Wireless-N ADSL2+ Gateway

RADIUS

This option features WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Gateway.)

• RADIUS Server. Enter the IP address of the RADIUS server.

• RADIUS Port. Enter the port number of the RADIUS server.

 

• Shared Key. Enter the key shared between the Gateway and its RADIUS server.

 

• Encryption. Select the appropriate level of encryption, 40/64-bit (10 hex digits) or 104/128-bit (26 hex

 

digits). A higher level of encryption is more secure.

 

• Passphrase. Instead of manually entering WEP keys, you can enter a Passphrase. It is case-sensitive and

 

should not be longer than 32 alphanumeric characters. (This Passphrase function is compatible with Linksys

 

wireless products only and cannot be used with Windows XP Zero Configuration. If you want to communicate

Figure 5-18: Wireless Security - RADIUS

with non-Linksys wireless products or Windows XP Zero Configuration, make a note of the WEP keys

 

generated, and enter the appropriate one manually in the wireless computer or client.) If you want to use a

 

Passphrase, then enter it in the Passphrase field and click the Generate button.

 

• Keys 1-4. If you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field

 

blank, and do not enter all zeroes; they are not valid key values.) If you are using 40/64-bit WEP encryption,

 

the key must be exactly 10 hexadecimal characters in length. If you are using 104/128-bit WEP encryption,

 

the key must be exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and

 

“A”-“F”.

 

• TX Key. To indicate which WEP key to use, select a default Transmit (TX) Key number.
