Log In to the Web Interface:

Connect your laptop to the router via a wired or WiFi connection and enter the router URL (e.g., http://www.asusrouter.com) in your web browser.
Key in your router’s default username and password to log in[1][3].

Change Username and Password:

Navigate to the settings section and change the admin username and password.
Ensure the new password is strong and unique.

Enabling Firewall and DoS Protection

The firewall is a critical component of network security.

Enable Firewall:

Go to the Firewall section in the web interface.
Enable the firewall and set up general settings to filter packets. This will protect all devices connected behind your ASUS router from hackers[3].

Enable DoS Protection:

Turn on DoS (Denial of Service) protection to filter suspicious or unreasonable packets, preventing your device from being flooded with packets.
Set up rules to filter specific websites or network services based on your requirements.

Segmenting Your Network

Segmenting your network is essential for isolating IoT devices from your main network.

Using Guest Networks for IoT Devices

Guest networks are designed to provide a separate and isolated network for visitors and IoT devices.

Set Up a Guest Network:

Navigate to the Settings > Network > Guest Network section.
Enable the guest network and set a unique WiFi name and password.
This will ensure that your IoT devices are isolated from your main network, reducing the risk of a breach spreading[2].

IoT-Specific Settings:

Use the IoT guest network feature, which sets up a 2.4 GHz guest network with the most compatible settings for IoT devices.
This can improve connectivity and reduce issues with smart devices connecting to your network[2].

Managing WiFi Bands and Smart Connect

Managing WiFi bands and using Smart Connect can enhance both performance and security.

Enabling Smart Connect

Smart Connect allows all WiFi bands to use the same WiFi name and password, making it easier for devices to connect to the most suitable band automatically.

Enable Smart Connect:

Go to Settings > Network > Main network profile.
Select all WiFi bands and apply the settings. This ensures that all bands use the same WiFi name and password, simplifying device connections[1].

Disabling Smart Connect for Specific Devices:

If you need to isolate certain devices, you can disable Smart Connect and set different WiFi names and passwords for different bands.
This can be useful for devices that require specific band settings or for enhancing security by isolating sensitive devices[1].

Keeping Your Firmware Up-to-Date

Regular firmware updates are crucial for maintaining network security.

Checking for Firmware Updates

ASUS regularly releases firmware updates to patch security vulnerabilities and improve performance.

Check for Updates:

Log in to the web interface and navigate to the Firmware Update section.
Check if there are any new firmware updates available and follow the instructions to update your router[4].

Automatic Updates:

Some ASUS routers support automatic firmware updates. Ensure this feature is enabled to keep your router updated without manual intervention.
However, be aware that some users have reported issues with the auto-update system, so it’s good to periodically check manually[4].

Using VPN and AiProtection Pro

Utilizing VPN and AiProtection Pro can add an extra layer of security to your network.

Setting Up VPN

VPN (Virtual Private Network) can encrypt your internet traffic, making it more secure.

Enable Instant Guard:

Use the one-tap sharable VPN feature, Instant Guard, for encrypted connections when you’re away from home.
This feature requires a public WAN IP address and can be managed through the ASUS app[5].

Multiple VPN Connections:

The ASUS RT-AX88U allows you to connect to multiple encrypted VPN tunnels simultaneously.
This is useful for different devices or users who need separate VPN connections[5].

Activating AiProtection Pro

AiProtection Pro is a powerful security feature that protects your devices from various threats.

Enable AiProtection Pro:

Navigate to the AiProtection Pro section in the web interface.
Enable the feature and set up automatic updates to ensure your network is always protected from the latest threats[5].

Monitoring and Alerts:

Use the feature to monitor your network and receive instant alerts for new device connections.
This helps in identifying and blocking unknown devices, enhancing your network security[5].

Practical Tips and Examples

Here are some practical tips and examples to help you secure your IoT network:

Isolating IoT Devices

Example: If you have smart lights, thermostats, and security cameras, isolate them on the guest network to prevent any potential breaches from affecting your main network.
Tip: Regularly update the firmware of your IoT devices as well, as outdated firmware can be a vulnerability.

Using Strong Passwords

Tip: Use strong, unique passwords for all your devices and networks. Avoid using the same password across multiple devices.
Example: Use a password manager to generate and store complex passwords.

Monitoring Network Activity

Tip: Regularly monitor your network activity to detect any unusual behavior.
Example: Use the ASUS app to receive notifications about new device connections and group devices into user profiles for better control.
