Hi @nantwichguy
Welcome to the Sonos Community!
It seems your Sonos system is having a bit of trouble remaining connected to your Google Mesh - it’s trying to steer them to a 5GHz connection because they have 5GHz radios, but some won’t do so as they reserve their 5GHz radios for direct links (like your surrounds to your Arc).
As the Google Mesh will not allow you to split the 2.4 and 5GHz bands, we’ll need to take another path towards connection.
Please connect any one Sonos device (not a Surround, Sub or Roam) to your Google Mesh (or to a network switch attached to Google) with an ethernet cable and wait for about 1 minute. Keep the device 1m away from your Google node and router.
This device will transmit a private WiFi just for other Sonos devices which each device will repeat, creating their own mesh. The Roam will not connect to this network (SonosNet), but it will happily connect to 5GHz WiFi.
When creating a large group, it’s best to put the ethernet-connected device in charge of the group (selected first).
With the minute over, please check Settings » System » About my System and check that all speakers apart from the Roam report WM:0. Reboot any that don’t.
If you’ve had to move a speaker to do this, I recommend you test long-term (a week or so) and if you’re then happy with the performance but need to move your speaker back again, you may want to add a Boost to your system.
I hope this helps.
Hi Corry
Thank you for your detailed repsonse. I’ve now returned the google mesh wifi and have currently replaced this with a split channel router (which allows a different network name per channel) - all my speakers are now connected solely to the 2.4ghz channel.
I’m happy to say everything is now working perfectly. Grouped speakers with the roam in remain grouped and play - even the following day.
I’m going to get another mesh network - however this time I’ll ensure that the channels can be split and named specifically.

Hi @nantwichguy
I’m glad you’ve found a fix!
I’m not sure that any of the popular mesh systems allow splitting the bands. Hopefully someone in the Community that owns one that does can prove me wrong?
The new netgear ones offer this plus another 5ghz channel forwireless backhaul - not too expensive so will probably go for this

Thanks again for your help
