Video Doorbell doesn't connect to Wifi Pod

I am using video doorbell pro 2. I've a Wifi pod in my house. The issue is the doorbell doesn't want to connect to the wifi pod, it prefer the gateway despite the poor signal, I've tried every thing like change the location of pod almost every where in the house, reset the doorbell and rest the modem still connect to the modem not the pod. Sometimes It connects to the pod then goes back to the gateway. When it connects to the pod gives RSSI-40 signal, but gateway provides RSSI-75 which makes it freeze. Any one can help?
