How can one secure their wireless network against unauthorized access?

Securing your wireless network against unauthorized access is crucial to protect your personal information and ensure that only approved users can connect. Here are some key steps and tools to help you enhance the security of your home Wi-Fi:

1. Change Default Admin Credentials: Start by changing the default username and password for your router’s administration interface. Using a strong and unique password will prevent unauthorized access to your router settings.

2. Enable WPA2/WPA3 Security: Use the strongest encryption available on your router, which is currently WPA2 or WPA3. This will encrypt the data transmitted between your devices and router, making it harder for hackers to intercept.

3. Strong Network Password: Set a strong and unique Wi-Fi password. Avoid using easily guessable passwords like “password” or “123456”. Use a mix of letters, numbers, and special characters for better security.

4. SSID Broadcasting: Disable SSID broadcasting on your router. This will make your network invisible to devices scanning for available networks. You will need to manually enter your network information to connect, adding an extra layer of protection.

5. MAC Address Filtering: Configure your router to only allow specific devices to connect by filtering MAC addresses. This restricts access to only devices whose MAC addresses are whitelisted.

6. Network Segmentation: Consider setting up a guest network for visitors. This will isolate their devices from your main network, protecting your personal data.

7. Firmware Updates:
