For example if the AP definesabc12key 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 samekey, 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. Thisensures 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 EnterpriseWPA and WPA2 are Wi-Fi Alliance IEEE 802.11i standards, which include AES-CCMP and TKIP mechanisms. TheWPA/WPA2 Personal employs a pre-shared key to perform an initial check of credentials. The WPA/WPA2Enterprise security uses a RADIUS server to authenticate users.WEP Key LengthSpecify the length of the key by clicking one of the radio buttons:•64 bits•128 bitsTxThe Transfer Key Index indicates which WEP key the access point uses to encrypt thedata it transmits. To select a transfer key, click the button located between the keynumber and the field where you enter the key. In Figure 363, the transfer keyis 3.WEP KeysYou can specify up to four WEP keys. In each text box, enter a string of characters foreach key. These are the RC4 WEP keys shared with the stations using the accesspoint.Use the same number of characters for each key. The number of keys you enterdepends on the Key Type and Key Length. The following list shows the number ofkeys to enter in the field:•64 bit: ASCII: 5 characters; Hex: 10 characters•128 bit: ASCII: 13 characters; Hex: 26 charactersEach client station must be configured to use one of these same WEP keys in thesame slot as specified here on the AP.Note:The 802.11n clients cannot use the TKIP cipher. Therefore if only TKIP is enabled then the802.11 clients will not be able to authenticate with the network.Table 331: Static WEP (Cont.)FieldDescription
