Push 'N' Connect (WPS) Wireless Setup

Push 'N' Connect (WPS) can be a quick way to automatically set up your gateway’s wireless network and set up your wireless computer to connect to it at the same time. WPS, also called Wi-Fi Protected Setup, is relatively new technology, so before you decide to use it, check to make sure your wireless computers and devices support WPS. Look for the

symbol on all the computers that will connect wirelessly to the gateway.

If you do not see the symbol on all the computers that will connect to the wireless network, then you should manually set up your network first (see Manually Configure The

Wireless Settings ). After that, you can still use WPS to set up the wireless connection for the

computers that support WPS.

Note: All WPS-capable products should be compatible with the gateway.

For more detailed information about the WPS standard, see

http://www.wi-fi.org).

There are two Push 'N' Connect methods, Push Button and PIN (personal identification number).

• Push Button. This is the preferred method. See the following section, WPS Button .

• PIN. See PIN on page 17.

WPS Button

You can use the WPS button to automatically set up wireless settings in your gateway and to set up your wireless computer to connect to it.

1. First, make sure you know how WPS works on your computer or wireless device. If it

works with WPS, it has a WPS utility and might also have a WPS button that you can press.

2. Select Add WPS Client and then click Next. The Add WPS Client screen displays:

Any computer or wireless device that will wirelessly connect to the gateway is a client. After it is added as a client, it will be able to automatically connect to the gateway.
