For the tp link wifi extender setup Without WPS , the most efficient way is to configure the range extender via the administration website. You can access the Web Administration by connecting the range extension to Ethernet. (Each range extension package includes an Ethernet cable.)
Before you begin, make sure your range extender is turned on and off during this process. After connecting, plug one end of the cable into the Ethernet port on your laptop or desktop computer and connect the other end of the Ethernet port to the range extender.
