Apple TV 4K, "No Network Detected"

If you want to use Wi-Fi, make sure nothing is plugged into the ethernet port.

Is the Apple TV 4K in the exact same location as the Apple TV (4th generation) was? E.g. different rooms may have differences in signal strength or interference.

Apple TV 4K (brand new) constantly shows "No Network Detected", dropping videos constantly.

If it drop videos constantly, then I presume that these videos do start over the network, so there is in fact a network functioning. So, it appears there are certain unnamed apps that lose their connection during playback and give this message. Which app? Is there any other app that still functions over the network?

Are your network settings on the Apple TV set to Automatic IP and Automatic DNS?

I am having the same problem - and it just started about a week ago. Nothing has changed in my environment, and all of my other devices sustain connectivity. Essentially, the video drops, I hit menu and then play and it comes right back. It's SUPER annoying.

I'm facing the same problem and I don't know why. With the same wifi network, in the same room, I can connect to the internet via my ipad, iphone, macbook normally without any interruption. So it cannot be a network issue. Why does this issue only happen on my apple tv 4k?

Interference can be extremely local. Electrical wiring, power cords, metal cabinets, a refrigerator, etc.
