How WiFi Works?

WiFi works by emitting radio waves in various frequencies to provide a wireless internet connection. To capture the internet connection, you need a device that can manage the internet network such as a router.
When a device wants to connect to a WiFi network, it will send a request message that can scan for the nearest available network.
Then the request will be responded to by the router by sending a message containing the network name (SSID), encryption type (if any), and signal strength (RSSI).
Upon receiving a signal from the router, the device will be prompted to send an authentication request (such as a WiFi password). Next, the router will verify and assign it an IP address so that it can connect to the internet network.
