Method 3 of 4:

Using a Wired Network on Windows

  1. Set Up a Computer Network — Using a Wired Network on Windows screenshot 31
    Make sure that you have the necessary hardware. You'll need an Internet source (e. g., a router) into which you can plug each individual computer, as well as Ethernet cables to connect the computers to the Internet source.
    • Most standard routers only come with a few Ethernet ports, but you can buy network hubs that support upward of 10 connections.
    • Make sure that you know the approximate distance from each computer to the Internet source. You'll need Ethernet cables that can span this distance.
  2. Set Up a Computer Network — Using a Wired Network on Windows screenshot 32
