Deny Unknown MAC Addresses: Ensure that the router is set to deny access to all devices not on the list.
Save Changes: Save the settings for MAC Filtering.
Method 3: Disable SSID Broadcast
Disabling the SSID (Service Set Identifier) broadcast makes your network invisible to most users.
Access Router Settings: Log in to your router’s admin panel.
Locate SSID Settings: Find the settings related to SSID under Wireless Settings.
Disable SSID Broadcast: Uncheck the option that says “Enable SSID Broadcast” or similar.
Save Settings: Save the changes made. You’ll need to inform legitimate users of your Wi-Fi name and password since it will no longer appear in available networks.
Method 4: Set Up a Guest Network
If you frequently have guests who need to use your Wi-Fi but you don’t want to share your main network, consider setting up a guest network:
Access Router Settings: Log in to your router.
Set Up Guest Network: Locate the Guest Network option, usually in the wireless settings.
Configure the Network: Set a separate SSID and password for guests. Make sure to restrict access to your primary network and devices.
Enable Settings: Ensure your network is secured and save the settings.
Advantages of a Guest Network
- The main advantage is increased security by isolating your main devices from guests.
- You can set bandwidth limits for the guest network to ensure your primary network’s performance isn’t affected.
Regularly Monitoring Your Network
To ensure your Wi-Fi remains secure, regularly monitor the devices connected to your network. Make it a routine practice to check the connected devices section in your router settings at least once a month.
Update Router Firmware Regularly
Updating your router’s firmware is crucial for security. Firmware updates often include security patches that protect against emerging threats. To update:
Log in to your router settings.
Look for the Firmware Update section.
Follow the instructions to update your firmware if a newer version is available.
Utilizing Security Protocols
Ensure that you are using the highest level of security available for your network. WPA3 is the latest Wi-Fi security protocol and offers enhanced security features over its predecessors.
Conclusion
Blocking unauthorized users from your Wi-Fi network is crucial for maintaining the integrity and performance of your internet connection.
