Just follow the instructions on the app and press the AOSS button on the AirStation. After that, it will configure all the security settings automatically.
Note:
This tool is not designed for use with other tools that provide an internet connection, such as the Android Browser. In addition, if your device supports Wi-Fi calling, you must turn it off during the AOSS setup.
