To gain WiFi access with a laptop, you are required to have a Wi-Fi network. To create a Wi-Fi network, you need a power source, a modem and a Wi-Fi router.
A power source provides power to your laptop and Wi-Fi router. The modem allows your home to connect to the Internet.
The wireless router transmits the Internet signal from the modem to your home wirelessly. It also allows multiple devices to connect to the Internet from a signal.
To create a Wi-Fi network, plug your router into the power source and plug the modem into the router.
Power on your laptop's Wi-Fi and search for a signal.
