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
