I cannot find my Sonos after a new router install

I am about to lose it…

I updated my whole network with new router and switches.
The name (and password) of the wifi is the same.
I have 3 Sonos One (Gen2) and 1 Port.

I tried to reconnect my Sonos to my new network but without any luck.
I tried to update the network, no luck.
I tried to factory reset all my Sonos, without luck.
I tried to plug 2 of the Sonos One by ethernet, no luck.

I can go through the whole setup process for my Sonos but when I am done, the app see nothing.

“Your system not found on wifi”

Sometimes, I got the message:

“Your Sonos One has been added, but may not appear in your system. If so, unplug the powercord and plug it back in to finish the setup from System Settings”.
Not quite what it means because I cannot find this “System Settings” unless starting the whole process again…. without luck!

What am I missing here?

Amongst other things above, you say “I tried to factory reset all my Sonos, without luck.” Do you mean you couldn’t factory reset the speakers? 
 

If you have factory reset them, do so again to be sure you start from a stable point. Unplug them all, then factory rest just one of them to start. Then try installing just that one following the instructions for a new system. 
 

Then post again with the results of just that first speaker.

There’s a FAQ here that covers most of your questions, here. My suspicion is your new network doesn’t meet the requirements as suggested here. But I’d likely 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.

    ​@Airgetlam 
    I went through the FAQ and follow the different steps. But you gave me the idea to try to create a new test wifi.

    ​@nik9669a Yes, I did the factory reset again, with a new test wifi and it worked!

    Now, I need to “migrate” from my test wifi to my regular one.
    Any advice to not go into another loop?

    Thank to both of you.

        If there are issues moving back check the settings on the two wifi connections to see if the original has something that is upsetting g Sonos.
