Apple TV 4K (3rd Gen) Ethernet Issue: 'No Network Detected' Error Resolved with Switch

SOLVED FOR ME and hopefully can be for you too.

Issue: Frequent/random error pop-ups: “No Network Detected" while connected via ethernet.

(Error pop-ups DO NOT appear while connected via WiFi)

Apple TV 4K (3rd generation) Wi-Fi + Ethernet - Part MN893VC/A - Model A2843 (128 GB)

tvOS: 18.1 - 22J580 (December 16, 2024)

Router: XFinity Gateway/Modem - Model TG4482

So I can’t take full credit for this as I came across it in another thread, and it’s not ideal, but it’s certainly a workaround.

Solution: I added a switch between the Apple TV & Router.

Apple TV connects to the switch, the switch connects to the router.

That’s it.

I used a cheap D-Link 5-Port Gigabit Unmanaged Desktop Switch - Model DGS-105

From what I’ve read, the Apple TV ethernet hardware doesn’t play nice with certain routers and many of the routers seem to be the XFinity Gateway/Modem (in my case TG4482).

Before adding the switch, I could expect a pop-up every few minutes, but after adding the switch, I’ve not had a single one. However, there is one new thing, it happened just twice during 3 hours of streaming, and this might be completely unrelated to the switch, but while watching an episode of SILO on Apple TV+, the screen saver spontaneously appeared without warning or pop-up error. One press of the remote clickpad resumes the episode so it’s not a big deal and it only happened twice in 10 minutes.

My limited engineering knowledge offers that it’s a matter of hardware incompatibility. It’s a widely known issue that Apple won’t address, likely because the Apple TV works well for the majority but not for some and only with certain routers. But I could be wrong. A tvOS update became available yesterday (v18.1), I was hopeful that it might solve the issue, but it did not. I’ll keep monitoring and report back if relevant.

I get the same error message popping up at the most maybe 1 - 2 times a week. My Apple TV 4K is also connected via ethernet and I have always had a network switch in between my Apple TV 4K and the router.

So when I do occasionally get the error message I just ignore it since my steaming experience is not having issues when the message pops-up.

I'm on day 2 of streaming with the newly added switch between ATV and router and all is good. I've not had any "No Network Detected" pop-ups or other anomalies such as spontaneous screensaver appearances. If a pop-up should appear once or twice per week such as what you're experiencing, I still feel it's a win. I see a new tvOS update became available today 18.2 - 22K155 (December 18, 2024), I'll see if it addresses the pop-ups by temporarily removing the switch from the chain.

Side note, I consulted with an Apple Store "Genius" yesterday on a separate unrelated issue, I brought my AppleTV and asked if he was aware of any issues with the "No Network Detected" pop-ups. He referred to Apple's recall program and saw nothing posted. He also asked his manager and both of them claim not to of heard of it.
