Impossibly poor connection

Since getting my doorbell 2 it’s always shown a weak/poor connection. I moved the router, increased my internet speeds, and finally upgraded to a mesh system that has two nodes no more than 12’ away. Every other device has full power at the doorbell location which leads me to believe there’s an issue with the doorbell2 wifi transmitter. I’m trying to keep my house safe and it looking to go with other cameras or devices, this doesn’t leave me confident to go with Ring. As there’s no way to hardwire a connection to the doorbell what can be done?
