Just like the web interface of a Tp-link router, extenders of Tp-link are also controlled and managed through its management window. A user can interact with the web interface of the Tp-link extender by typing tplinkrepeater.net as the web address of your browser. In case you encounter any kind of error, you also can type the LAN IP address of your Tp-link Extender. The LAN IP address of the Tp-link extender is 192.168.1.254. It is also necessary for a user to know the login password of the Tp-link Extender login window to reach the tplinkrepeater.net window.
