I've now managed to connect this to my play 1 but not my beam which it was bought primarily  to connect with

Which Sonos speaker is connected via ethernet?

Try unplugging your Beam from power for about a minute and reconnect the Sub.

I have connected the sub via Etherley as it was strugglingbwith the WiFi. Just unplugged beam so will try again now. Thanks

Unfortunately still the same issue even though it says it has connected to the Beam it doesn't make the "chime" that it makes when connecting to the Play 1

Can you connect the Beam with the ethernet cable instead?

I can but unfortunately I can't connect the sub to the WiFi so I'll try and arrange another cable so I can connect both via ethernet cable 

Thanks
