Wired ring doorbell intermittently enters bootup loop

Hi @user7214. Which model of Ring Doorbell do you have? You can find which model you have by looking at the original packaging, at the back of the device, or on the Device Health page in the Ring App. Also, what is the RSSI on the Device Health page? The RSSI is a measure of the wifi connection that your Doorbell is receiving, which you can read more about here.
