You can use the WPS connection method with the PIN method to create a safe and secure connection. With the help of the PIN method, you can keep unwanted users away from the network. A user who wants to connect to the extended network must know the PIN of the device with which they are trying to connect. You can create a PIN for your Wi-fi device using the Connect devices (WPS) page of the dlinkap.local interface.
