Video doorbell won't connect to video on any device

I have a mesh wifi system that we can pick up 2 houses away. Our doorbell is right outside the room with the router. It takes 5-6 tries to get the doorbell to connect to video. It also is no longer connecting to the video on my echo show. It tells me someone is at the door but the video is frozen. This has gotten extremely frustrating because what is the use of having the doorbell if I can't see who is at the door. I still need to look out the window because I can't get it to come up on my iphone. I started using rapid ring which was a little better but now that doesn't want to open either.First try I get Wifi maybe blocking, second try connection too weak, third try connection lost make sure phone & device online, fourth try connection too weak, fifth try connection weak, sixth try make sure phone and device online, seventh try finally connects.FYI my RSSI is 56
