The biggest difference between your wired internet connection and wireless internet connection is the cable. A cable connection uses a router or network card (usually built on your computer) and a cable that connects your computer to the router. On the contrary, wireless internet does not have much difficulty. The only component you need is your computer and router. How does wireless internet work? Well, your Wi-Fi provider will have a tower around it designed to receive radio signals from service providers. The antenna on your computer receives signals from the tower. So when your computer successfully receives radio signals sent from the nearest tower, you are connected to the Internet.
