sonos products dropping off wifi network

Sounds like network issues. I’m not surprised the Sub is staying connected, it is actually connected to the Era 300, and only receiving a proxy IP address from the router.

Try unplugging all Sonos devices from power. Then reboot your Google mesh router (and pucks, if there are any). Wait two minutes, then plug back in your Sonos devices. Wait another two minutes, they should all be showing in your controller, and you should be able to do any test you want.

Remember, Sonos has a network FAQ here, but if you run into any issues, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

You’ve received excellent advice thus far. Also it appears that with the Google Nest Wifi Pro all bands use a single SSID which is great. Using different SSID’s for WiFi bands is old school and can cause problems for Sonos.

I don’t know how long you have had your current network setup or even if Sonos was working fine until recently. However, Band Steering may be the cause of your issues with Sonos. My research shows that the feature cannot be deactivated. The information is somewhat contradictory in that in the last statement the system supposedly will allow devices to decide their connection point after an analysis. While Band steering works in normal environments Sonos does not play well under those conditions.

Hopefully, you’ll be able to resolve your issues and enjoy Sonos!

Thanks everyone great advice 

I have a 4 x device Google mesh and I think it a black spot where the Era 300 are positioned.
Era300 must be more sensitive than TV and PC.

I temporarily repositioned the primary Google device (as a test), running a cable back to router and have Era300 back online and working well. 

Think I’ll need to design an new Mesh device layout

My ISP does band steering.  I cannot change that.  I guess they do it very well as I have never had connection issues.  I’m not saying band steering can’t cause connection problems.  It just doesn’t happen here.

Maybe I have good connection reliability because I don’t have a mesh system.  I do have what my ISP calls a WiFi extender.  That seems to work well also.

At times I wish I could choose which band to use for which device, but at this time band steering works for me.

You can view the network status of your speakers under settings, both a general fair/good rating as well as the actual signal strength.

Really handy for finding dead spots, like the one next to my refrigerator that blocks a lot of signal. A couple foot move got my signal back.

In my last post I stated that Band Steering works very well for me.  For the most part this is true.  There is one case where I would favor being able to intervene.  The stereo pair of Move speakers are very far away from the ISP Gateway so they are forced to connect to the WiFi extender.  For some reason they are steered to the 5GHz band rather than the 2.4GHz band.  Because 5GHz does not penetrate walls as well as 2.4GHz does the Move pair show a “Fair” signal.  They work OK, but if I had my druthers I would prefer putting them on the 2.4GHz band.  Music streaming does not require a 5GHz connection.
