How to do it
Standard captive portal checks cannot be fully disabled via normal menus without developer options or private DNS tools.
Menu names may differ by device and version.
What you lose
Captive portal login prompts on public Wi-Fi networks may not trigger automatically.
What is collected
Ip address, request timestamps, http response headers.
The checks exist to detect restricted local networks and launch captive-portal login pages when required.
