Hi, I have been having a same type of problem with the ethernet conection, my picture just frezze's after about 15mins, if I conect just through the wifi it last about an hour before frezzing, when it frezzes if I go up a channel and then go back it un frezzes, (Air Tv) , my broadband provider is Sky, I have the Sky Fibre max running at around 80mb/s.

Any help would be good, tried all sorts of various settings.

Thanks
