I have an issue where the internet drops when I plug the Ethernet in. As soon as I disconnect the Ethernet cable, the internet comes back on.

Network settings show the Ethernet is connected (ruling out port failure)

The Ethernet cable works in other devices (ruling out cable failure)

I have power-cycled my router, switch, ATV and modem.

Any ideas about what this could be or how I can troubleshoot this, please?

Hello! I have an Apple TV 4K 3rd gen that's giving me some serious issues with the Ethernet connection. I currently have it set up with a static IP and set to go to my adguard home for DNS. Typically it works fine, and has for months, but all of a sudden about a month ago it started to just stop working mid stream. I could solve it with a full restart but it's getting more frequent.

Essentially what it is doing is acting as if it's not connected. Apps say there's no internet but the network still shows as connected, and I'm unable to ping the Apple TV from any device.

Troubleshooting attempted so far:

1. New Ethernet cable

2. Changing IP from static to DHCP

3. Plugging Ethernet into a new port on the switch

4. Plugging Ethernet directly to router

5. Plugging Ethernet into different switch

6. Plugging Ethernet into different router

7. Connecting device via Wi-Fi

The issue is resolved when the device is on Wi-Fi, even with the same IP and DNS settings. As you can see I've tried just about everything, and nothing is working. I've seen there are a lot of similar posts, but nothing with a definitive fix. If anyone has any ideas I'd love to hear them!

i tried restarting the apple tv and my router , I tried another Ethernet cable and it still doesn’t connect ..how to fix this ?

I want to connect my Apple TV via Ethernet. I have Ethernet outlets throughout my home so it was pretty simple to connect a cable from the outlet to the Apple TV. But after doing this I don’t seem to have internet connection. Is there an additional step to this I’m missing? I’ve tried restarting the Apple TV and my modem/router without any luck.

Going into network setting it says Ethernet Connected. It is also showing my IP address, Ethernet address, and Subnet Mask number. Going further, both Configure IP and Configure DNS are set to Automatic. Would all this not indicate that I am connected to Ethernet? So why no internet?

Edit: thanks for the comments. I continued to troubleshoot and figured out the issue. It was not the Apple TV. It was not connected via Ethernet. I had to move around some network connections in my main panel and my modem/router.

My Apple TV 4K (2nd Gen) is connected with ethernet. Now I am not able to use my iPhone remote control app which is obviously on WiFi. I can use the iPhone remote app only when Apple TV is connected via same WiFi. My tvOS & iOS are updated on 18.1 versions. I’ve already tried rebooting, unpairing & repairing iPhone with Apple TV 4K. Any help is greatly appreciated

Update: I feel pretty dumb. I tried a different port on the router and it works now. Thanks for those who suggested I do that.

I hard wire to Ethernet every chance I get and have no issues with any other devices in my house but I was noticing constant errors and buffering when streaming video from various apps on the new Apple TV. Then I started getting random disconnect notifications from cameras tied into HomeKit. They are perfectly fine in the manufacturer’s app and reachable outside of HomeKit when this happens. Also a similar issue with Ecobee devices losing contact with HomeKit. My PC, PS5, and Xbox are hardwired to the same switch connected to my router and consistently getting 600+ Mbps download.

Did a speedtest on Ethernet and was only seeing max 92 Mbps on the Apple TV and over 360 on WiFi. Haven’t had it running on WiFi long enough to determine if that’s the fix action for my intermittent issues but I definitely found the speedtest results disappointing. My Ecobee stuff immediately started working in the Home app once I switched to WiFi so that’s a good sign. Previously, I had to disconnect and re-add it to HomeKit.

I've seen a few old posts regarding ethernet port hookup causing problems to internet.

But I'm wondering if someone can explain to me why this would happen all of the sudden, when i've had the apple tv for months and havent had an issue before with ethernet hookup.

Was beginning to think it was my 5-year-old or so modem/router netgear. But after a lot of troubleshooting, I realized I would reset the modem and the internet would work just fine on all devices, until I turn on apple tv and immediately I lose internet access.

Hi everyone. I'm relatively new to the ubiquity world and a newb in general when it comes to network and the lingo. I have a couple Apple TVs that suddenly show "no connection" via ethernet. I'm running a UDM7 to a USW Pro max 24. I know it's not the cable because I can plug in my xbox to that same cable and port and it works fine. I've have other ATVs in the house that work fine (those might be newer models if that matters). The two that are not working show as disconnecting on different days about 2 weeks ago. I'm 99% sure I wasn't messing with any settings those days. Most settings are default, I have not set up anything fancy like multiple networks. The Wifi connection seems to work fine on the ATVs if I switch that. They both definitely worked at one point, and I can see the device name on the port but it is grayed out with a "last seen..." on hover.

I see other people asking the same question on the internet over the past year or so but cant seem to find a solution. Can anyone recommend some things I can try?

Things I've tried:

- Restarting everything (router, switch, ATV)

- Different Cables

- Different ports on the switch, and a different Ubiquity switch altogether

- Switching linking speed from "auto" to "1gps" (found that in another post)

- Ading a "dumb" switch between the USW and the Apple TV. The port on the USW lights up (it doesn't if connected directly to the ATV), but I still don't get internet.

Thanks
