Where is the wps button on a N 1 Belkin route?

Using Wi-Fi Protected Setup
WPS uses WPA2 (described below) for encryption. It does not
provide additional security, but rather, standardizes the method for
securing your wireless network. You may use either the Push Button
Configuration (PBC) method or PIN method to allow a device access to your wireless network. Conceptually, the two methods work as follows:
PBC: Push and hold the WPS button located on the back of your
Router for three seconds. Then initiate the WPS procedure on the client device within two minutes. Refer to your client's documentation on this procedure. Pushing the PBC button will automatically enable WPS. The client has now been securely added to your wireless network.
PIN: The client device has a PIN number (either four or eight digits)
that is associated with WPS. Enable WPS through the GUI shown
below. Enter the client's PIN into the Router's internal registrar
(accessed through this GUI). The client will be automatically enrolled
into your wireless network within two minutes.
