I have the doorbell 2 and several outside cameras connected. Right now, I have the comcast combo modem-router. I just purchased my own modem and seperate router and I will be installing them this weekend. I know that my ring devices will get messed up. What do I need to do to connect all the devices to the new router? DO I have to get up on a ladder to take each camera out and go through the setup or is there a better way to do it?
