Apple TV 4K sleep mode problem

Hi there Airlung,

If your Apple TV is repeatedly disconnecting from your network, you'll want to try these steps to see if they resolve the issue for you:

1. Check that everything is on, connected, and in range

Make sure that that your internet router is connected to your modem and that both are powered on. If your router and modem are combined, make sure that the device is powered on. 

If possible, keep your Apple TV and Wi-Fi router in the same room, but don't place your Apple TV directly on or within a foot of your router. Try to avoid physical obstructions in the path of your wireless signal, especially metal surfaces. If your Apple TV has an Ethernet port, connect your Apple TV directly to the modem with an Ethernet cable for the best experience.

2. Restart your Apple TV, router, and modem

After you restart each device, see if you still need help.

On the Apple TV menu, go to Settings > System and select Restart.

Unplug your router and your cable or DSL modem from power. Then plug them back in.

3. Use an Ethernet cable and check for software updates

If your Apple TV has an Ethernet port, try connecting your Apple TV directly to your router, or cable or DSL modem using an Ethernet cable. Apple TV connects to internet with either Wi-Fi or Ethernet. When you use an Ethernet cable, Apple TV automatically uses that connection instead of your Wi-Fi network. 

Join your network and check for software updates. Go to Settings > System > Software Updates. If there's an update, install it. Then unplug your Ethernet cable and try to join your Wi-Fi network again.

Although this link references a Wi-Fi connection rather than ethernet, the steps should still be helpful. You'll find this information here: If your Apple TV can't connect to Wi-Fi - Apple Support

Take care.

It is not an isolated issue, i have the same problem (Apple TV 4K 2022 Wifi+Ethernet).
