Rules To Remember For Static WEP
•
All client stations must have the Wireless LAN (WLAN) security set to WEP and all
clients must have one of the WEP keys specified on the AP in order to de-code AP-to-
station data transmissions.
•
The AP must have all keys used by clients for station-to-AP transmit so that it can de-
code the station transmissions.
•
The same key must occupy the same slot on all nodes (AP and clients). For example if
the AP defines
abc123
string as WEP key 3.
The authentication algorithm defines the method used to determine whether a client station is allowed to
associate with an access point when static WEP is the security mode. Specify the authentication algorithm
you want to use by choosing one of the following from the drop-down menu:
• Open System.
• Shared Key.
• Both.
Open System authentication allows any client station to associate with the access point whether that client
station has the correct WEP key or not. This is algorithm is also used in plaintext, IEEE 802.1x, and WPA
modes. When the authentication algorithm is set to "Open System", any client can associate with the
access point.
Note that just because a client station is allowed to associate does not ensure it can exchange traffic with
an access point. A station must have the correct WEP key to be able to successfully access and decrypt
data from an access point, and to transmit readable data to the access point.
Shared Key authentication requires the client station to have the correct WEP key in order to associate
with the access point. When the authentication algorithm is set to "Shared Key", a station with an incorrect
WEP key will not be able to associate with the access point.
Both is the default. When the authentication algorithm is set to "Both":
• Client stations configured to use WEP in shared key mode must have a valid WEP key in order
to associate with the access point.
• Client stations configured to use WEP as an open system (shared key mode not enabled) will
be able to associate with the access point even if they do not have the correct WEP key.
key as WEP key 3, then the client stations must define that same
