Audio devices not showing on home network (ref#3JB1AA)

[Gus_Psarros]

Hi! What’s not quite right with Roon?

· None of the above quite fits

None of the above quite fits

· None of these quite match

Tell us what's going on

· My audio devices connected to my home network are not showing.

Tell us about your home network

· I have an Eero 7 mesh network, ATT fiber connected to their BGW620-700 gateway, Mac mini M4 pro, Tahoe 26.2

Hello @Gus_Psarros,

Thanks for reaching out — we’ll need a bit more detail to understand what’s happening here.

Could you please clarify the following:

1. Which audio devices are not showing up?

• Brand and model (e.g. streamer, DAC, AVR, speakers, etc.)
• Are all devices missing, or just one specific device?

2. How are those devices connected?

• Ethernet or Wi-Fi
• If Wi-Fi, are they connected directly to the Eero mesh or to the AT&T BGW620 gateway?

3. Where is Roon Server running?

• Confirming it’s on the Mac mini M4 Pro
• Is it connected via Ethernet or Wi-Fi?

4. Do the devices appear in Roon at all under Settings → Audio, or are they missing entirely?

Since you’re using an Eero mesh, please also check:

• That multicast / IGMP / mDNS is enabled on the mesh
• That there is no client isolation between wired and wireless devices
• That all devices are on the same LAN / subnet (no guest or isolated SSIDs)

Mesh systems can sometimes block or limit device discovery if multicast isn’t handled correctly.

Once we have these details, we can guide you more precisely.

Hi Vadim,

Answering your questions in order:

1. None of the devices are showing. I have the following devices:

• B&W Formation Speakers
• B&W Formation Wedge
• Lumn P10 streamer
• EverSolo streamer
• WiiM streamer
• Marantz receiver
• MacAir

2. Depending on the device, it is connected either by Ethernet or WiFi. All devices are connected to the Eero Mesh

3. Roon Server is running on my MacMini M4 Pro. It is connected via Ethernet. The WiFi is off. I tried to see if switching to WiFi would fix the issue, but it did not. Up until 7-10 days ago I did not have any issues.

4. All of the devices are missing entirely. The only Audio device that shows is the MacMini.

5. I do not see an option for multicast/IGMP/mDNS. Also, it appears all of my devices are on the same LAN/subnet, but I am not the most educated in this area.

Thanks for your help.

Hey @Gus_Psarros,

recent macOS updates have tighter (and more obfuscated) network security settings than preceding macOS versions.

Can you please navigate to macOS System Settings > Privacy & Security > Local Network, and make sure Roon and Roon Server are allowed.

If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.

Thank you!

[Gus_Psarros]

Hi Benjamin, I followed your steps and it worked. However, when I went to restart all of the audio connections disappeared. This is not a viable, long term fix. What do you recommend?

Hi @Gus_Psarros,

See here:

macOS Sequoia Roon Server / Device Connectivity Issue, Roon Status & Workaround

The Issue macOS Sequoia (version 15), has tighter (and more obfuscated) network security settings than preceding macOS versions. This is causing problems during Roon updates; despite being previously enabled during the Roon installation MacOS, after an update MacOS is denying access to the network (yet retains displaying all is well). Roon Status Roon support and product team are aware and are working a fix, which I understand is quite involved (I have no timeline for that, sorry). The Workar…

Unfortunately, this is the only option for now. Our team is working on a long-term fix, and we’re also hopeful that Apple will address the issue on their end in the long term.

[Gus_Psarros]

Ok, thank you for your help!

Hi @Gus_Psarros,

Thank you for requesting we revisit this case again. We understand you’re still experiencing limited connectivity or dropouts on your Roon Remotes and endpoints.

We noticed you have an Eero router setup listed in your topic description. It’s possible that the Eero has delegated some of your devices to a separate subnet or class-C block (which it will treat like a separate VLAN).

At your convenience, please try the steps in this article and let us know if it helps. We’ll watch for your response.

Troubleshooting Eero Mesh Networks with Roon

[Gus_Psarros]

Hi Connor, I tried the troubleshooting items you suggested. None of them helped. What else do you recommend?

[vadim]

Hello @Gus_Psarros

I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.

However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.

First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.

[Gus_Psarros]

Hey Connor, The issue is ongoing. I haven’t had access to any of my audio zones for well over a week. The only time I can listen to my library using Roon is when I am in the car using ARC. None of the audio zones are available within my house.

Hello @Gus_Psarros ,

Sorry to hear of the troubles. Have you tried to reboot your network setup yet? I would try this as a first step. Looking over the diagnostics gathered from your Roon Server, it appears you are getting “No route to host” errors, and something is preventing Roon from communicating with these devices. Are you using multiple networking interfaces on the Mac? Is the behavior the same if you disable all but one interface?

[Gus_Psarros]

Hi, I have rebooted my network numerous times. I also tried switching off my wireless and connect directly to my network with a lan cable. Tried being on wireless and wired at the same time. Is this what you mean by using multiple networking interfaces?

[benjamin]

Hey @Gus_Psarros,

Typically, a networking interface is a router or mesh node that can sometimes assign different IPs/subnets depending on the network setup.

That said:

@benjamin

Can you please navigate to macOS System Settings > Privacy & Security > Local Network, and make sure Roon and Roon Server are allowed.

@Gus_Psarros

I followed your steps and it worked.

Is the above still the case? While tedious, does this process still allow you proper access to your audio devices?

Thank you!

[Gus_Psarros]

Hi Benjamin, Both Roon and Roon Server are allowed.

[benjamin]

Hey @Gus_Psarros,

Apologies for the long delay in following up. After reviewing your account admin, it looks like many audio devices have been recently active from your Roon Server.

Are you still having issues here? If so, please provide more information about which audio devices you’re having issues with currently.

Thank you!

[Gus_Psarros]

Hi Benjamin,

Thanks for reaching out. My audio devices appeared again. Not sure if it was due to your latest release or because of IOS 26.3. I don’t plan to restart my Mac mini anytime soon as I am afraid I will lose the audio connections again. As of right now, things are good and this support ticket can be marked as complete.
