Does your question mean that you are using a router administration tool that shows you the connected clients of the router and there the Edimax gateway does not appear among the wired clients? That is the meaning of your question for me. If it is for you, then either the gateway is not receiving power from the power adapter, the gateway has a hardware defect or the Ethernet connection to the router is broken.

However, your question may mean that you assume that all you have to do is insert the batteries and plug the power adapter into the gateway and then the camera will somehow appear on your Wi-Fi network. However, this is not the case; the system is rather structured as follows: The camera unit, which is installed in the door, connects to the gateway, i.e. the white box with the antenna, via radio. This is connected directly (or indirectly via other network components) to the router via an Ethernet cable (but this connection is definitely not possible directly via WiFi). Now you can access the camera with a smartphone or computer in the same network, in each case with the help of the corresponding Edimax app installed on it. You can access the camera. On the computer, you can also access the gateway in a browser using the IP address of the gateway that the Edimax app. shows you in order to configure the settings (such as notifications when someone is at the door) according to your wishes.
