Hi @mattmoretti1, welcome to the Sonos Community!

So we can get a clearer picture on how the network is setup, mind letting us know the make/model of router, and if there are any Access Points or wireless extenders in use?

Are any of the Sonos speakers connected via Ethernet, or are they fully wireless?

It may also help to turn off Private Addressing in the iOS settings. Let us know how you get on :)

Eero Pro router with two beacons.  Speakers in question are fully wireless, but appear to be connected to the main eero base station if that matters.

Turned off private addressing but still not showing up when I try to add an accessory.  I could wire it into the router but unfortunately the eero base station only has two ports and I need the free port for a hue bridge.  But if that’s the solution I’m happy to get a switch and can hardwire in a few more devices.

Got it - if it’s possible to temporarily connect via Ethernet, to see if we can get the initial connection completed, that would be ideal.

If not, then another option would be to temporarily power off any secondary WiFi nodes to ensure that the iOS device and your Sonos speakers are connecting to the same point.

If you’re still having trouble, it may also be worth reaching out to our Support Team via live chat or phone call, as they have more tools available for live troubleshooting :)

Still no luck in hardwiring or disconnecting the router beacons, tried to call the support team and they said “we deal with troubleshooting with the Sonos app” before putting me on hold a couple times and walking me through some steps after submitting some diagnostics but they didn’t seem to have any answers.  Anything else that might work?
