Sorry to hear your Nucleus+ is having network issues. Before we proceed to hardware replacement, could you try one thing: connect a USB-to-Ethernet adapter to one of the USB ports on the Nucleus+ and use that instead of the built-in NIC. If it connects successfully, this will confirm the issue is with the onboard network adapter.
If that does not help, or if you would prefer to proceed directly to hardware support, please reach out to our RMA department via the link below and select “Other” → “This issue is related to a physical component”:
Hello - A USB to Ethernet adapter got my Nucleus+ back on the network. Can the on-board NIC be repaired/ replaced? Should I be able to use the other USB port to connect devices and my back up hard drive with a USB hub? I’m having trouble now seeing my Kii Threes on the other USB port, I could put it on a streamer instead of directly connected to the Nucleus. It appears the USB to Ethernet works on either USB ports on the Nucleus. Thanks everyone for the help!
Glad the USB-to-Ethernet adapter got you back online!
Unfortunately the onboard NIC is soldered directly to the motherboard and cannot be repaired or replaced independently — a full motherboard replacement would be required. I would recommend reaching out to our RMA team via the link I shared earlier so they can advise on the best path forward.
Regarding your other questions:
USB hub — yes, you can use a powered USB hub (make sure it has its own external power supply — unpowered hubs often can’t supply enough current to audio devices like DACs and may cause detection issues)
Kii Threes — if they’re not showing up on the other USB port, try connecting them directly without the hub first to rule out a power issue. If they still don’t appear, let us know and we can look into it further
