Understanding Wi-Fi Connectivity
Before we dive into the troubleshooting process, it’s essential to understand how Wi-Fi connectivity works. Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. Wi-Fi networks use radio waves to transmit data between devices, and they operate on a specific frequency band, typically 2.4 gigahertz (GHz) or 5 GHz.
How Wi-Fi Networks Work
A Wi-Fi network consists of a wireless router, which is connected to a modem and a device, such as a computer or smartphone. The router broadcasts a unique identifier, known as an SSID (network name), which allows devices to detect and connect to the network. When a device connects to a Wi-Fi network, it sends a request to the router, which then authenticates the device and assigns it an IP address.
