B.1. Lab B.1: Change to WPA Security in Windows XP
This lab requires a Windows XP workstation with a wireless connection.
To change the wireless connection to Wi-Fi Protected Access (WPA) from any other security setting, follow these steps:
Right-click the wireless connection icon in the notification area at the right of the Taskbar.
Choose View Available Wireless Networks.
On the left side of the dialog box, click Change Order of Preferred Networks.
Select the Wireless Networks tab and click on the network you want to change beneath the Preferred Networks section. When it is highlighted, click Properties.
On the Association tab (shown in Figure B.1), choose either WPA or WPA-PSK (the latter incorporates Pre Shared Key and is recommended if you don't have a central authentication server) for Network Authentication.
Figure B.1. The Association tab allows you to configure encryption.
From the Data Encryption drop-down menu, choose either TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) and enter the network key (your wireless password). Confirm the network key by reentering it in the next box.
Click OK to exit this dialog box and OK to exit the earlier dialog boxes.
