128-Bit WEP

As a result of 64-bit WEP’s potential security weaknesses, 128Bit
WEP was developed as a more secure method of encryption. 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 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 mixture of numbers and
letters from A–F and 0–9. For 64-bit WEP, you need to enter 10 hex
characters. For 128-bit WEP, you need to enter 26 hex characters.

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 wireless
card uses this passphrase to generate your WEP keys, but different
hardware manufacturers might have different methods for generating
the keys. If you have equipment from multiple vendors in your
network, you can use the hex WEP key from your Router or access
point and enter it manually into the hex WEP key table in your
wireless card’s configuration screen.
