Did you send something by e-mail? If not and you are referring to your posts in this thread, no one from support has been involved in this thread. The people you’ve been talking to are just users like yourself.
I looked at the GUI you posted 4 days ago. Everything looks as it should.
Your Nucleus screenshot shows that you have the DHCP method of obtaining its IP address selected. I strongly suggest that you keep it that way.
The method assumes that you have a DHCP server running in your home network, which gives out (and renews) IP addresses to the devices in your network (your Mac, iPads, and any other device that requires an IP address).
The DHCP server usually lives in your router. I don’t know whether the Orbi mesh base station has also the possibility to have a DHCP server. In any event you must only have one DHCP server running in your home network. It sounds as though something has gone wrong.
I suggest doing the following steps in order:
Turn off your Nucleus.
Reboot your router
Reboot your Orbi base station
Turn on your Nucleus…
Wait between steps for each device to fully boot up (e.g. your router must be fully up and running before turning on the Orbi base station)
Thank you for providing that information and screenshots. I have enabled diagnostics for your Nucleus and I believe I have found the cause of the issues. Unfortunately, it looks as if your Nucleus Operating System M.2 SSD is experiencing hardware failure and the Nucleus unit needs to be sent in for service.
I see that your account is registered outside the United States, so in this case, it would be best to let your Roon dealer know that the unit is having hardware issues and that they should work with our local area Roon distributor to service this unit. You are welcome to point them to this thread and they can reach out to us via our dealer channel if they have further questions, thank you.
