Apple TV 4K (1st Gen) Ethernet disconnects

[staray51]

When the Apple TV 4K is turned off, the Ethernet port disconnects then switches to 100Mbps. It then starts disconnecting and reconnecting constantly. After a while, it stays disconnected for hours before the interface comes back up, but only stays up for a minute or two and then disconnects again. When I power on the device, it now won't even connect at 1000Mbps but instead connects at 100Mbps. Note: at one time it would connect at 1000Mbps.
I have a Cisco 2960G gigabit managed switch and I can look at the logs and see the constant flapping while it is off/sleep.
My other 2 Apple TV HD models do not have this problem.

This is not a cabling issue or port issue on my Cisco switch. I tried moving the 4K to the port where one of my Apple TV HD is connected,
and the problem moved with the 4K. Also tried assigning a static ip address.

I noticed in another post "Extremely slow Apple TV 4K 2nd gen" that they saw this behavior with the newest Apple TV 4K.
Is this normal behavior with the 4K models or did his behavior show up after an tvOS update? Currently running latest code 14.6

Other than trying a reset I’m not sure what else to suggest.
However ATV4K only requires 25mbps to stream 4K so even with just 100mbps you’ve got more than enough bandwidth for what the ATV needs.
Personally unless it’s not actually connecting to the internet at all then I wouldn’t even worry about it.

Thanks for the reply. Yeah, I have been putting up with it but it just bugs me that it's a Gigabit interface but won't negotiate to that speed. I did try the reset but no luck. I really posted this note to see how many people are also experiencing this behavior on the ATV 4K (2021) model. I may have a bad interface port on my model.
