I'm upgrading to AT&T fiber tomorrow morning. They tell me this will require not only running fiber to the house, but replacing my existing wireless router (gateway). I plan to create the same networks I currently have, and use the same passwords.
I realize that killing my wi-fi for several hours will confuse my wireless devices (Rachio is one). Would it be better to just unplug the Rachio during the service window, then once everything is up and working, plug it back in? Since I'm using the same network name (SSID) as before, and the same password, I would expect the Rachio to power up and re-connect.
