Thanks for the update, @Antoine_Remy, and yes, what you’re describing with the extender is very relevant.
The pattern you’ve described is a strong match for a failing network link rather than a failing Nucleus. The Nucleus came back after a power cycle, stayed reachable long enough to start an update, then disappeared again, and in the same window the extender it’s plugged into is showing no lights and making an audible pulsing noise.
It’s also worth knowing that your Nucleus isn’t really wired in the way it looks. The cable runs to the extender, but the extender’s own link back to the main router in the basement is wireless. So your Roon Server is effectively sitting behind a wireless hop, and that hop is the least reliable part of the chain. That’s a setup we’d want to change regardless of what the extender turns out to be doing.
Two things to try, in this order:
1. Get eyes on the Nucleus. Connect the Nucleus HDMI output to a TV or monitor and send us a photo of what’s on screen. This is the single most useful thing right now, it tells us whether the Nucleus is booting normally, whether the update completed, and what IP address it believes it has, none of which we can see from our side while it’s off the network.
2. Take the extender out of the picture. Move the Nucleus down to the basement temporarily and run an Ethernet cable straight into the main Verizon router, or run a long cable up to it, whichever is easier. Your streamers will still find it over Wi-Fi as long as everything stays on the same network. If the Nucleus becomes reliably visible again, we’ve confirmed the extender, and that’s a call to Verizon for a replacement rather than anything to change in Roon.
A couple of details that will help us as well:
- Log into your main Verizon router and check the list of connected devices for the Nucleus. If it appears there with an IP address, the Nucleus is alive and the problem is purely reachability. If it never appears, the extender isn’t passing it through at all.
- Let us know whether the extender is set up as a true extender/bridge or whether it’s handing out its own IP addresses. If it’s running its own network, your Nucleus and your streamers may be on two different networks, which would prevent Roon from seeing them even when everything is powered on and healthy.
One note on the update: if the network dropped partway through, it’s possible the update didn’t finish cleanly. Please don’t retry it until the connection is stable, a second interrupted update is a good way to turn a network problem into a software one. Once the Nucleus is on a solid wired link, we’ll confirm the OS version from the Web UI and re-run it properly if needed.
