Abstract

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

Description

technical field [0001] Inventive subject matter relates to a method for captive portal detection. Background technique [0002] Captive portals are provided by locations that offer free Wi-Fi hotspots to end users. A captive portal is a web page that end users are forced to visit and interact with before access to free Wi-Fi becomes available. Example locations may be, but are not limited to, a corporate office, an airport, a hotel, a coffee shop, etc. where a guest logs in. Captive portals enable network administrators to allow Internet access to authorized users. In a captive portal network, Wi-Fi authentication is always open authentication, and real user authorization is enforced through a web page where the end user interacts to enter login credentials. [0003] One of the most widely used implementation mechanisms is HTTP redirection. With HTTP redirection, a gateway on the AP network (or the AP itself with captive portal support) hijacks HTTP requests from connect...
