Sorry to hear about this experience neighbors! It looks like you’ve all taken the proper steps to troubleshoot by checking wiring/ power and wifi connection. If you are receiving power, but the Pro is not connecting to wifi, I recommend holding the setup button for 20 seconds to reset it and then performing a new setup in the Ring app.
If your Doorbell pro is completely unresponsive after confirming there is power to it, please reach out to our support team, at 800-656-1918, as it may require more in-depth troubleshooting.
