Sonos Speakers not pairing in Meraki WiFi

[EdgeFarming]

Hi, 

I have some sonos speakers connected to my provider's wifi-router throught WiFi and they use a kind of multicast to syncronize and they work well.

I have connected a Meraki switch to my provider's wifi-router and connected 2 MR-36 and 1 MR-28, now I connect the Sonos to an SSID from Meraki using Bridge configuration so they can talk to each other and also allowing to talk to each other in firewlall configuration, but that dont work well, they cannot talk well to each other and they dont syncronize.

Any thoughts?

Thanks

Personally, I'd just hook one of the Sonos' up via Ethernet and let SonosNet do it's thing. Otherwise there's a fair amount of discussion here: https://community.meraki.com/t5/Wireless/Connecting-Sonos-to-Meraki/m-p/83582

The first thing to check is whether you've set firewall of the SSID to allow local LAN traffic, as on the first SSID slot this is disabled by default.

Can you clarify what you mean with "cannot talk well ..."?

This setup is what I always use and prefer:

Yes, I don't like a parallel wireless infrastructure in my home, also if it is only on 2.4 GHz.

As already mentioned, no client Isolation and Firewall Rules allow access.

With this setup, none of the speakers should have its own wired connection, when using the Sonos own WLAN network, only one speker should have a wired connection.

Jep, Sonos is networkwise quite garbage and can even cause network instability because even when they connect with Wi-Fi they sometimes also forward over their wireless backhaul and that behavior can be different per firmware version!

Most of my customers connect them wired and we haven't had any issues of them communicating to each other.

I believe they use 239.255.255.250 which is the uPnP address to talk to each other.  Make sure you have multicast to unicast conversion set to on in your network (general settings) or else that will cause pains with lost multicast frames.

Hi GIdenJoe, 

I have not tested disabling tha multicast to unicast conversion, maybe that's the problem, I will give it a try.

Sonos is not designed to work with commercial networking equipment. It is a consumer device meant for home users or at best SMB/SOHO.

Hi, If it works on comercial simple wifi it should work on Meraki as well I thing so. Not using any special protocol.

Make sure the SSID does not have "Deny Local LAN" enabled.

Hi Philip, 

Yes, It's allow since the begining:

Agree with outers here, if it can be wired WIRE it up. Your first clue that any vendors STA devices are trash and an afterthought is it uses 2.4gHz only...

Hi, 

Sonos works fine wirelessly in my provider's wifi router, it should work on meraki as well for sure. In my case they all are totally wireless.  I thinking there's an issue with Multicasting.

[ConnorL]

Have you reviewed any of the suggestions provided? The firewall on SSID 1 default config is usually a trip hazard.

Hi, 

Set ok since the beginning:

Thanks
