Same problem here with brand new devices. :(

Does anybody known the solution about this problem?

Same here. I have spend 8 hours to try Connect new device. frustrating, the system does not detect WiFi, then it does not detect the device, it disconnects, when I detect it it is not visible in the system, finally it tells me to log in as the owner of the system. I bought the device new and unpacked it myself. very weak, I regret the purchase, I wasted my time and energy on something that should have worked after 5 minutes. completely disappointed

Anyone found a solution?? This is really frustrating tons of money on the products and can’t be able to use!!!!! 

Return your speakers, Sonos don’t want you to set them up.

And you are?
