Shared: Requires that the station and the access point use the same WEP key to authenticate. This basically means that WEP must be enabled and configured on both the access point and the client with a same key.
 -26- WPA-PSK: Allows you to gain access to a secured wireless network that the station and the access point use the same pre-shared key to authenticate. You must type an alphanumeric password phrases between 8 and 63 characters in the  Pre-shared key [WPA] section of this menu. Pre-shared key is usually used for SOHO authentication.  WPA:  Allows you to gain access to a more secured wireless network that requires mutual authentication between client and access point with a Radius authentication server. This product supports two EAP types (TLS and PEAP), which require different credential authentication. In order to access the wireless network, you must select EAP type your service provider supplied in the section of IEEE802.11X Authentication.   WPA consists of methods to strengthen data encryption (Wired Equivalent Privacy [WEA], Temporal key integrity Protocol [TKIP], Advanced Encryption Standard [AES]) and to provide user authentication (strong EAP type such as TLS, PEAP, LEAP). There are two authentication mechanisms, one for small business and home wireless LAN users using a shared secret key without 802.1X (so called WPA-Pre-Shared Key), and another for  “Enterprise” users using 802.1X or RADIUS (so called WPA-EAP).   Once you choose your Authentication Mode, you then need to select the Encryption Mode.  WEP: Specify the encryption keys. There are two methods to set the WEP keys, as described below: Key will be generated automatically for data private To create encryption keys automatically, click the Key will be generated automatically for data private check box.  Note: This function is used in IEEE802.1X Authentication mode. Keys are dynamically generated and distributed by the authentication server. Actually, you can obtain keys by asking your service provider for further configuration and information to gain access to the wireless network.
 -27- Pre-configured key [WEP] You can also create encryption keys manually by pulling down the Key Length menu and select either 64bit or 128bit encryption method in the Pre-configured key section of this menu. For 64bit encryption you may choose: n Alphanumeric: entering 5 characters (case sensitive) ranging from  “a-z”,  “A-Z” and “0-9” (e.g. MyKey) n Hexadecimal: entering  10 hexadecimal digits  in the range of “A-F”,  “a-f”  and “0-9” (e.g. 11AA22BB33) For 128bit encryption you may choose: n Alphanumeric: entering 13 characters (case sensitive) ranging from  “a-z”, “A-Z” and “0-9” (e.g. MyKey12345678) n Hexadecimal:  entering 26 hexadecimal digits  in the range of “A-F”,  “a-f”  and “0-9” (e.g. 00112233445566778899AABBCC). After you type, the utility uses an algorithm to generate 4 keys automatically. The Key index field allows you specify which of the four keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the up or down arrow and make sure the default key is set up exactly the same on the Wireless LAN stations as they are on the wireless Access Points. After entering the WEP keys in the key field, click the  OK button to make the setting take effect.   TKIP: A greatly enhanced wireless encryption scheme. Designed to enhance protection by most popular WPA-capable devices. When TKIP is enabled, the key value will be generated automatically for data private. AES: A sophisticated wireless encryption scheme. Designed to increase the strength and complexity of wireless encryption. When AES is enabled, the key value will be generated automatically for data private. If the Security you are configuring requires authentication, simply click the check box next to Enable IEEE802.1X authentication for this network  in the  IEEE802.1X Authentication section of this menu, and you can choose an EAP type.
