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 8):
A computer readable medium comprising a program, which, when executed by one or more processors, performs an operation comprising:\n connecting a device to a Wi-Fi network; acquiring, at the device, 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 in a routing table at the device; generating, at the device, a random private IP address; attempting a TCP connection from the device 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, making a determination that no captive portal is associated with the Wi-Fi network; and upon a successful TCP connection, making a determination that a captive portal is associated with the Wi-Fi network.
