How to Connect a LAN Networkby Stephen Lilley
A LAN is a local area network of computers that are all connected to each other. Unlike a WLAN, which uses wireless technology to connect computers, local area networks use a series of Ethernet cables and a router. If you want to connect your computer to a nearby LAN for networking or Internet purposes, you'll need to use an Ethernet cable to connect your machine to the router.
Verify that there is a free input on the back of the LAN's router. A LAN only supports a limited number of connections, so if there is no free input on the back of the router you won't be able to connect your computer to the LAN. If a free input is available, continue to Step 2.
Plug the Ethernet cable into your computer. Computers typically have at least one Ethernet output. They are located on the back of the computer's case for desktops or on one of the sides for laptops.
Insert the Ethernet cable into the free input on the back of your LAN router. Once connected, your computer will be automatically connected to the LAN.
