Poor Chime network

I have just installed my Chime pro, as the doorbell has poor WiFi connection. Now the Chime is Connected with task -43 But the doorbell just got to -63. The distance between the 2 devices is just the wall, nothing else. It seems that the Chime has a real poor antenna build in. I have only issues with my doorbell. I bought the Chime also because my Alexa is stop working after 2 rings. No live view seen on Alexa. So for me all those systems seems not really we’ll developed
