WEP Encryption and Authentication

Wired Equivalent Privacy (WEP) encryption and shared authentication provides protect
for your data on the network. WEP uses an encryption key to encrypt data before
transmitting it. Only computers using the same encryption key can access the network or
decrypt the encrypted data transmitted by other computers. Authentication provides an
additional validation process from the adapter to the access point.

Supported a uthentication schemes are Open and Shared-Key authentication:

●

Shared-Key authentication is supported using 64-bit and 128-bit WEP encryption
keys.

●

Open mode does not use an encryption authentication method to associate to a
specific access point.

Network Keys

When Data Encryption (WEP, CKIP or TKIP) is enabled, a network key is used for
