When you attempt to configure the device, you discover that neither the router nor the extender is working. Simply take the router, plug it in to the power adapter, and turn it on using the socket. To use the internet, you need an Ethernet connection. So, simply look for the WPS button after connecting the Ethernet. This is an easy solution that only requires hard pushing the Wavlink extension after the router. When the ring light goes solid blue, it indicates that the extension and router are now unquestionably in excellent communication. The procedure fails if the device is up and showing a red light, or blinking red light in any way. For the wavlink router setup, blue light is a must.
