    Router configuration

     1. Open a Web Browser
     2. In the address bar type http://192.168.2.1 
     3. Click on Security in the left hand column under Wireless
     4. Enter your password if any and click Submit
     5. Select WPA-PSK (no server) from the Security Mode section
    Note: If you have a RADIUS infrastructure, select WPA (with Radius Server)
     6. Enter your Pre-shared Key
    Note: You can mask your Pre-shared Key by selecting Obscure PSK
     7. Click on Apply Changes

    Network adapter configuration

    1. Click Start, and then click My Network Places
    2. Under Network Tasks, click View Network Connections. (Or, you can right-click My Network Places on the desktop, and then click Properties.)
    3. Right-click the connection that you use for the Internet, and then click Properties
    4. Under Wireless Networks, check Use Windows to configure my wireless networking settings
    5. Select your wireless network under Available networks, click Configure.
    6. Under Association select, Network Authentication and choose the equivalent Security Mode
    7. Under Data encryption choose the equivalent encryption protocol
    8. Enter your network key
    9. Click Ok

    Features of WPA Security
    The following security features are included in the WPA standard:

    WPA Authentication

    For environments without a Remote Authentication Dial-In User Service (RADIUS) infrastructure, WPA supports the use of a preshared key. For environments with a RADIUS infrastructure, Extensible Authentication Protocol (EAP) and RADIUS is supported.

    Temporal Key Integrity Protocol (TKIP)
    For 802.11g, Wired Equivalent Privacy (WEP) encryption is now optional. For WPA, encryption using TKIP is required. TKIP replaces WEP with a new encryption algorithm that is stronger than the WEP algorithm but that uses the calculation facilities present on existing wireless devices to perform encryption operations. TKIP also provides for the following:

    ·  The verification of the security configuration after the encryption keys are determined.
    ·  The synchronized changing of the unicast encryption key for each frame.
    ·  The determination of a unique starting unicast encryption key for each preshared key authentication.

    AES Support

    WPA defines the use of Advanced Encryption Standard (AES) as an additional replacement for WEP encryption. Because you may not be able to add AES support through a firmware update to existing wireless equipment, support for AES is optional and is dependant on vendor driver support.
