Hi, did you find out the cause of the problem as I am experiencing that now, my WiFi router is running as it should as phones and other devices in the house all run fine, I've disconnected both WiFi and tv turned back on still same, in settings on tv I have reset the picture and audio settings and have spoken too sky who took me through trouble shooting and I have too reset the tv in the app, still same problem, they used this new service too sign into my tv and they are saying it's the WiFi connection being unstable although it stayed excellent signal status they have told me I need too order A Ethernet cable too run from the tv too the router, but I've never had any problems with WiFi before
