Router

A router is a device that forwards data between computer networks. The most familiar type of routers are home and small office routers that allow you to share your internet connection between multiple devices at the same time.

Routers can be wired or wireless. A wired router allows you to connect your computer using a Ethernet (RJ45) cable. Most wired home routers have four ports allowing you to connect up to four computers to the internet at the same time. A wireless router uses Wi‑Fi technology allows you to wirelessly connect your phones, tablets, computers, and other devices to the network.

Wireless routers can connect to several devices at the same time. For more information, see the documentation for your router.
