BLW-04EX
If you use encryption, configure the same keys used for the BLW-04EX on
each of your wirel ess cli ent s. Not e t hat the Wi red Equi valent Privacy
(WEP) prot ects d at a t ransm itt ed bet ween wireless nodes, b ut does not
protect any transmissions over your wired network or over the Internet.
Encryption
If you are transmitting sensitive data across wireless channels, you should
enable Wired Equivalent Privacy (WEP) encryption.
Encryption requires you to use the same set of encryption/decryption keys
for the BLW-04EX and all of your wireless clients. You can choose between
standard 64-bit or the more robust 128-bit encryption keys.
You can automatically generate encryption keys or you can manually enter
the keys. For automatic 64-bit security, you enter a passphrase that is used
to creat e fou r k eys (as s hown below). The auto matic 128 -b it s ecurit y
generates a single key by entering a passphrase.
