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 mode, the content you can type 
is 13 characters or 26 hexadecimal 
digits.  
Default Transmission Key:   
Select one of the network keys that 
you set on the Key boxes as the 
default one. 
Click Apply for activation when the 
settings are done.
