bit encryption are two different

 

 

names for the same encryption

 

 

ƒ 128-bit and 104-bit encryption are two different

 

 

names for the same encryption
