Sometimes, the IP address of the router automatically changes. The default IP address of the Tp-link router is 192.168.1.1 with which a user can access the web interface of the tplinkwifi.net window. If for some reason the IP address has changed or your network manager has changed it, you can assign a new IP address to the router using the web management window. Sometimes, a user fails to interact with the web interface of the router through the tplinkwifi.net link, he can also type 192.168.1.1 as an alternative to access its web interface.
