Hi all,
Since upgrading to a 2.4/5ghz auto switching router we had issues with our system and not been able to connect to it at all - despite the devices all being visible on the network. The easy fix was to add a sonos boost to the system which fixed the issues with the two sonos ones used as rear surrounds. The amp however remains an issue, the app can find it but it simply doesn't add the device including when connecting via eirhernet. Sonos support have been no help at all with this issue so hopefully the community can provide a fix?
