Hi all, Designing a NAC for work and I am having trouble getting Samsung devices to recognize the user must sign in to a captive portal for network access. I have managed to find the URLs that other products use for captive portal detection (i.e. captive.apple.com for iOS, and most Androids use clients3.google.com/generate_204). In fact, every device I have tested (apple, motorola, older samsungs, lg, nexus) seems to present the user with a pop up stating they need to log in to the WiFi. Newer Samsung devices (confirmed on Galaxy Note S5 and Galaxy S7) are not presenting this pop up. I think Samsung has butchered the Standard that Google created and I am wondering what URL they use for Captive Portal Detection in their newer devices. Thanks!
