of 64-bit keys or 128-
bit keys to provide access control to user’s network
and encryption security for every data transmission. To decode a data
transmission, each wireless client on the network must use an identical
64-bit or 128-bit key. WEP is an older wireless encryption method that is

802.1x
— In 802.1x (also known as RADIUS), a separate machine called an
authentication server receives a user ID and password. It grants or denies
access based on whether the ID and password match any entries in its
account list. User can optionally enable WEP encryption with this option.
