Perhaps see this earlier thread and comments from the Sonos Staff…

It’s clearly a known issue and Sonos Staff are investigating the matter.

Ok thanks, not sure it is the same issue but why not…

I checked my wifi frequency, and my sonos devices and my phone are using 2.4 mhz.

Thank you

Seeing all posts on this forum this is an extremely common problem since a couple of weeks. It’s quite incredible how Sonos has been succesful at completely destroying their brand. I’m giving up and moving to th Wiim Pro Plus, only $175 at amazon right now and unlike Sonos it actually works.

I don’t understand your answer regarding Win Pro Plus. Could you explain please ?

he’s just saying he’s giving up on sonos and buying whatever speaker that is

​@YohannB Well after getting extremely frustrated with Sonos I’ve been researching what alternatives there are for my Sonos Amp. If you do that you’ll soon find everybody is raving about the “Wiim Pro Plus”, it’s a new brand streamer which you can find it on Amazon. Google the reviews, check what the Hifi professionals on the internet say and you’ll soon see what I’m talking about. It seems to be a true Sonos killer at a fraction of the price. Just hoping I’m not going to run into similar problems.
