WEP
WEP is a common protocol that adds security to all Wi-Fi-compliant wireless products. WEP
gives wireless networks the equivalent level of privacy protection as a comparable wired
network.
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. You can enter your key by typing in the hex key manually, or
you can type a passphrase into 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 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 card 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 wireless router and enter it
manually into the hex WEP key table in your card' s configuration screen.
