Encryption
If you are transmitting sensitive data across wireless channels, you should
enable encryption. You must use the same set of encryption keys for the
Barricade and all of the wireless clients. Choose between standard 64-bit
WEP (Wired Equivalent Privacy) or the more robust 128-bit encryption.
You may automatically generate encryption keys or manually enter the
keys. For automatic 64-bit key generation, enter a passphrase and click
“Generate.” Four keys will be generated. Automatic 128-bit key generation
generates a single key.
