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 wireless networking products from
MyEssentials 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 the entire wireless network, your wireless
networking devices will be unable to communicate with one another on
your network and you will not be able to successfully communicate within
your network.
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 combination 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 Router 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' equipment in your network, the easiest thing
to do is to use the hex WEP key from your Router and enter it manually
into the hex WEP key table in your Router's configuration screen.
