The wizard will walk you through creating a network name and a security key. If your router will support it, the wizard will default to Wi-Fi Protected Access (WPA) security. We recommend that you use WPA because it offers better security than the traditional Wired Equivalent Privacy (WEP) security. With WPA you can also use a passphrase, so you don’t have to remember a cryptic sequence of letters and numbers.

Make sure that you write down the security key and keep it in a safe place. If you have one, you can also save your security key on a USB flash drive by following the instructions in the wizard.

3.
Enter the security key. You can either type in the key or insert a USB flash drive that contains the security key into a USB port on the computer.
