How Does Cable Internet Work?

Cable internet service utilizes the same coaxial cable network that cable television companies use to supply your home with internet. Your internet service provider transmits a data signal through the coaxial cable, or coax cable, directly into your house—precisely, to your modem.

The modem then employs an Ethernet cable to connect to your PC, laptop, or router, giving you access to a high-speed internet connection. If you opt for using a router, you can then transmit a Wi-Fi signal all over your house.

Cable internet service providers send out data from a server to another employing this coaxial cable. Because TV itself only takes up only a small portion of the cable’s bandwidth, it leaves room for internet service to operate within the same network.

These cable networks extend all over the country, and there are also undersea cables that reach between water-separated locations. Additionally, cable internet can easily and efficiently distribute speeds evenly among individual users. It also means that you have access to more bandwidth if you pay more, meaning faster speeds.

Cable bundle benefits and savings

It is well-known that most TV and internet service providers have better offers when you combine both services together given that both services can operate through the same network.


This term makes reference to your network’s capability to transmit data. Imagine that your coax cable is a tube that transfers data like a hose that transfers water. A coax cable can send out enough data for both TV and internet service. In order to get faster speeds, you have to get more bandwidth.


A modem is an electronic device, typically a box, that receives data from the cable provider’s network and then delivers it to the house. The modem can be connected directly to a computer or to a router to spread Wi-Fi.

Network interface card (Nic)

To have access to an internet connection on your computer, you also require a network card. These are either plugged into expansion slots on your computer or incorporated into the computer already.

A network adapter is the built-in form of a network card, which means that your computer has it integrated without requiring an expansion slot.

Ethernet cable

It connects your modem to your computer or router; an ethernet cable can connect different devices directly to the internet for a more stable and faster signal connection.


A router is a device that distributes your modem’s direct signal into a Wi-Fi signal. It can also function as an Ethernet hub for other devices. Modems and routers can be combined and sold as one unit, often known as a gateway.

Mbps (Megabytes per second)

This term indicates the amount of data that can be transferred within one second. It is also possible to see speed measured in Gbps (gigabits per second), given that cable internet is now capable of reaching gigabit download speeds. However, Mbps remains the most popular term used when it comes to measuring internet speeds.
