A device that connects your home network to the internet is typically a router. Routers serve as a gateway between the local network and the internet, directing data traffic and ensuring that devices such as computers, smartphones, and smart appliances can communicate with each other and access online resources. Many modern routers combine the functionalities of a modem as well, allowing for a seamless connection to the internet service provider. They often come with built-in security features to help protect your network from unauthorized access.
