What is a Wi-Fi USB Dongle?
A Wi-Fi USB dongle, also known as a Wi-Fi adapter or Wi-Fi stick, is a small device that plugs into a computer’s USB port to provide wireless internet connectivity. It is essentially a portable Wi-Fi router that allows users to connect to the internet from anywhere, as long as there is a Wi-Fi network available. Wi-Fi USB dongles are commonly used with laptops, desktops, and other devices that do not have built-in Wi-Fi capabilities.
How Does a Wi-Fi USB Dongle Work?
A Wi-Fi USB dongle works by using radio waves to connect to a nearby Wi-Fi network. Here’s a step-by-step explanation of the process:
- The Wi-Fi USB dongle is plugged into a computer’s USB port.
- The dongle is powered by the computer’s USB port and begins to search for nearby Wi-Fi networks.
- Once a network is detected, the dongle sends a request to connect to the network.
- The network’s router authenticates the request and grants access to the network.
- The dongle establishes a connection to the network and begins to transmit data between the computer and the internet.
