How Wi-Fi Works – Understand the Process

If you have ever wondered about How does Wi-Fi work? and since it is possible to connect to the internet wirelessly, know that this technology operates through data transmission without the need for physical cables or wires.

THE Wi-Fi, whose abbreviation comes from Wireless Fidelity, is a technology that is based on transmission of signals through radio waves.

Those signals are emitted by routers and subsequently received by compatible devices, such as smartphones, Smart TVs, computers and tablets.

What types of Wi-Fi networks are there?

There are a variety of Wi-Fi standards available, the most popular being 802.11n, 802.11ac and the most recent, 802.11ax.

Each pattern presents different connection speeds and range, with 802.11ax currently being the most advanced, ensuring a more agile and stable experience.

Additionally, the connection can happen through radio waves, cables and telephone lines.

How does Wi-Fi connect to the internet?

THE Wi-Fi connects to the internet using a router. This device is responsible for receiving the internet signal from the operator and distributing it to the devices connected to the network.

To perform this task, the router converts the data into radio signals and, through the Wi-Fi antennas, transmits the data to compatible devices, i.e. your cell phone, your Smart TV, among others.

How to set up a Wi-Fi router?

Although setting up a router may seem complex, it is a very simple process.

In general, you just need to follow a few basic steps, such as:

• Connect the router to the power outlet and the internet modem;
• Access the router configuration interface by typing the IP address in the browser address bar;
• Follow the manufacturer's instructions to configure the network name (SSID) and access password;
• Customize security settings, including encryption type and access control;
• Restart the router for the new settings to take effect.

How to connect to a Wi-Fi network?

Once you've set up your router, connecting to your Wi-Fi network is an equally simple procedure.

Just follow these steps:

• Access the Wi-Fi settings on the device you want to connect;
• Select the name of the desired Wi-Fi network from the list of available networks;
• Enter the access password, if it is a private network, and wait while the device connects.

And that's it! You are now connected and can use the internet without any problems.

Wifi Network Security Tips

Here are some tips on how to ensure the security of your Wi-Fi against potential intruders:

• Change your router's default password to a stronger password, making it more difficult for unauthorized access.
• Consider hiding your Wi-Fi network name (SSID). This can make it harder for unauthorized people to find your network;
• Keep a regular check on the devices connected to your Wi-Fi network and remove any unknown or unauthorized devices to ensure the integrity of your network.

Conclusion

After meeting How does Wi-Fi work?, be sure to take advantage of this amazing technology and connect to the internet anywhere, without having to rely on cables.

A benefit so integrated into our daily routine that it is difficult to give up, as it is a means of communication that makes our daily lives much easier.
