Overview of WEP Parameters

Before enabling WEP on an 802.11b network, you must first consider what type of encryption you
require and the key size you want to use. Typically, there are three WEP Encryption options
available for 802.11b products:
1. Do Not Use WEP: The 802.11b network does not encrypt data. For authentication purposes, the
network uses Open System Authentication.
2. Use WEP for Encryption: A transmitting 802.11b device encrypts the data portion of every
packet it sends using a configured WEP Key. The receiving 802.11b device decrypts the data using
the same WEP Key. For authentication purposes, the 802.11b network uses Open System
Authentication.
3. Use WEP for Authentication and Encryption: A transmitting 802.11b device encrypts the
data portion of every packet it sends using a configured WEP Key. The receiving 802.11b device
decrypts the data using the same WEP Key. For authentication purposes, the 802.11b network uses
Shared Key Authentication.
Note: Some 802.11b access points also support Use WEP for Authentication Only (Shared Key
Authentication without data encryption). The FVM318 does not support this option.
