What is WiFi encryption and why is it important?
WiFi encryption is the process of encoding the data transmitted over your WiFi network to prevent unauthorized access. It is crucial because it safeguards your personal information, financial data, and online activities from being intercepted by neighbors or hackers.
When you encrypt your WiFi, even if someone gains access to your network, they won’t be able to read or exploit the data. WiFi encryption comes in different forms, including WEP, WPA, and WPA2. The most secure option is WPA2, which uses Advanced Encryption Standard (AES) with a minimum key size of 128 bits. Always choose WPA2 with AES encryption to ensure maximum protection.
How do I change my WiFi network name (SSID) and password?
To change your WiFi network name (SSID) and password, follow these steps: Log in to your router’s administrative panel by typing its IP address in a web browser. The default IP address is usually 192.168.0.1 or 192.168.1.1. Once logged in, navigate to the Wireless Settings section and look for the SSID and password fields. Replace the default values with your chosen network name and password. Make sure to choose a strong and unique password.
Remember to save your changes and restart your router to apply the new settings. It’s recommended to change your WiFi password regularly to maintain optimal security. Also, avoid using easily guessable passwords, such as your name, birthdate, or common words.
What is MAC filtering and how does it work?
Media Access Control (MAC) filtering is a security feature that allows you to control which devices can connect to your WiFi network.
