5 Configuring Access Point Settings Table 13. Static WEP Field WEP Key Length Tx WEP Keys 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 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. 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-tostation 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 802.11i standards, which include AES-CCMP and TKIP mechanisms. The WPA/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. Configuring SSID Settings 103
