Increasing RSSI

Since getting my ring 2 doorbell I’ve been struggling to get an rssi above 50. I’ve moved routers, and even purchased new ones to test but nothing. I currently have a mesh system with nodes very close to the doorbell but, roughly 10-12’ away, and only at 44. It feels like nothing short of having it connected right to a router, which I don’t think you can, it won’t get better and live feeds will always be delayed or struggle to connect at all. If anyone has suggestions please let me know. Fk
