Cannot get Ring Bridge attached to ring system

Hi, I have a ring system with doorbell, two other cameras, and alarm system. I am using TP-link Deco mesh router With one of my android phones, I never got past the "blue light is flashing". With another android phone and attached to one of the satelite routers, I can get it to ask about wifi password, but it did not finish registering. I moved the bridge next to the main router and was able to get it "attached", but then it said it was updating itself and then said it failed. I had no problems getting any of the other ring devices attached (using the first android phone that did not work at all).
