Usually caused by handmade Ethernet cables. But here's the rub. Netflix even at HD needs less than 10megabit.
I have recently bought a Samsung Smart TV model UE65JU7000. And I have found that its Ethernet wired connection is very slow and only gets up to 10 MBps download speed and about 20 Mbps upload. At home I have a 200/200 mbps fiber connection, so it should clearly perform better than that. And in fact when I connect the TV through wireless I can get it up to 40 mbps download speed or even higher.
Why is the performance of the Ethernet adapter so poor? Any ideas? Is there something that I could do to get a download speed close to the 100 mbps that the 10/100 Ethernet interface should support?
And finally, this is to Samsung guys, why is a Smart TV not shipping with a decent Gigabit ethernet port if they are even included in cheap network switches? It is very frustrating to buy an expensive product like this one just to find out that it is so limited in its performance.
