Hi @user68116. Insufficient power could cause this issue, especially since it has happened each time after the troubleshooting steps you've performed. Try reviewing our Hardwiring Checklist [here](https://community.ring.com/t/hardwiring-checklist-video-doorbell-pro/37520) to make sure your Doorbell Pro is wired up correctly. Once you've verified that the wiring is done properly, and there is sufficient power going to the Doorbell, check that the [RSSI](https://support.ring.com/hc/en-gb/articles/217271526-Checking-Your-Ring-Device-s-Wifi-Signal-Strength) indicates a strong and stable wifi signal. If this issue persists after reviewing the information above, I'd recommend getting in touch with our support team to troubleshoot further. You can reach out to our support team at one of the numbers available [here](https://support.ring.com/hc/en-us/articles/360036196372-Contact-Us#callus).
