The Smart Doorbell must be connected to an single access point. If you are using a mesh network, please connect the camera to the nearest access point. To do this, the smartphone should be connected to the same mesh point. When you get to the Wi-Fi setup, the same network appears multiple times, in order of strength. You need to select your network at the top of the list as this is the access point your camera is connected to. If you are not sure you can plug out the other mesh cubes for 1 min to be sure to connect to the nearest.
