Haha so is it not good?
May be worth upgrading to 4K box? I believe it has rj45 port and a bit more meatier. Reviews suggests that it supports 4K streaming over wifi without any problems. So I guess for normal and HD use it will be spot on.
No chance wifi can support full bitrate 4K, it struggles with 1080p. Theoretical limits on wifi are great, but in the real world it just won't cope. For Netflix-quality 4K though, it's probably fine. 4K is a very short lived fad, HDR offers far more benefits for a much lower cost for content producers, and a higher quality product for the end user too. But I digress, that's another rant for another day
My ATV4 box is just about the best multimedia box I've used, but obviously you pay top dollar for it and it has limitations when you're trying to run hooky software/access pirate streams. For Plex and Netflix though, it's superb.
Exactly my issues too! No proper multi-channel audio makes it a very poor solution for people who have even a low-end surround setup.
