I am having the same ATV 4K stuttering problem reported by others. Internet connection through Comcast is fast but ATV goes blank for a second every couple of minutes particularly when streaming content from Apple and from Hulu.

The download speed is 540MB. I tried these steps above but the buffering problem continues.
Are you using any third party VPN apps and or additional network security over and above what your router's default settings are?
