Hello all,

I have been scratching my head for days setting up my Sonos Play:1 speaker to be accessible across VLANs on my home network.  Tonight, I seem to have stumbled on a strange fix: turning off the app’s access to Location data in the iOS settings.

My network is roughly setup like this:

• multicast VLAN + 2.4GHz wifi which contains Sonos and AppleTV
• guest VLAN + 2.4GHz wifi
• trusted VLAN + 5GHz wifi

With this setup I was able to control Sonos from the guest network, so I was pretty confident that my VLAN configuration was setup properly.  But, strangely I was unable to control Sonos from my trusted network.

I finally decided to configure my trusted wifi to use 2.4GHz and things worked!  This made me decide to plug my Play:1 in via ethernet.  I figured this would avoid any issues with wifi since it would be accessible on the network over the wire.

However, the problem persisted; the app would work fine on the Guest network, but it would not work on the Trusted network at 5GHz.

I found myself in the app’s settings page and decided to disable its access to what I thought it didn’t need: Location, Bluetooth, mic, and cell data.  All of a sudden the app was finding my speaker!  After a little process of elimination, Location was the setting that affected access to the speakers.  ‍♂️  I turn on Location data, the app stops working; turn it off, speakers are there. 

Super strange.  I don’t have an explanation, but I’m glad my system seems to be working now.

Hope this helps someone else.

Cheers.
