Internet protocol television service connections use a variety of cable types to get the signal into the home. This is normally standard phone line, also seen in DSL broadband installations. Coaxial cable is used if the home is wired as such, preventing the need to run Ethernet cables throughout the structure. Once inside the home, coaxial cable takes over, directing the broadband signals from the router to the individual computers or network devices. Many major service providers are building this functionality, known as MoCA (Multimedia over Coax Alliance) connections, into all new products.
Locate the phone line coming into the home or structure. This is commonly found in the lower-level, basement or access room.
Video of the Day
Plug the phone line into the "Internet" port on the DSL router. Push it in until a click is heard and felt from the connector.
Screw a coaxial cable from the RF connector on the DSL modem to one of the input legs on the high-bandwidth splitter.
Locate the coaxial cable drop, normally located within close proximity of the electrical panel and/or the incoming phone line.
Screw each coaxial cable into the output legs of the high-bandwidth splitter.
Plug the router into AC power. Wait for the indicator lights on the front to flash green, indicating a positive connection to the incoming service.
Screw the coaxial cables from the coaxial jack plates in each room to the "Broadband" or "RF" ports on each computer or networked device.
Things You'll Need
Verify that your broadband modem card has the ability to use coaxial cable in lieu of Ethernet cabling. If not, small adapters are available at relatively low cost.
