How to Convert Cable to Ethernet

If you obtain your television programming through a cable provider, chances are you also use the company for your Internet connection. When doing so, the Internet streams through a coaxial cable, the same cable you use to access the Internet. However, your computer does not have a coaxial cable Internet connection, so you need to convert the connection into an Ethernet cable.

Convert a cable connection to Ethernet.

Step

Take the coaxial cable running form the wall—this is the cable connection running into your home—and attach it to the "WAN" port on the back of the cable modem. The coaxial cable has a threaded connector, so make sure you twist the cable on completely to secure the connection.

Step

Plug the Ethernet cable into one of the numbered "Out" ports along the side of the cable modem. It does not matter which "Out" port you use.

Step

Insert the other end of the Ethernet cable into the "WAN" port on the back side of your computer. Once the cable is inserted a light appears next to the cable, signifying the connection is complete.

Step

Power on the cable modem and open the Internet browser on the computer.
