A wired router is a networking device that enables communication between different devices on a local network. It uses physical cables, such as Ethernet cables, to establish a connection between devices, allowing for the transmission of data between them. Wired routers are often used in businesses, homes, and other environments where a reliable and secure connection is required. With a wired router, you can create a stable and high-speed network connection that is not affected by wireless interference or signal loss.
