Try rebooting your router and restarting your phone.

Tried that but it keeps happening, don’t think sonos likes Wi-fi 

Be sure your phone is on the same Wi-Fi network as the speakers.

Do you use a VPN connection?

Are you able to wire your Beam to your router with an ethernet cable?

The phone is connected to the same Wi-fi. The beam isn’t connected with  cable but I could use a cable to re set it if that’s what you mean?

I mean connecting your Beam to your router with an ethernet cable to see if that improves the Sonos app’s ability to connect to the speaker.

You could be experiencing Wi-Fi interference. Read this article for ways to reduce wireless interference: https://support.sonos.com/s/article/3286?language=en_US

Ok, will do. Anything to stop all the hassle
thanks for the advice
