following information carefully.
The wireless security page allows user to configure the security features of user’s
wireless network.
There are several security methods to choose f
rom, depending on user’s needs and the
capabilities of user’s wireless machines.
WEP open
and
WEP shared
—WEP is an encryption scheme that is used to
protect user’s wireless data communications. WEP uses a combination of
64-bit keys or 128-bit keys to pr
ovide 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 not as hard
to break as the more-recent WPA.
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.
Because it requires a separate machine acting as the authentication server,
802.1x is most often used in business environments.
WPA
— WPA is a more recent encryption method that addresses many of the
weaknesses in WEP. Any client capable of WPA encryption should use it
