7 Tips to Secure Your Home Wi-Fi Network

Your router connects computers and other devices to the internet. These seven checks can help you understand its settings and reduce avoidable security risks at home.

1. Change default administration credentials

The router’s administration sign-in is separate from the password used to join Wi-Fi. Check whether default credentials are still in use and follow the manufacturer’s instructions for changing them. Keep the new details somewhere safe.

2. Review connected devices

Use the router’s app or administration page to review the devices on the network. Device names can be unfamiliar, so investigate before assuming an unknown label is an intruder. We can help identify equipment and review access.

3. Check remote management

Some routers allow management from outside the home network. Review whether that feature is needed and follow the provider’s guidance before changing it. ISP-managed and app-managed equipment may work differently.

4. Use appropriate Wi-Fi security

Choose a strong, unique Wi-Fi password and supported modern security settings such as WPA2 or WPA3. Check the router’s instructions and the requirements of older devices. Avoid leaving the main network open without a password.

5. Set up guest access thoughtfully

A guest network can give visitors internet access while separating them from your main devices, depending on its configuration. Check isolation and access options rather than rely on the network name alone. A separate network may also be useful for some smart devices.

6. Keep connected devices updated

Install supported security updates on computers and other equipment using the network. Review devices that no longer receive updates. Router settings alone cannot protect every account or device against every threat.

7. Update router firmware

Check whether the router installs updates automatically or needs attention through its official app. Follow the manufacturer or internet provider’s instructions. If the equipment is no longer supported, ask about sensible replacement options.
