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 uses radio waves to transmit data between devices, and it operates on a specific frequency band.
Wi-Fi Network Components
A Wi-Fi network consists of several components, including:
A router, which is the device that connects to the internet and broadcasts the Wi-Fi signal
A modem, which is the device that connects to the internet service provider (ISP)
A laptop or device, which is the device that connects to the Wi-Fi network
A wireless network adapter, which is the hardware component that allows the laptop to connect to the Wi-Fi network
Wi-Fi Network Protocols
Wi-Fi networks use various protocols to manage data transmission and ensure secure connections. Some of the common Wi-Fi network protocols include:
WEP (Wired Equivalent Privacy)
WPA (Wi-Fi Protected Access)
WPA2 (Wi-Fi Protected Access 2)
WPA3 (Wi-Fi Protected Access 3)
