To set up WPA or WPA2 wireless security:

1.In the Security Options section of the Wireless Settings screen, leave the default setting or select one of the WPA settings:

•WPA-PSK. This setting provides the TKIP encryption type and a pre-shared key passphrase.

•WPA2-PSK. This setting provides the AES encryption type and a pre-shared key passphrase.

2.Depending on the WPA settings that you select, enter the required information.

For WPA-PSK or WPA2-PSK, enter the

pre-shared key, which is a passphrase between 8 and 63 characters. The default WPA passphrase is the 13-character serial number of your gateway.

3.Click Apply to save your settings.

Note: If you plan to use WPS, and you want to keep your wireless settings the same, go to the Advance Wireless Settings screen and make sure that the Keep Existing Settings checkbox is selected. See

“Advanced Wireless Settings” on page 17.

4.Configure your wireless computers with the same WPA2 or WPA settings as your gateway so that you will be able to connect.

WEP Security

Note: By default, the gateway is set up to work with WPA and WPA2 wireless security, both of which are newer than WEP. Typically, the only reason you might need to set up WEP would be to allow access to older wireless computers or devices that cannot support WPA.
