Also called a Wi-Fi repeater or Wi-Fi booster. A Wi-Fi Extender is a device used to extend your home Wi-Fi coverage. These devices connect to your home Wi-Fi and amplify its signal, so you get better Wi-Fi coverage in dead spots and, in some cases, a more reliable Wi-Fi signal. It’s a smart idea to talk to your internet service provider before you invest in a Wi-Fi Extender.
