Google Home not find my devices in the same Wi-Fi

[Monteirok]

I set up my devices and now just shows it not connected in the same Wi-Fi, but all are in the same Wi-Fi, and I can't use all my devices into Google Home. Please any idea what's happening? Thanks

Hi Monteirok,
 

Thanks for posting — let's get this sorted out. A few questions: what are the devices you set up? Are you using a dual-band router? If yes, on which band did you connect these devices? 

Regards,
Alex
