Description of Issue
My Nucleus + (Revision B) has apparently been off-line since early December 2023, which is the last time it completed an automated Roon backup. (I’ve been away from my home off and on for the last year: this is the first opportunity I have to try to resolve the problem). The Nucleus is not findable on my household LAN; I therefore cannot access music contained on its internal drives. The Roon Core on the Nucleus does not come up as an available Core in the house (I have been able to use a separate Core on my laptop, which I can use to play music files contained on two NASes, but not off the Nucleus storage). I do not know if this is a software or a hardware issue, perhaps something that emerged from an update pushed out at that time—I’d appreciate advice. It had worked smoothly on the system before that. I bought this Nucleus direct from Roon, and have tried all of the sensible remedies, i.e. restarting everything, etc.
The Nucleus is connected via cable to a TP-Link inter switch (model TL-SG105), and from there to an Eero home internet system. The modem/router for the home system overall is a Motorola 24 X 8 Cable Modem Plus AC 1900 router, model MG7700.
Any lights on the Nucleus (power or ethernet)?
Have you tried rebooting everything?
After above checks two more things to try:
Can you see the Nucleus on the Erro app? Is it assigned an IP in the Erro app?
Next is tyr connecting a monitor/TV to the HDMI and then reboot the nucleus and see if anything comes up on the screen.
Hi @Scott_Klein,
Thanks for writing in to ask us about this issue. @bearFNF offered some good suggestions here. Please try them and let us know the result.
The Nucleus does show both a power light and an ethenet light. I had already tried rebooting everything, to no avail. I can not see the Nucleus on my Eero app-- I believe that I used to see it by name. (The app does note on unnamed wireless connection to the appropriate hub, but the Nucleus ought to show up as a wired connection.)
I connected my Nucleus to a TV set using an HTMI, and rebooted as suggested, but the TV only reads “No Signal.”
Scott, you may have cooked your Nucleus Plus motherboard from weeks or months of constant audio importing and metadata matching.
If you have 30,000+ albums in WAV format with inherently minimal metadata, Roon is going to have a terrible time trying to identify those albums.
A double whammy, if thousands of those albums have HTOA files, those files are unidentifiable and pointless 99.9 percent of the time. They are a couple hundred milliseconds of digital silence and are inappropriate for Roon use — except for those very few albums known to incorporate actual “hidden track one audio” in HTOA files. See example:
