I just upgraded my old Sony TV for a LG 55NANO796. The WiFi and wired ethernet speeds are not adequate to support 4K streaming over Internet. I installed a FTTH 900meg service with intention of streaming 4KHD TV, stream is pausing every minute or so for 3-5s while download catches up. TV is very close to a WiFi mesh AP with RJ45 socket, WiFi and cable speeds on TV webOS are similar, ping of 40ms, 16Meg down and 95M upload. I'm measuring speed with Speedtest.net. I connected Raspberry Pi4 media Centre (£35) and got 7ms & 110M up and down from same AP connection. LG have clearly underspeced the Ethernet buffer for 4K streaming.
