Surely it matters. for all other devices as they are working as expected, only new Apple TV 4th Gen not working, the only reasonable explain is there is a problem with the Apple TV itself. As an engineer, I would say the troubleshooting is to ensure all other known working devices works in that environment, so I get a certain level that there is something wrong with the device itself. Of course not 100% sure, but I would say I am 80% sure it's the Apple TV's problem, if I want I can even open Wireshark to see what's going on there with the packages, and write a blog about what I find. But I just don't have that kind of time.
Also, after googling around, I found tons of people having the same issue.

You can find some comments there.

I’m hoping it fixes the awful network bug that causes packets collisions all over certain networks and causing all devices on the network to slow down severely.

@ikrupp215 @mikhailt There are SEVERAL threads on the new Apple TV forum – check it for yourself. So while YOU may not have heard of this bug, it doesn’t mean at least some of the millions of other customers who purchased an Apple TV has not experienced it. Additionally in digging through the tvOS beta 9.1 release notes it would appear that this entry in the networking section of the release notes is a red herring:
“Explicit Congestion Notification (ECN) is now enabled by default on Ethernet and Wi-Fi. This is designed to reduce network delays and reduce packet loss.”
It would be no wonder why some networks with a lot of of clients (specifically 1Gbps clients) would have some issue depending on the makeup of the network. If ECN isn’t enabled by default (like it should be) then it could leave the door open to these kinds of packet collision mitigation issues. But hey you’ve never heard of it, so it’s not true right? So not true that this exact issue and symptoms are mentioned in Apples software update release notes. :rolleyes:
@richslin That is exactly what led me to start troubleshooting it and look for answers in the first place. Plex wasn’t working well no matter if I was on wired ore wireless then I tested it against other devices with the same app on my network to rule out it being an actual network issue. I then tested other apps like netflix and hulu and they are exhibiting the same symptoms so that also rules out it being an issue with the Plex app itself. As stated above though I believe it has to do with ECN not being turned on by default (which is odd but probably just missed in the initial aTV release) and they are fixing it in the 9.1 release.
So, to answer @BeavertonMac's question, I would say it's a bug of new Apple TV. Hopefully will be addressed by Apple soon.
