A Guide to Setting Up a Secure Home Network

With the rise in remote work and online activities, having a secure home network is more important than ever. Not only does it protect your private information, but it also keeps your devices running smoothly. If you’re a non-tech person, worry not, because we’ve created an easy, step-by-step guide to help you set up a secure home network.


Step 1: Purchase a Reliable Router

The first step to a secure home network is investing in a reliable router. Look for a router that supports WPA3, the latest Wi-Fi security protocol. Check online reviews or ask for recommendations at your local electronics store.

Step 2: Update Your Router’s Firmware

Before you start using your new router, make sure it’s running the latest firmware. This software controls your router’s security features and should be updated regularly to protect against vulnerabilities.

Here’s how to do it:

1. Connect your computer to the router using an ethernet cable.
2. Open a web browser and enter the IP address for your router. This is usually printed in the router’s manual.
3. Login to your router’s settings. If it’s your first time, the username and password are often ‘admin’.
4. Look for an option that says ‘Update Firmware’ or ‘Router Update’. Click on it and follow the instructions.

Step 3: Change Your Router’s Default Login Credentials

Using the default login credentials can make your router easy to hack. Here’s how to change them:

1. While still logged into your router’s settings, find the ‘Change Password’ option. It’s usually under ‘Security Settings’.
2. Change both the username and password. Make sure to choose a strong, unique password that combines numbers, letters, and symbols.

Step 4: Set Up Wi-Fi with WPA3 Encryption

Now, let’s set up your Wi-Fi network:

1. In the router settings, go to ‘Wireless Settings’ or similar.
2. Create a unique name for your network, also known as the SSID.
3. Choose ‘WPA3’ as the security or encryption type. If WPA3 is not available, choose ‘WPA2’.
4. Create a strong password for your Wi-Fi network.

Step 5: Enable Network Firewall

Most routers have a built-in firewall that adds an extra layer of security:

1. In your router settings, find the ‘Firewall’ or ‘Security’ section.
2. Make sure the firewall is set to ‘Enabled’.

Step 6: Disable Remote Management

Remote management allows you to access your router’s settings from anywhere. While this can be convenient, it can also be a security risk:

1. In your router settings, find the ‘Remote Management’ or ‘Remote Administration’ section.
2. Ensure this setting is ‘Disabled’ or ‘Off’.

Step 7: Set Up a Guest Network

If you often have guests who use your Wi-Fi, setting up a guest network can help protect your main network:

1. In your router settings, look for ‘Guest Network’ or similar.
2. Follow the instructions to set up a separate network for guests. Make sure to use a different password from your main network.

Step 8: Keep Your Devices Updated

The last step is to ensure all devices connected to your network are updated with the latest software. This includes computers, smartphones, smart TVs, and IoT devices. These updates often include security patches that protect against new threats.

Step 9: Use a Virtual Private Network (VPN)

A VPN encrypts all your online activity, making it harder for hackers to intercept your data. Here’s how to use one:

  1. Choose a VPN service. Some popular options include ExpressVPN, NordVPN, and CyberGhost.
  2. Download and install the VPN software on all your devices.
  3. Log in and connect to a VPN server. You’re now browsing more securely!

Step 10: Disable Wi-Fi Protected Setup (WPS)

WPS makes it easy to connect new devices to your network, but it can also be a security risk:

  1. In your router settings, find the ‘Wi-Fi Protected Setup’ or ‘WPS’ section.
  2. Ensure this setting is ‘Disabled’ or ‘Off’.

Step 11: Turn Off UPnP

UPnP or Universal Plug and Play can be exploited by malware to attack your network:

  1. In your router settings, find the ‘UPnP’ section.
  2. Make sure to switch it ‘Off’.

Step 12: Regularly Check Your Devices

Make sure to periodically check all devices connected to your network. Look out for any unfamiliar or suspicious devices. If you find any, remove them immediately.

Step 13: Limit Wi-Fi Range

If your Wi-Fi signal reaches beyond your home, others might attempt to connect to it. To prevent this, try reducing your Wi-Fi range. You can usually do this in your router settings. Alternatively, you can place your router in the center of your home, so the signal does not reach too far beyond your walls.

Step 14: Use Network Security Tools

There are numerous network security tools available that can further enhance your network’s security. These include antivirus software, intrusion detection systems (IDS), and network scanners.


Setting up a secure home network might seem like a daunting task, especially for non-tech people. However, with this easy-to-follow guide, you can protect your network from potential cyber threats. Remember, cybersecurity is an ongoing process, so make sure to regularly update your router and connected devices. Happy surfing!
