AppleTV 4 kills my internet connection

Intermittent problems are often a result of interference. Interference can be caused by other wifi networks in the neighbourhood or from many household electrical items.

You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items that cause interference.

Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate (which may help where interference is present. You might also try moving the Apple TV away from other electrical equipment.

There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software or from device to device, so just because it worked before or works with a different device doesn’t exclude interference as a problem.

You may also find some help on this page, where I’ve collected some of the more unusual solutions to network issues.

I understand that some of the suggested software (whilst once free) has become pay-ware, I suggest you look around, you may find free alternatives.

I have a similar issue. Internet works only for a while when the Apple TV 4K is connected through Ethernet to my router/modem (did not have the issue with my previous Apple TV. After a while, I loose internet. And not only for the Apple TV, I loose internet on all my devices (wifi and ethernet). If I restart the Apple TV, I get internet back. I can get it back if I restart the router/modem too.

I observe the issue with iOS 11.0 and the public beta 11.1.

And we are not alone. Check out this thread: https://www.reddit.com/r/appletv/comments/721tlq/apple_tv_4k_ethernet_issue/

Apparently some guys found a workaround by placing an Ethernet switch between the Apple TV and the router. Hardly a solution though.

Test on another network and/or take to Apple

This is very strange. It seems like your Apple TV is doing something that causes the ISP's router to disconnect it. Difficult to imagine what that could be. It is certainly not the normal experience of Apple TV users.

Are you in a country that restricts access to certain sites, e.g. China?

Are you doing anything unusual on your network, like static IP addresses, etc.?

Are you using a VPN, unblocker, etc.?

Does this happen with a specific app, or with any app?

Hi. I'm surprised that you've changed both ISP and router multiple times without any change.

What type of physical internet connection do you have? Is it cable TV, optical fiber, satellite, cellular, wide-area radio, or what? Were all the ISPs using the same type of link?

I'm having this same problem with my new AppleTV 4K. My whole internet goes down until I reset the router or unplug the Apple TV (wired). Have you found a solution?

The longest my network has stayed up with the AppleTV connected is about 45 min to an hour.
