Chapter 13: Configuring Security
Static WEP
WEP encrypts data moving across the wireless network based on a static key.
(The encryption algorithm is a “stream” cipher called RC4.) The access point uses a
key to transmit data to the client stations. Each client station must use that same key
to decrypt data it receives from the access point.
Client stations can use different keys to transmit data to the access point. (Or they
can all use the same key, but this is less secure because it means one station can
decrypt the data being sent by another.)
If you selected “Static WEP” Security Mode, provide the following on the access
point settings:
Field Description

it transmits.
