128-bit WEP
As a result of 64-bit WEP’s potential security weaknesses, a more secure
method of 128-bit encryption was developed. 128-bit encryption includes
a key length of 104 bits plus 24 additional bits of system-generated data
(128 bits total). Some hardware manufacturers refer to 128-bit as
104-bit encryption.
Most of the new wireless equipment in the market today supports both 64-bit
and 128-bit WEP encryption, but you might have older equipment that only
supports 64-bit WEP. All Belkin Wireless products will support both 64-bit
and 128-bit WEP.
Encryption Keys
After selecting either the 64-bit or 128-bit WEP encryption mode, it is critical
that you generate an encryption key. If the encryption key is not consistent
throughout all the wireless network your wireless networking devices will be
unable to communicate with one another on your network you will not be
able to successfully communicate within your network. There are two ways to
generate an encryption key - manually
You can enter your key by typing in the HEX Key manually, or you can type in
a Passphrase in the Passphrase field and click “Generate” to create a key. A
HEX (Hexadecimal) key is a mixture of numbers and letters from A–F and 0–9.
For 64-bit WEP you need to enter 10 HEX keys. For 128-bit WEP you need to
enter 26 HEX keys.
For instance:
AF 0F 4B C3 D4 = 64-bit WEP Key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key
The WEP Passphrase is NOT the same as a WEP key. Your Print Server
uses this Passphrase to generate your WEP keys, but different hardware
manufacturers might have different methods on generating the keys. If you
have multiple vendors’ equipments in your network, the easiest thing to do
is to use the HEX WEP key from your Router or Access point and enter it
manually into the HEX WEP key table in your card’s configuration screen.
Most Wi-Fi products ship with security turned off. So once you have your
network working, you need to activate WEP and make sure your wireless
networking devices are sharing the same Network Key. See Figure 1.1.
