How to Connect a Cable Modem to a Wireless Router

First the Internet revolutionized communication, then wireless technology changed how we use it. Wireless routers allow us to not only use the Internet almost anywhere, they also allow multiple devices to use a single Internet connection without the hassle and expense of wiring the house or building. If you want to join the couch computing club, you need to set up a wireless router to work with your cable modem.

Step

Disconnect the cable modem's power cord.

Step

Look at the back of the modem. Locate an Ethernet port. It looks like a phone jack, but slightly larger, and may be labeled "Ethernet," "Eth" or "Link."

Step

Connect a Category 5e Ethernet cable to the Ethernet port. It only goes in one way -- again, like a telephone jack -- so be sure it's right.

Step

Look at the back of the wireless router. There may several Ethernet ports. If there are, locate the one that is by itself. It may be labeled "Internet" or "Modem."

Step

Connect the other end of the Ethernet cable to this port.

Step

Connect the power cords for the cable modem and wireless router. Take care not to mix them up.
