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).
