2. How it Works

Because there are many different possible setups for Wi-Fi networks, it can be difficult to understand exactly how they work. In their most basic form, Wi-Fi networks require a network provider such as an internet service provider (ISP) that provides access to the internet. Information from the internet travels through a standard wired network to a router. The router then codes the signal and uses radio signals to send it to Wi-Fi compatible devices. Because internet connections use two-way traffic, the router is simultaneously receiving and decoding information from the connected device. It then sends that information back through the wired connection.
