Buffering all the time even with fibre and an ethernet cable direct from the router to the TV box. I have a box in my bedroom but I have not been able to use this as the wifi from the router is not strong enough to reach about 20 foot into my bedroom which is on the same floor. Can't even watch films in 720p as the box is utterly useless and not fit for purpose. Seeing the reviews from others regarding cancellation charges I will be taking advice from Ofcom and Citizens Advice before calling.
