Office guest Wi-Fi captive portal loops forever

Minimal guidance for messy support realities.

Scenario

Visitors complete the captive portal prompt, but the splash page reappears on every new browser request.

Recommended Resolution Path

  1. Check controller session state, DNS interception, and HTTPS redirect behavior.
  2. Test whether device MAC randomization is confusing portal session tracking.
  3. Inspect certificate trust and browser privacy controls on modern mobile devices.
  4. If the issue affects only one SSID or AP group, compare policy bindings there first.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
