Mind you I only have a few dozen Samsung's to date but if I follow the distance rules (20 feet or less) then it's fine. That seems to really surprise folk as they expected a TV's WiFi to be on par with laptops and such. It's not.

You can see the same complaints on other makes so what to do other than drop the distance or just wire it so there is no drop?

That won't change the issue of Samsung's services. Why they made it so the TV had to check in with Samsung to play Netflix is something that will dog them for years.
