What is a Wi-Fi router and how does it work?
A Wi-Fi router is a device that connects to a modem and allows multiple devices to connect to the internet wirelessly. It works by receiving the internet signal from the modem and converting it into a wireless signal that can be detected by devices such as laptops, smartphones, and tablets. The router then transmits this signal to the devices, allowing them to access the internet.
