Authentication Type: 
 
The ADSL Router supports two 
authentication types: Open System 
and Shared key. This should be 
considered with the WEP (Wired 
Equivalent Privacy) mechanism. 
Open System means that it allows any 
client to authenticate and attempt to 
communicate with a bridge. The client can 
only communicate if its WEP keys match 
the router’s WEP keys. 
Shared Key means that a bridge or router 
will send an unencrypted text string to any 
client attempting to communicate with the 
router. The client requesting authentication 
encrypts the text and sends back to the 
router. Both unencrypted and encrypted 
can be monitored, yet it leaves the bridge 
open to be attacked by any intruder if he 
calculates the WEP key by comparing the 
text strings. That is why shared key 
authentication can be less secure than 
open authentication. 
 
Format:   
Choose the form of encryption key. 
You have to select either 
Hexadecimal digits or ASCII 
characters
 and type the keys on the 
fields of Key 1 to Key 4. 
Key 1 to 4:   
Fill out the WEP keys according to the 
key length. For 64-bit WEP mode, the 
content you can type is 5 characters 
or 10 hexadecimal digits; for 128-bit 
WEP, the content you can type is 13 
characters or 26 hexadecimal digits.   
Default Transmission Key:   
Select one of the keys that you set on 
the Key boxes as default key. 
Click Apply for activation when the 
settings are done.
