To check whether the hotspot is working correctly, disconnect the wire that connects the PC/notebook to the router and connect it via WI-FI to the "Default location" network". Here too, check whether the PC/notebook wireless network card is set to DHCP (IP automatically assigned).
At this point, open any web page on your browser. You will automatically be redirected to the Captive Portal login page if the router was correctly set.
To complete the test, create a registered user (or prepaid ticket) in the application homepage, and enter the newly created user name and password.
