Changed my WiFi router password and now Ring 2 Doorbell will not work

Folks: I tried for several days to reset my Ring2 Doorbell after I changed my WiFi router password. Finally during the setup process I discovered that I needed to say NO when asked if I wanted to connect to the last WiFi network that I had previously connected to. Then I did see the same WiFi network and asked to join. Then I was able to enter the new WiFi router password and get connected. None of the video help topics helped and I didn't see this topic on this forum. I believe this is a common problem and should be included in the help video and the setup booklet. Thanks
