How is the puck connected to the Internet ? If you can connect it with an ethernet cable more stable, also what is your broadband speed to the puck, you can find this out by opening Netflix going to help opening that and running check my network to see what speed your are getting, also the more devices that you have connected to the Internet the weaker the signal is to each one, sky say to watch hd channels you need a minimum broadband speed of 25mps and to watch uhd channels you need a minimum of 35mps, I am on sky gigafast broadband 900mps i have 2 55inch sky glass tvs and a puck, sky live camera and a very busy household games consoles laptops tablet, freesat box, smart meter, 3 mobile phones alexers and no problems at all
