What is Wi-Fi and how does it work?

Wi-Fi is a wireless technology that allows you to connect devices without using wires. The history of Wi-Fi began in the late 1980s, when the US Federal Communications Administration began looking for ways to use the free radio frequency range to transmit data. In 1997, the Wi-Fi Alliance was created, which began developing standards for wireless communication. The first standard, 802.11, was released in 1997 and provided data transfer rates of up to 2 Mbps. Since then, several new standards have been released, such as 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac, which increased data transfer rates and expanded the frequency range. Wi-Fi became widespread in the 2000s, when the first laptops with built-in wireless adapters were released. Today, Wi-Fi is used everywhere, from free hotspots in cafes and airports to home networks and business networks. Wi-Fi continues to evolve, and today we see new standards emerging, such as Wi-Fi 6E, which allows for frequencies up to 6 GHz for even faster data transfer.

How to protect your Wi-Fi network from hackers and viruses

Wi-Fi networks are becoming increasingly popular and are widely used in homes and offices. But as the number of devices connected to Wi-Fi increases, so does the threat of hacker attacks and viruses. Here are some simple but effective ways to protect your Wi-Fi network.

1. Change the default password

Most routers come with a preset password that is easy to guess. Therefore, the first step to protecting your Wi-Fi network is to change the default password to a more complex one. Use a long password consisting of letters, numbers and special characters.

2. Enable encryption

Encryption makes data transmitted over Wi-Fi unintelligible to outsiders. The most common encryptions are WEP, WPA and WPA2. It is best to use WPA2 as it is considered the most secure.

3. Disable SSID Broadcast feature

The SSID is the identifier of your Wi-Fi network, which appears in the list of available networks. Disabling SSID Broadcast makes your network invisible to others. This is not 100% security, but it does make it difficult for those who don't know your network ID to access your network.

4. Turn on your firewall

A firewall protects your network from malware and attacks. Most routers have a built-in firewall, which can be enabled in the router settings.

5. Update your router

Router manufacturers regularly release updates that fix vulnerabilities and improve security. Therefore, it is important to check for updates and install them promptly.

By following these simple measures, you can protect your Wi-Fi network from hackers and viruses. But don't forget that security should be a constant concern and regularly scan your network for vulnerabilities.

What type of encryption to choose for Wi-Fi

Choosing the right type of encryption for Wi-Fi is a very important step to ensure the security of your wireless network. There are several types of encryption such as WEP, WPA and WPA2.

WEP is the oldest and least secure type of encryption. Hackers can easily break through it using special tools. Therefore, if you can, avoid using WEP.

WPA is a more secure type of encryption than WEP, but is still vulnerable to attacks. It uses stronger encryption methods and more complex passwords.

WPA2 is the most secure type of encryption and uses more complex encryption methods and longer passwords. If you have the option, use WPA2 to ensure the highest level of security for your wireless network.

It's also important to remember that even when using the most secure type of encryption, your network may still be vulnerable if your password is too simple or easy to guess. Therefore, use strong passwords and update them regularly.
