Internet radio stops when network busy


roon Nucleus connected to wired LAN and USB to DAC

Sometimes my network does not respond fast enough.
Then roon stops playing the internet radio.
When I start it again it continues.

This does not seem to happen when playing Tidal.

It seems that the internet radio does not buffer as much as the Tidal streaming, or it gives up sooner if it has connection retry or delays.

In the same situation my Mac Mini just continues playing the same internet station.

Hi @Flere,

Thanks for your report. Can you please let me know:

  • Which radio station this is and provide a link?
  • After approximately how much time does this behavior occur?
  • Note the exact local time in your country (ex. 5:31PM) that this issue occurs again?

Please let me know the above info and I can enable diagnostics mode for you account and take a look for any strange behavior under the hood.

When I came home this evening at 19:00 CET I started roon internet playing.,aac

In the next hour it happened a few times that the internet radio stopped playing and had to be restarted.

Stop playing means the play/pauze button switches from square to triangle and of course the music stops.

Also there is then a message above the bottom bar displayed which reads that the network seems to be unreachable and I need to check my network connection. Or something like that.

It happens sometimes also with other internet radio stations.

what are the DNS settings in the Nucleus web GUI?


I can send value by email.


Is there a way to change the Nucleus DNS setting?

(Mr Fix It ) #8

Yes you can set in the web page GUI. There is no secret for dns numbers try and


OK. Thanks.
But I am not very well into the networking stuff.
I can only set the DNS if I choose fixed IP.
Should I just fill in the number which are shown now, and only set the DNS to

Set the IP address to fixes as the same number it now…maybe key that reservation in your router too if you can. Add your router address and the 2 dns I mentioned all on one line with spaces between the 3 sets of numbers

Warning…messing this up can mean you might disable internet access on the Nuc and perhaps have to reinstall

Suggest you screen print your settings before you change anything so we can advice what’s most likely and your router model etc

(Mr Fix It ) #12

I just noticed your on nucleus…so seek help from your nucleus supplier…that what you pay them for

@Flere - Please don’t set a static IP for your Nucleus, this could cause some issues with being able to connect again if the IP is wrong or changes

Thank you for confirming the above information, I have enabled diagnostics on your account so our technical staff can get some more insight into what’s going on here. The next time your Core is active a diagnostics report will automatically be generated and uploaded directly to our servers.

Once that’s been received, I’ll be sure to update this thread and pass the diagnostics over to the team for further analysis.

While we are reviewing diagnostics on our end, can you please let me know the model/manufacturer of your router, model/manufacturer of any switches, range extenders, powerline adapters, ect?

This happens to me all the time on my crappy DSL network. I suspect that this is more of a global product issue than an individual support issue. My fix is to use Apple TV for radio when my DSL is congested. Apple TV always reestablishes the connection during network congestion and the content resumes again automatically after buffering. Roon just drops it and requires manual intervention.


That is also my view on the situation.
The apps on my Mac seem to buffer more and also auto resume once the connection is re-established.
Roon just stops and requires manual intervention.


Dear noris
Thanks for the support.
The problem did not occur.
The moment it happens again I will note the timestamp and let you know.
