Chime Pro setup - wi fi network - which one ?

As a newbie to Ring Products, I have recently purchased a Video Doorbell 3 Plus and a chime pro. I installed the 3 plus first but had trouble with a good wi fi connection so today bought and installed the chime pro. Not sure if I have set up the wi fi networks correctly so could someone tell me if this is correct. My Chime Pro is connected to my main home network. My Video Doorbell 3 PLus is connected to my Chime Pro Network So effectively I guess I have connected all devices in series ? Is this the correct way to do this . Both device shiwing as online Also I have a signal strength of RSSI-53 on both, what does RSSI mean and is this a decent signal ? Thank You Brian
