Abstract:
A method for detecting a captive portal on a Wi-Fi network in which a device generates a random private IP address and attempts a TCP connection on HTTP port 80 and HTTP port 8080. Upon an unsuccessful TCP connection a determination is made that no captive portal is associated with the Wi-Fi network and upon a successful TCP connection, a determination is made that a captive portal is associated with the Wi-Ft network.

Claim (Index 1):
A method for detecting a captive portal on a Wi-Fi network, the method carried out on a device having a processing unit including a non-transitory computer-readable storage medium capable of executing instructions of a software program, the method comprising the steps of:\n connecting to a Wi-Fi network; acquiring an Internet Protocol (IP) address from a dynamic host configuration protocol on the Wi-Fi network; setting the Wi-Fi network IP address as a default gateway to Internet; generating, at the device, a random private IP address; attempting a TCP connection to the random private IP address on HTTP port: 80, HTTP port: 8080, or HTTP port: 80 and HTTP port 8080; upon an unsuccessful TCP connection to the random private IP address, making a determination that a captive portal has not been detected; and upon a successful TCP connection to the random private IP address, making a determination that a captive portal has been detected.
