If you fail to connect the extender to the router by pushing the WPS button, then don’t worry you can also connect that gadget with the help of an ethernet cable. This method is not so complicated or technical.
First, put the power plug of the Wavlink extender in a wall socket. Now, take the WiFi gadget and connect it to the extender network by using an ethernet cable. Now, open Chrome on the WiFi-containing gadget and enter the wifi.wavlink.com web portal in the URL bar. After that, a login page will open up on your display. Later, fill in all the login details such as username and password. For further login, click on the setup wizard option. Now, from the WiFi list select your own WiFi network and fill in the password. In the end, wait for a while to see the Extender successfully linked notification on your display.
With the guidance of this page, the Wavlink extender setup process is successfully done.
