How to know the WIFI security protocols and change it?

You can check the Wi-Fi security protocol on your Android phone. iOS devices don't support checking the security protocol of connected Wi-Fi networks.

If you need to change the security protocol, please follow these steps:
1.Find the login website, username, and password on the sticker attached to the router body. The password might have been changed during router setup, so enter the actual one accordingly.

2.Open your browser on a device already connected to WiFi (such as your phone or computer), then enter the login URL.
Fill in your username and password to sign in.

3.After logging in, please locate and click into the wireless settings page.

4.Change the Security Mode to WPA or WPA2 on the Wireless Security page. It's recommended to set it to WPA2 for better security.

5.Save the settings and restart the router to apply the changes.

Note that the setup process may vary depending on the router model. We recommend consulting the router's user manual or reaching out to the router supplier for specific instructions.
