How to Convert Coaxial to Ethernetby Bryan Roberts
Regarding digital cable, coaxial cable serves two purposes in the home--it transfers a digital cable signal to televisions to allow for the viewing of digital cable, and transfers a cable signal to a computer to allow for cable Internet access. However, the signal sent by the coaxial cable must be converted to an Ethernet cable before it can be used by a computer. Achieve this conversion via a cable modem.
Connect one end of your coaxial cable to a coaxial wall port near your cable modem.
Connect the other end of the coaxial cable to the coaxial port on your cable modem.
Connect one end of your Ethernet cable to the Ethernet port on your modem.
Connect the other end of your Ethernet cable to an available Ethernet port on your computer.
Turn your computer and cable modem on. Your computer will detect the signal sent from the cable modem by the Ethernet cable.
