3 Ways to Configure Your PC to a Local Area Network – wikiHow

If your installing a permanent LAN solution, you’ll want to keep cable length in mind. CAT5 Ethernet cables should not run longer than 250 feet. If you need to cover larger distances, you’ll need switches at regular intervals, or you’ll need to use CAT6 cables.

To create a LAN, you’ll need a router and/or a network. These pieces of hardware are the “hub” of your LAN, and all of your computers will be connected to them.

This port may be labeled “INTERNET” instead. This will provide internet access to every computer that is connected to your LAN.

Connect the switch to a LAN port on the router. If you’re using a network switch to connect more computers, connect it to one of the LAN ports on the router. You can use any open port on the switch to make the connection. When connected, the router will provide IP addresses for every computer that is connected to either device.
