Hey neighbors! When the Ring setup AP is not allowing a connection, this can be indicative of mobile device connection or power concerns. If you are trying to setup a Doorbell Pro, please ensure your transformer is rated for 16 - 24 VAC and the wiring is not too thin or corroded.
I recommend also disabling any bluetooth, hotspot, or VPN connections on your mobile device, as well as closing apps in the background. If this concern persists, reach out to our support team, at 800-656-1918, for more in-depth troubleshooting.
