Instructions for Hooking Up Time Warner Cable Internet to a Computer


Time Warner Cable offers a few different high-speed Internet services, including EarthLink and the several variants of Road Runner Broadband. All of these work by routing Internet communication through the coaxial cable in your home normally used for television. In order to accomplish this, a special device called a cable modem is connected to the coaxial cable and to your computer. The cable modem acts as a go-between, relaying messages from your computer out over the cable, and vice versa.

Things You'll Need

  • Cable Modem
  • Coaxial Cable
  • Ethernet Cable (optional)
  • USB Cable (optional)
  • Connect the coaxial cable to the connector on your wall. If you already use this connector for your television, you will need to either use a connector in a different room or a splitter.

  • Connect the other end of the cable to the coaxial cable connector on your cable modem.

  • Connect the cable modem to your computer. If your cable modem has a USB port, then connect the USB cable to the cable modem, and the other end to a USB port on your computer. If the cable modem has an Ethernet port, connect it to the computer using an Ethernet cable. If the cable modem has both types of ports, do not use both. If your cable modem is built into your computer, no further connections are required.

  • Connect the cable modem to an electrical outlet using its power adaptor, and turn it on if it has a switch. The lights on the cable modem, if it has any, will begin to indicate whatever network activity is taking place. Refer to the cable modem's documentation to learn the precise meaning of the lights.

  • Install drivers for your cable modem on your computer if needed. If you use an Ethernet connection, you don't need to install drivers for the cable modem, but cable modems using USB and built-in cable modems require software drivers to operate correctly. Refer to the cable modem's documentation for information about software drivers.
