I have a Nucleus rev b that refuses to appear in my network Roon device list. I was using it as an end point only but it started to go missing. Rebooting the Mac I have core on would eventually get it back, to show in the list. But now it’s gone for good. I even tried to launch it as a core but I can’t. It’s a good looking brick. What can fix it?
Describe your network setup
Comcast modem, Cisco gigabyte switch, 8 ports, Eero mesh with two devices. However, I have all the Roon core and nucleus hard wired with cat 5 or 6 cable.
Fellow user here, I would suggest plugging a monitor up to the Nucleus and see (capture a pic) of what is displayed on the screen when you start it up. If it is working okay it should display it’s IP address.
I am not seeing any Nucleus tied to your account at all, which is likely due to the Nucleus not having been active for more than 30 days. I would second the suggestion of trying the HDMI test, we also have the following troubleshooter specifically tailored for Nucleus hardware issues:
I have done all that troubleshooting up to the point of somehow connecting to the Nucleus. Nothing in that routine worked. Also, when I look at my entire network on a computer, there is no evidence of the Nucleus, either in wifi or ethernet. I guess that I could plug an HDMI into it and see what comes on the screen but what good does that do?
ok, I plugged an HDMI into the Roon and it simply says Searching for network address. thats. it. And. yes, this is a good ethernet cable into a fully functional switch that is actively up on my LAN.
Hi @charles_pick,
Since the Nucleus is unable to get an IP address assigned to it we should reset the network settings on the Nucleus. You will need a USB keyboard to do this. Here are the steps.
Connect the Nucleus to a monitor or TV via HDMI
Connect a USB keyboard to the Nucleus
Press ENTER
Type resetnetwork
Press ENTER
If you are still unable to see your Nucleus on the network after that it would signify a hardware issue with the Nucleus’ ethernet port. In that case you can submit an RMA through the link that @noris provided to you.
