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 the connection is established through a process called authentication.
How Wi-Fi Networks are Detected
When you turn on your PC’s Wi-Fi adapter, it begins to scan for available networks in the area. The adapter uses a process called scanning to detect the presence of nearby Wi-Fi networks. During this process, the adapter sends out a probe request to nearby access points (APs), which are devices that provide Wi-Fi connectivity. The APs respond to the probe request with their network name (SSID), channel number, and other relevant information. Your PC’s Wi-Fi adapter then uses this information to display a list of available networks.
