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 NetworkSo effectively I guess I have connected all devices in series ?Is this the correct way to do this . Both device shiwing as onlineAlso I have a signal strength of RSSI-53 on both, what does RSSI mean and is this a decent signal ?Thank You Brian
