To trigger a WIFI login page, open your device's WiFi settings and connect to the network. Once connected, open your web browser and try to load any webpage. If the network requires a login, the login page will automatically appear. Enter the required information, such as a username and password, or accept the terms of service. After submitting the necessary details, you will be connected to the internet. If the login page does not appear, try disconnecting and reconnecting to the network. You can also try clearing your browser cache or using a different browser. Remember to ensure that your device is connected to a compatible WIFI network and that you have the correct login information if required.
