To configure WPA with pre-shared keys, you need to return to the Wireless Network Properties dialog box, as previously detailed. From the Network Authentication drop-down list, select WPA-PSK. From the Data Encryption drop-down list, select TKIP or AES, as required by your WAP configuration. Enter the pre-shared key, as shown here, and click OK to close the Wireless Network Properties dialog box. Then click OK to close the Wireless Network Connection Properties dialog box. In a few moments, the wireless NIC will authenticate with and connect to the WAP.
Heads Up! You need to obtain the WPA Wireless Security Update for Windows XP (Microsoft Knowledge Base Article 815485) at http://support.microsoft.com/?kbid=815485.
Hardening with WPA Using RADIUS/802.1x
To configure WPA using Radius/ 802.1x, you need to return to the Wireless Network Properties dialog box, as previously detailed. From the Network Authentication drop-down list, select WPA. From the Data Encryption drop-down list, select TKIP, as shown here.
Next, click the Authentication tab to specify the EAP method, as shown next. For the EAP type, select Protected EAP (PEAP). This will cause the wireless client to use WPA and PEAP as the 802.1x authentication method to connect to the WAP. The WAP then encapsulates the user authentication passed using MS-CHAP-v2 into a RADIUS datagram and sends the authentication request to the RADIUS server. The RADIUS server responds with the authentication response, and the WAP either permits the connection, if the user was authenticated, or denies the connection, if the user was not authenticated.
Using the Funk Odyssey Client Version 2.28.0.798 to Support WPA and RADIUS/802.1x
Once you have installed the Odyssey client, select the Odyssey Client Manager from the Start menu. This will cause the Odyssey Client Manager to open, as shown here.
In the column on the left, select Networks and then click Add. Enter the appropriate SSID and select WPA for the association mode and TKIP for the encryption method, as shown at left. In the Authentication section, select the profile to use. When you are finished, click OK.
The next step is to configure the profile you specified in the network’s configuration. Select Profiles and click Properties to edit the initial profile. Select the Authentication tab and click Add to add EAP/PEAP, as shown here. When you are finished, click OK.
The last step is to click Connection and select the network you configured from the drop-down list, as shown here. As soon as you do this, the client will begin authenticating.
When the authentication has successfully completed, your screen should look something like this:
