64-Bit WEP
64-bit WEP was first introduced with 64-bit encryption, which includes
a key length of 40 bits plus 24 additional bits of system-generated data
(64 bits total). Some hardware manufacturers refer to 64-bit as 40-bit
encryption. Shortly after the technology was introduced, researchers
found that 64-bit encryption was too easy to decode.
128-Bit Encryption
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 WEP 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 WEP and 128-bit
encryption.
Encryption Keys
After selecting either the 64-bit WEP or 128-bit 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.
You can enter your key by typing in the hex key. A hex (hexadecimal)
key is a combination of numbers and letters from A–F and 0–9. For
64-bit WEP, you must enter 10 hex keys. For 128-bit WEP, you must
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
Write down the hex WEP key from your wireless router (or access
point) and enter it manually into the hex WEP key table in your
Adapter's configuration screen.
