What Is Wi-Fi and How Does It Work?

Wi-Fi is a wireless networking technology that allows devices to connect to the internet and communicate with each other without physical cables. It uses radio waves to transmit data between your laptop and a router, which is connected to your internet service provider. Understanding the basics of how Wi-Fi works helps you better understand how to set wifi in laptop effectively.

When you set up Wi-Fi on your laptop, the laptop’s wireless adapter searches for available networks broadcast by nearby routers. Each network has a name, called an SSID (Service Set Identifier), and often a password for security. Once your laptop connects to the router, it can access the internet through the router’s connection.

Modern laptops come with built-in Wi-Fi adapters that support various standards like Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax). These standards determine the speed and range of your wireless connection. The router you connect to must also support the same or compatible standards for optimal performance.
