What wrong with Ring devices and the network?

I have 2 cams, 1 floodlight plus and another Wired doorbell.Doorbell is connected to the Pro chime network. Pro chime is 10 feet away from the router and has RSSI-50 (higher than expected) value and the connected doorbell which is nearly 12 feet away from chime has RSS - 61butFloodlight is connected to the home network which is less than a meter away from the router but still has RSSI-69 and when connected to Pro-chime which is 12 feet away gives RSSI-68The flood light usually has RSSI >66 and the connection frequently drops, I called the customer care to seek help, but they kept saying improve the home network or install a repeater. But the floodlight is immediately next to the router and the other devices in the house is working fine on the 1GBPS broadband and I am only facing issue with the floodlight.I tried moving the route around and standard ring troubleshooting steps and what not but unable to resolve the issue with the Ring Floodlight. Can anyone please help?
