Android phones have no problem popping up the external captive portal page. However iPhones, when connected to the AP, do not trigger the captive portal.
If the user opens their browser and enters "neverssl.com" then the captive portal instantly pops up.
Using AP11s InstantOn with WiFi enhanced open running version 3.0.0.2
Is there a setting to force the captive portal? Blocking captive.apple.com before login would work, for instance, but where would that setting go?
