IMPORTANT: For this guide, we used an Android smartphone. However, the steps involved are the same on iPhones too. If you don’t know whether your ASUS router works with Instant Guard, go to the bottom of this page and check the list of supported models. Also, the Instant Guard app takes its router settings from the ASUS Router app. Make sure that the ASUS Router app is installed first and configured to work with your specific ASUS router.

How to install and set up ASUS Instant Guard on your smartphone

Instant Guard is a mobile app available for free to ASUS router owners. The app works both on Android smartphones and on iPhones. To set it up and use it, make sure that you are connected to the Wi-Fi broadcast by your ASUS router and install the app from the Google Play Store or Apple’s App Store.

The Instant Guard app automatically detects your ASUS router and mentions the model name. As you can see, we used an ASUS TUF-AX5400 to make this tutorial. Tap the shield in the middle of the app’s screen.
