What Is Cable Internet?

Cable internet runs over the same coaxial cable infrastructure that delivers cable TV service. It's the most widely available high-speed internet technology in the US — reaching roughly 89% of all homes — and is offered by providers like Xfinity, Spectrum, and Cox.

Cable is fast enough for most households and is generally more affordable than fiber at the same download speed tier. The main drawback is slower upload speeds and a shared network that can slow down during peak hours.
