Can't find AOSS Button in psp

Problem:

It asks me to press and hold the Aoss Button but I'm not sure were it is.

Solution:

1. AOSS (AirStation One-Touch Secure System) is a system by Buffalo Technology which allows a secure wireless connection to be set up with the push of a button. Recent AirStation residential gateways incorporate a button on the unit to let the user initiate this procedure. I think you have to purchase a Buffalo AirStation Router in order to connect your psp. Google "aoss psp". Hope this helped.
