When a user fails to access the tplinkwifi.net window of the Tp-link router, there may be several reasons behind it because of which the user is facing that issue. First, you need to check that you are even connected to the Tp-link router’s network or not. If a user is not connected to the Wi-fi network of the router, disconnect all the devices and reconnect them. The reason behind the tplinkwifi.net issue can also be that you are using the wrong browser to access the web interface of your router.
