Don’t do Tidal or Qobuz. Will take out the iPad and Android phone Endpoints.
CMD shift 4 actually to make a selection.
Yep. 5 opens the screen shot interface.
The more tests that I do, it’s beginning to look like a conflict between the Roon software and the BT Hub.
Yep. But it would be worth narrowing it down a bit if you can.
Is there a way to Wi-Fi the Nucleus?
Not directly, but you could use the method I outlined above to wire it to the imac.
I have some experience of BT hubs (I worked for the company for 40 years) and while they are generally pretty good at what they do they aren’t perfect.
While recently sorting out problems with my broadband & Wi-Fi I eventually got a replacement BT SmartHub2 after connecting up & configuring the device I found I was having even more problems with my Mesh Wifi…….to cut a very long story short the brand new Smarthub proved to be faulty and a second replacement resolved my problems (Interworking between BT Hub & BT Wifi Discs). This may, or may not, be relevant but don’t trust the new Hub, try borrowing another to prove yours is good.
REIN is definitely a possibility but usually very difficult to prove unless you can pursuade the openreach people to send one of their special faults people out to investigate (e.g. a common problem in rural areas is electric cattle fences causing interference).
If you lived closer I could lend you a known good Hub.

Just been googling around to see if I can find anything relevant re the HH4 and Roon, and didn’t find much. The only thing I did find that might be worth trying is to turn off Smart Setup (if you have it turned on) as it’s been known to cause problems.

Not WiFi, but you could try to use the USB Ethernet dongle with Nucleus instead of the built-in network port.
I see only one way to move forward.

Thank you for your reply. We have an Exchange Line, which is why we have a HH 4 Type A.
I agree, there is nothing to say that the replacement Hub is also faulty.
I have totally disconnected the Nucleus, and put the Roon Core on my iMac, with a wireless connection, thus taking the Nucleus out of the equation.
Someone on another site (Naim Audio) has suggested connecting the Nucleus/Hub directly to the maintenance port of the OpenReach socket. Do you have any thoughts on that?
Will try it. Thanks
Well plenty of people on here might have a clue, so post anything you find. The Smart Scan you mentioned is intriguing, especially if you discover it runs every 15 minutes or so. Whatever it finds would be logged just before reboot commences (so look at that time stamped bit of the log) and might indicate what the issue is (if Smart Scan is initiating reboot). The regularity of this is very suspicious though.
There’s nothing to lose by trying but unless you have wiring to internal extensions all you will prove is that the few components in the master socket are ok.
If you have extension sockets fitted it will prove that they aren’t the source of the problem (removing the faceplate of the master socket will disconnect extension wiring & give access to the main “maintenance” port which is connected directly to the telephone line).
The newer smarthub2 comes in two variants one having four ethernet ports (FTTC) the other has 3 ethernet & 1 wan port (FTTP), however the latter will also work on FTTC so if you can borrow one to check your system out you might resolve the problem or at least eliminate the Hub as the cause. I have the FTTP version which is working fine in my FTTC copper line.

I am now totally confused.
I hardwired the iMac to the BT Hub and installed the Roon Core. Four hours later, no dropouts or Reboots. Rock solid.
Four hours previously, the iMac was just Wi-fi connected and had four dropouts/Reboots within 90 minutes.
I will now reconnect the Nucleus to the Hub to see what happens.
I know this surely can’t have anything to do with it, but I connected the iMac to port 4 on the Hub. Previously, the connection was ports 1-3.
Port 4 on the Home Hub is the only Gigabit ethernet port - ports 1-3 are only 10/100 mbps…

Fingers crossed.

Would port 4 have a different outcome than ports 1-3?
The Nucleus has a gigabit ethernet port, but I would have thought it would be able to negotiate a stable/reliable connection to one of the 10/100 ports on your router, even though your recent iMac to port 4 test would suggest otherwise. Let’s hope this is the solution.

I’ll try later. Thanks
