connecting via WPS (Wi-Fi Protected Setup)

Hello,

I am trying to connect to a router via WPS. At the moment this
requires pushing the pushbutton on the router prior to
connecting. I would like to be able to connect by entering
a PIN into the router or pressing a pushbutton on the laptop
that connects to the router. Alas, my laptop is brand new but
I see no hardware pushbutton (is there a software pushbutton
somewhere)? I cannot even find a PIN on my laptop (I can only
see the router's PIN via HTTP from another laptop).

I don't want to have to push the push button on the router every
time I disconnect from a laptop and reconnect.

How should I proceed?

Suggestions welcome,

Thanks,

John Goche
