Wi-Fi encryption uses the same key code on the access point and on each client computer to provide access to encrypted data. To add a key code to a Wi-Fi connection profile in Windows, follow these steps:

1. From the Control Panel or the system tray, open the Wireless Network Connection Properties window and choose the Wireless Networks tab.

2. Find the name of the network in the list of Preferred networks and click the Properties button.

3. Open the drop-down Data encryption menu and choose WEP or WPA. If the program offers you a choice of key lengths, choose the longest possible number of digits.

4. Type the same network key that you used to set up encryption on your access point in both network key fields.

5. Click the OK buttons in both open Properties windows to save your settings and close the windows.
