A Wi-Fi access point is a device that allows wireless devices to connect to a wired network. It acts as a bridge between the wired network and the wireless devices, enabling them to communicate and access the internet. Access points are commonly used in homes, offices, and public spaces to provide internet connectivity. Typically, a Wi-Fi access point connects to a router via an Ethernet cable. Once connected, it broadcasts a wireless signal that devices like smartphones, laptops, and tablets can use to connect to the network. This setup helps expand the coverage area of the network, allowing more users to connect easily.
