5.
If the decrypted text does not match the original challenge text (i.e., the access point and station do
not share the same WEP Key), then the access point will refuse to authenticate the station and the
station will be unable to communicate with either the 802.11b network or Ethernet network.
This process is illustrated in below.

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.
