Home Hubs - Disconnected

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 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.

The above tips are very useful. The OP could try temporarily disabling the 5GHz band on the router to see if this eliminates the problem. This has helped to isolate intermittent Wifi problems with Homepods, The ATV seems to be more tolerant of wifi issues but it is a relatively simple test to try (subject to access to router settings).

There is likely to be more potential for interference at 2.4 GHz, because this is the frequency that common household devices such as cordless phones, baby monitors and the like commonly work with. However 5 GHz is far more prone to being blocked by relatively lightweight objects such as studded walls and doors, and it would certainly be worth trying the set up with 5GHz being enabled.
