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 abc12 key as
WEP key 3, then the client stations must define that same string 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.
Using WPA/WPA2 Personal or Enterprise
WPA and WPA2 are Wi-Fi Alliance IEEE
WPA2 Personal employs a pre-shared key to perform an initial check of credentials. The WAP/WPA2 Enterprise uses a
RADIUS server to authenticate users.

Table 16: Static WEP
Description
Specify the length of the key by clicking one of the radio buttons:
• 64 bits
• 128 bits
• 152 bits
The Transfer Key Index indicates which WEP key the access point uses to encrypt the data it
transmits. To select a transfer key, click the button located between the key number and the
field where you enter the key. In <Link>Figure 45, the transfer key is 3.
You can specify up to four WEP keys. In each text box, enter a string of characters for each
key. These are the RC4 WEP keys shared with the stations using the access point.
Use the same number of characters for each key. The number of keys you enter depends on
the Key Type and Key Length. The following list shows the number of keys to enter in the field:
• 64 bit—ASCII: 5 characters; Hex: 10 characters
• 128 bit—ASCII: 13 characters; Hex: 26 characters
• 152 bit—ASCII: 16 characters; Hex: 32 characters
Each client station must be configured to use one of these same WEP keys in the same slot
as specified here on the AP.
