Apple TV constant buffering

Seems like a home network issue, not necessarily a device issue.

• Restart both your router and the Apple TV box.
• Make sure DNS is set to Auto .
• If on Wi-Fi, try Ethernet.
• To see a current status of the network get a report from iStumbler, NetStumbler or similar. Look for signal strength, noise, nearby networks, overlapping channel use.
• Test on another network.

My Apple TV constantly buffers as well. It does it with any app and it is definitely not a home network problem. I don’t have any problems with my Roku device, or my computer. It is only the Apple TV. I even switched ethernet ports and cables between the Apple TV and the Roku and the Apple TV still has problems and the Roku works perfectly. This is all on ethernet mind you. Anyway to fix it? Thanks

My Apple TV A1625 is also constantly buffering and now some live streaming apps (CBSN) only load pre-recorded content. The app works on my TV and iPhone CBSN apps. Netflix seems to have more buffering events than other apps. I bought a new TV because it wasn't internet speed; bought new routers and ATT fiber gateway. Totally didn't occur to me that the problem was with the Apple TV device.

Also significant buffering with Apple TV’s. I do have Verizon 5G internet in home with 3 Google nest mesh WiFi units. It is only recently got bad. Am getting about 200 mbs which is not bad. Is interesting that I power ATv down, it does reboot good for a while. Vz 5G is good.

Ughhh me too! So much pixelization and buffering, feed still at 550 mbps only occurs on WiFi and only on Apple TV not Roku anyone have any fix ideas? Do I need to scrap my 4K Apple TV and go with a $20 Roku stick to fix this?!?!?!

This started for me on only one of the Apple TV's, and only since tvOS 15.2 update. It's definitely not the network.

My apple TV is also constantly buffering. It's not the network because when I watch the same programming on my MAC is doesn't buffer. Model # A165 32GB OS 15.2

Same with me

When I switched my wifi to the 5G signal the problem resolved.
