Apple 4K tv throttling my Mbps download speeds

So a couple of interesting facts or for me more frustrations lol… tonight I decided before I reset everything and reboot everything I wanted to try a few more tests both wired using the exact same Ethernet the ATV 4K is using and then Wireless and do this with three different laptops, the ATV 4K, and a Kodi Box running raspberryPi. So first all of the non Apple devices reported download speeds via wired in the 380Mbps, then on Wi-Fi 320Mbps, which again is exactly what I would expect as I am paying my ISP for that speed. Then I plug in the Ethernet back into the ATV 4K and ran the test and it’s results again the same as last night averaging 35Mbps. Then surprisingly I disconnected the Ethernet and connected to my 5g wireless signal and ran the test, that resulted in 390Mbps. How in the world does my Wi-Fi produce that speed within ATV 4K but then switching back to wired Ethernet connection it reports over and over low 30Mbps. I went back into my Luxul router settings nothing at all is jumping out at me mainly because I am not a Network engineer lol, but I made sure the QoS was disabled, the UpNp was disabled. I rebooted the modem and the router again just to make sure that was not it…..I connected to ATV 4K and while connected to Wi-Fi disconnected and forgot the network then rebooted and connected Ethernet. No matter what I tried the results remain the same download speeds of low 30Mbps. And I also retested my laptop on the same Ethernet after all the reboots of everything and got desired results 385Mbps. Sorry for the long post, but also reset and deleted everything within the ATV 4K then after set up I made sure not to share anything and not to download anything including screen savers etc. Still same slow download speeds while wired, but changed to Wi-Fi one last time and again reported 385Mbps. Very strange that the Gigabit Ethernet port is not producing the download speeds It should be and now I am just at a loss for what to try next.

Fantastic, thank you for verifying that you are able to get your expected Download speeds within the Apple 4K TV. I agree that 300 to 400Mbps should be a none issue for this device especially when all Network hardware including the cables being used all support Gigabit Ethernet, and since I can prove I am getting my expected ISP plan download speeds from the same location using other devices this tells me that there must be a software or hardware glitch with the Apple 4K TV I just purchased (which happens) I just appreciate your time with verifying you were able to use the same device and pull your expected ISP Download speeds.

Ahhh maybe that is it, I will look at it again tonight. It is a new device and I did know that it would download those screensaver and something else (forgot at the moment) but would have thought I would notice or be made aware that the system was in process of downloading and then if that’s the case I easily understand the slowness due to competing resources. Good thoughts, thank you very much and will keep an eye out if this is the case. Any idea how long a new device takes to download all the new files? I know that’s a loaded question but wondering if it will download while in sleep mode, or assuming like I mentioned the network speeds for downloading via Ethernet should be >300Mbps. Thanks again for your thoughts.

Setting is and was disabled..thank you
