2nd sky q mini box

[DM111111]

Hi

i have a sky Q main box  connected via Ethernet and a mini box connected wirelessly with the main box. I want to add a 2nd mini box will it connect to the mini box wirelessly? 
I live in a large bungalow so I know the 2nd mini would not reach the main box 

also my WiFi is not compatible with sky hence the Ethernet connection to main box 

thankd

Yes, all detailed in links below;

Just do it via the wps option on both minis;
