So, what do you do when your Wi-Fi connection suddenly vanishes into thin air?
Understanding Wi-Fi Connections
Before we dive into the troubleshooting process, it’s essential to understand how Wi-Fi connections work. Wi-Fi is a 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 GHz or 5 GHz.
How Wi-Fi Connections Are Established
When you try to connect to a Wi-Fi network, your device (such as a laptop, smartphone, or tablet) sends a request to the Wi-Fi router. The router, which is connected to a physical internet source (such as a cable or fiber optic connection), receives your request and authenticates your device using a unique identifier called an SSID (Network Name) and a password.
Once authenticated, the router assigns an IP address to your device, allowing it to access the internet and communicate with other devices on the network. The entire process happens in a matter of seconds, and you’re usually none the wiser.
