Use Strong Passwords

Choose a long, unique password with a mix of letters, numbers, and symbols. Avoid common words and personal details. Changing your password regularly helps prevent hackers from gaining unauthorised entry. Image Source: Meta-AI

Enable WPA3 Or WPA2 Encryption

Ensure your router uses WPA3 or at least WPA2 security protocols. These encrypt your Wi-Fi traffic, making it difficult for attackers to intercept and misuse sensitive information on your network. Image Source: Meta-AI

Change Default Router Credentials

Many routers come with generic usernames and passwords. Updating these to strong, unique credentials prevents hackers from exploiting common defaults to access your router settings. Image Source: Meta-AI

Keep Router Firmware Updated

Manufacturers release firmware updates to patch vulnerabilities. Regularly check for updates and install them to close security gaps that hackers could exploit to infiltrate your Wi-Fi network. Image Source: Meta-AI

Hide Your SSID

Disabling SSID broadcasting ensures your Wi-Fi network is not visible to casual users scanning for connections. While determined hackers may still find it, this adds a layer of protection. Image Source: Meta-AI

Use A Guest Network

Enable a separate guest Wi-Fi network for visitors. This prevents them from accessing your main devices and data, while still allowing internet use without compromising your network’s safety. Image Source: Meta-AI

Limit Connected Devices

Regularly review the devices linked to your Wi-Fi. Removing unknown or unused ones not only improves speed but also reduces security risks from unauthorised connections. Image Source: Meta-AI

Enable Network Firewalls

Most routers include built-in firewalls. Activating them blocks suspicious traffic and provides a strong first line of defence against potential cyber threats and intrusion attempts. Image Source: Meta-AI

Place Router Securely

Keep your router in a central part of your home to ensure signal strength but avoid placing it near windows. This reduces the risk of outsiders detecting and attempting to access your Wi-Fi. Image Source: Meta-AI

Monitor Network Activity

Use router management tools or apps to track connected devices and activity. Suspicious activity or unknown devices can signal unauthorised access, helping you respond quickly. Image Source: Meta-AI
