Door bell not working at all

I've just installed my ring door bell.To get a good Wifi connection I've connected it to a guest Wifi on a Wifi extender and it's all connected fine with an RSSI-43When I press the door bell button nothing happens. I get no notification. no ring nothing, on mobile or at the door bell. the bell is fully powered and from the app it's all reporting as good. on the app I can't view the video feed it just times out. connection wise. Doorbell --\> BT Wifi home hub powerline extender (on guest wifi) --\> Fritzbox router --\> internet possible routing issue ? or bad device ?Any help would be great as it's getting really frustating From the app I can't get any To note : I'm running the door bell off it's internal battery.
