Have you carried out Network reset on the mini box @Quita43 

Network Reset found in mini Home - Settings - Setup - Network.
Highlight Status and then select Reset on the right hand side. Follow instructions to WPS with main Q box.
You will be asked to press the WPS button on the main Q box (not the mini as the Network reset will start the mini WPS automatically).

If you are on Sky Broadband and the Router is nearer to the mini than the main box then you can try pressing WPS on the router instead of the main Q box
