as 64 bit Wired Equivalent Privacy or WEP for short. The default 64 bit Hexadecimal WEP key is:
a1b2c3d4e5
Select the WEP mode for the security function; there are two options, 64-bit and 128-bit. Before being
transmitted, the data will be encrypted using the encryption key. For example, if you set 64-bit in this
field, then the receiving station must be set to use 64 Bit Encryption, and have the same Key value at
the same time; otherwise, it will not be able to decrypt the data.
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.
For 802.1X Wireless Network
When a wireless client requests to access a network, it is required to be authenticated by a central
authentication server (RADIUS Server). Only an authenticated user can be granted by the network
access and thereby those unauthorized will be blocked.
