Static WEP Rules
If you use Static WEP, the following rules apply:
• 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
as WEP key 3.
• 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.)
• On some wireless client software, you can configure multiple WEP keys and define a
client station "transfer key index", and then set the stations to encrypt the data they
transmit using different keys. This ensures that neighboring APs cannot decode each
other's transmissions.
• You cannot mix 64-bit, 128-bit, and 152-bit WEP keys between the access point and its
client stations.
Example of Using Static WEP
In this example, the administrator configures three WEP keys on the access point and sets the
Transfer Key Index to "3." This means that the WEP key in slot "3" is the key the access point
uses to encrypt the data it sends.

The administrator must then set all wireless client stations to use WEP and provide each client
with one of the slot/key combinations defined on the AP.

cause the AP to stop and restart system processes. If this happens, wireless
clients will temporarily lose connectivity. We recommend that you change
access point settings when WLAN traffic is low.
key as WEP key 3, then the client stations must define that same string
