The WPS button can be labelled in various ways and depending on the device, the location of the button can vary as well.  The button on some devices may be directly on the front.  Others may be located on the back.  The button itself may be labelled simply as "WPS" or "Wi-Fi Protected Setup".  There may also be some symbols associated with the WPS button (see below).

 If you are unable to locate this button, please refer to the documentation that came with your wireless router for information.
