My ring doorbell 2 cannot connect everytime i change the battery. It started a couple of months ago. It will connect after a few hundred of retries and it will work until i change the battery again. This time i give up. I keep on getting the white flashing light on the left. i have ring cameras and alarm also and all working fine. I am not sure what is the problem. I had this i think for almost 5 yrs already.
any help would be appreciated. 
Hi @koolitz. Approximately how far from the router is the Doorbell? We usually recommend a distance of 25 feet or less, as it may be harder to establish and maintain a connection at farther distances. As for troubleshooting steps, Iād suggest performing a full reset by holding down the setup button for 20 seconds. After the reset is complete, walk through a new setup in the Ring app using the steps under Set Up a Device.
If you run into errors trying to complete the new setup, we have more troubleshooting steps here for setup failures. Should this issue persist after trying the above, please follow up with our support team for more in-depth assistance. If you are outside of the US, please visit here to see how to contact support.
