sonos Beam wont connect to system

Try a temporary Ethernet connection to the Beam.

Please don’t factory reset, it obstruct us, and particularly Sonos in helping you.

Would be nice to know about your network, too. Make and model of your router, broadcast channel and frequencies, etc. 

Here is my router info for you 

So, what happens when you temporarily connect your Sonos to that router, as suggested by ​@Stanley_4 ?

Still won’t connect via Ethernet cable

Interesting. That suggests one of two things. Either it’s already been set up on a different LAN (which should have been cleared when you did a factory reset) or there is some issue with the Beam itself. I’d recommend that you call Sonos Support to discuss it.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks for your help, I’ll give them a call tomorrow
