I changed internet providers. My appletv worked for a couple of days with the new service but now it has disconnected and won’t connect to wifi. I have reset it and everything else. I am not able to remove the wifi and re-install it either

Greetings adee253, 

We’re going to provide a link with steps to take for troubleshooting Wi-Fi on an Apple TV device. If the situation differs, and instead we’re working with the Apple TV app via another device, do let us know which device we’re working with. If your Apple TV can't connect to Wi-Fi 

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.

Thanks.
