We live in a two story house. The Ring Chime is about 25 feet from the Doorbell. We had a little trouble so I moved it closer. Subsequent to buying the Ring Chime, we bought a Ring Chime Pro. Extending the Ring Chimes own wireless network fixed the problem. We now have one upstairs and one down stairs and life is good. Not a cheap solution but a perfect one.
