Boot loop on doorbell

I bought a ring doorbell around a week ago. I couldn’t get the wire connected in my old chime so decided to leave it out and use my Alexa and phone notifications to know when someone is at the door. It works well for a while but then the old chime sound keeps going off and the doorbell goes into boot loop. I can set it up again then it works fine until it happens again. I’m not sure if this is to do with my WiFi connection but don’t want to spend money on an extender if there’s another way to fix it
