Configuring Security
Key Management
Static WEP uses a fixed key that
is provided by the administrator.
WEP keys are indexed in different
slots (up to four on the D-Link
DWL -2210AP).
The client stations must have the
same key indexed in the same
slot to access data on the access
point.
Recommendations
Static WEP was designed to provide the security equivalent of sending unencrypted
data through an Ethernet connection, however it has major flaws and it does not provide
even this intended level of security.
Therefore, Static WEP is not recommended as a secure mode. The only time to use Static
WEP is when interoperability issues make it the only option available to you and you
are not concerned with the potential of exposing the data on your network.

For information on how to configure Static WEP security mode, see "Static WEP"
under "Configuring Security Settings" in this manual.
When to Use IEEE 802.1x
IEEE 802.1x is the standard for passing the Extensible Authentication Protocol (EAP)
over an 802.11 wireless network using a protocol called EAP Encapsulation Over
LANs (EAPOL). This is a newer, more secure standard than static WEP.
Encryption Algorithm
An RC4 stream cipher
is used to encrypt the
frame body and cyclic
redundancy checking
(CRC) of each 802.11
frame.

User Authentication
If you set the Authentication
Algorithm to Shared Key, this
protocol provides a rudimentary
form of user authentication.
However, if the Authentication
Algorithm is set to "Open
System", no authentication is
performed.
If the algorithm is set to
"Both", only WEP clients are
authenticated.
