How to Use a Router to Split an Internet Signal Wired

Internet routers allow you to split a single Internet source between multiple computers and other devices such as gaming systems or internet TV devices. Routers are available for wired as well as wireless connections, though both generally have at least four wired ports. The router manages the data exchange between each device and the internet by assigning a unique IP address to each device, automatically funneling the data to the right device.

Things You'll Need

• Broadband modem (such as DSL or Cable)
• Ethernet cables

Instructions

1. Unplug the power to your broadband modem.

2. Plug an Ethernet cable into the Ethernet port on your broadband modem. Plug the opposite end into the "Internet" or "WAN" port on your router.

3. Reconnect the modem to an electrical outlet and wait for the modem to establish its Internet connection.

4. Connect the router to an electrical outlet and wait for it to make a connection to the modem. The "Internet" or "WAN" light on the front of the router will stay lit when a connection is established.

5. Plug an Ethernet cable into one of the numbered ports on the rear of the router. Connect the opposite end to your computer. Repeat this for any other computers you wish to connect to the router.

6. Open a web browser on each computer and test the Internet connection.

Tips & Warnings

• Most routers use a web-based settings menu. To change the router settings, open a web browser from a computer connected to the router. Enter the default address of the router, which is typically "192.168.1.1" for LinkSys routers and "192.168.0.1" for Netgear routers. The default address, username and password are available from your user manual or the router support website.
