If you can easily run an Ethernet cable to your Beam, give it a try and see if it solves the issue. 
 

You might also try setting fixed ip addresses for your devices. 

Thanks for the reply I can’t get an Ethernet to the beam but I can to one of my many SL speakers and if I’m honest i would have no idea how to set a fixed it address 

So I use eero mesh and I can assign each speaker a fixed ip address would this help solve the issue 

Static/reserved IP addresses followed by a full Sonos and network reboot does solve a lot of hard to debug issues.

It may or may not solve yours but as it is a quick and easy thing to do and eliminates it as an issue I’d sure doing it before anything else. I did years ago and it fixed my glitches.

Forgot to mention: Don’t try using Ethernet to a Surround or Sub, that isn’t a good option, stick to primary speakers.
