HINT Control is an open-source app that allows users to access advanced information and manage hidden settings of their home internet gateway. The app supports various platforms, including Android, and currently supports the Arcadyan KVD21, Sagemcom Fast 5688W, and Nokia 5G21 gateways.

The app provides a comprehensive gateway management system with advanced features that are not available in the default gateway settings. With HINT Control, you can monitor and control various settings, including Wi-Fi and other hidden settings.

However, it's essential to note that disabling the 2.4GHz and 5GHz radios in the "Wi-Fi" section may lead to Wi-Fi disconnection if you don't have a wired connection to your gateway. If you're looking for an app that provides advanced gateway management features, HINT Control is the perfect fit for you.
