Can you please define what you mean by ‘reset’, as it has multiple potential meanings?
Have you rebooted your router? Have you wired one device to your router with an Ethernet cable? Which Sonos devices are we talking about? Which router?
Have you called Sonos Support directly to discuss it?
When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
