What error messages are you seeing?

Since you’re setting the Ports up as a new system you’d need to reset or reinstall your Sonos app first. If there are any problems it may help to wire one of the Ports to the network and begin by configuring that one.

The Message is that there is a problem adding the Port to my system, I tried to wire it directly to the router and it still has the same problem.

What router is it? Is the WiFi a ‘guest’ network by any chance? Have you used Sonos successfully with that router before?

Yes, the Sonos ports were working on the previous account on the same router and switch

I’ve asked for a Sonos staff member to take a look.

When you factory reset the two Ports, were their status LED’s flashing green? Just checking you did actually get them back to their initial factory condition, ready to be setup on your new Sonos account and did you also reset the Sonos App for use with the new account credentials too?

Yes, I reset both App and Ports and the port were flashing green after reset

Hi @FarouqAshoush 

Welcome to the Sonos Community!

Just in case this is easy to resolve, please reboot everything involved: if the speakers are flashing green, they won’t need it, but please reboot your phone (or try another) and reboot your router by switching it off for at least 30 seconds.

Please also keep the ethernet connection for now, as it will increase your chances of success. If reboots do not resolve the problem, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.
