How To: Wi-Fi Coaxial Cable to an RJ45

Adapting coaxial cable for a computer or video network is surprisingly easy, using the right adapters. Since there is no way to make a direct-wired coax to Ethernet cable, a converter and baluns are required to internally maintain the right impedance, while transmitting the signal over longer distances. These adapters convert the coaxial signals to Ethernet, where the high bandwidth easily carries the dense data from point to point. This leverages the Ethernet cable running through the walls, connecting devices that rely on coax.

Converting coax to RJ45 Ethernet is useful for long data runs.

Step

Screw the coaxial cable from the router to the coax to Ethernet adapter.

Step

Click the Ethernet cable's RJ45 connector into the "OUTPUT" side of the adapter.

Step

Break out the signal traveling over the Ethernet cable to the computer laptop. Snap the RJ45 connector into the balun. Screw the coaxial cable to the other end of the balun to the modem or other device.

Step

Plug the adapter into AC power, as needed.
