How to Set Up a Wireless Modem and Router

By Contributing Writer

Running your computer or other device through a wireless modem or router is a convenient way access the Internet from anywhere in your home. Setting up the wireless network allows more than one computer or device to access the Internet at a time. You will need a modem connected directly to the Internet with either an Ethernet cord (DSL) or cable cord (cable). Make sure that your service has been activated through your Internet service provider before attempting to set up your home network. Some modems come with wireless capabilities already installed, requiring no need for a router. If this is the case, omit steps two through eight.

Things You'll Need

  • Ethernet or cable cord

Step 1

Turn on your modem and make sure that it is ready to access the Internet. Some modems require time to load up.

Step 2

Disconnect the modem if it is connected to a computer.

Step 3

Take the cord that was just disconnected from the computer and place it into the port labeled "Internet" on the back of the router. If the modem was not connected to a computer, connect an Ethernet cord to the back of the modem--there should only be one slot--and then connect it to the port labeled "Internet" on the back of the router.

Step 4

Place another Ethernet cord into one of the ports on the back of the router--these should be numbered--and connect it to the back of the computer.

Step 5

Turn on the router and allow it time to load up. You should also turn on your computer at this time.

Step 6

Install any software that came with the router, if required.

Step 7

Type in the password/encryption code to originally set up your modem. This can normally be found on the bottom or the back of your modem. If you cannot locate it, contact your modem's manufacturer or the person who originally set up your connection for assistance.

Step 8

Allow your computer to access the Internet. Your computer should now be able to access the Internet via the router. If you cannot access the Internet, check the instructions that came with your router or contact your Internet service provider to troubleshoot the problem.
