Step by step

1. 2 min

   Update router firmware

   Log in to your router’s administrative interface through a web browser using the default gateway IP address. Navigate to the System or Maintenance tab and select Firmware Update to ensure you are running the latest security patches provided by the manufacturer.

   Note: Enable 'Automatic Updates' if the option is available.

   Enable WPA3 encryption

   Access your Wireless Settings menu and locate the security protocol selection. Change the encryption standard from WPA2 to WPA3-Personal to utilize superior password-based authentication and forward secrecy for your connected devices.

   Note: Some legacy smart home devices may require WPA2/WPA3 transition mode.

   Create a dedicated IoT network

   Navigate to the Guest Network or VLAN settings in your router interface. Create a secondary Wi-Fi network specifically for your smart home devices to keep them isolated from your primary devices containing sensitive data like laptops and smartphones.

   Note: Ensure 'AP Isolation' is enabled for this network to prevent inter-device communication.

   Disable remote administration

   In your router's Advanced settings, locate Remote Management or Web Access from WAN. Disable this feature to ensure your router settings cannot be accessed from outside your local network.

   Note: Only enable this if absolutely necessary for remote support.

   Disable WPS

   Locate the Wi-Fi Protected Setup (WPS) toggle within your router's wireless security menu. Disable WPS immediately to eliminate the vulnerability that allows attackers to bypass password authentication via brute-force PIN attacks.

   Note: Always pair new devices using the manufacturer's mobile application instead of WPS.
