Best-case math from the speeds you enter (1 GB = 8,000 megabits). Real uploads often take longer because of Wi-Fi, busy hours and the site you upload to. Not an offer or a speed at your address.

Common questions

Is fiber internet better than cable?

Often, but not always. Many cable plans download quickly too. Fiber's usual edge is upload speed and steadiness at busy times, so it matters most for video calls, uploads and gaming. Compare the exact plans offered at your address.

What is the difference between fiber and cable internet?

Fiber sends data as light through glass lines. Cable uses the same coax wiring that carries cable TV. In practice, that usually means fiber uploads faster and stays steadier at busy hours, while cable is offered at more addresses.

Is fiber worth it if I mostly stream?

Streaming mainly uses download speed, so a good cable plan can be enough. Fiber is worth more if you also make video calls, upload files or game.

How do I know if fiber reaches my home?

Only the provider can confirm service at your exact address. Enter your ZIP to see reported plans, then confirm the address with the provider.

Does cable internet have data caps?

Some cable plans do and some don't. Ask the provider and read the plan's terms before you sign.

What equipment do fiber and cable need?

Fiber usually connects to a small box called an ONT, then to a router. Cable uses a cable modem on a coax outlet. Ask whether equipment is included, rented monthly or yours to buy.

Is fiber internet worth it over cable?

It can be if uploads, video calls or steady evenings matter to you. If you mostly stream, a good cable plan may be enough. Before switching, compare the price after any promotion, install fees and whether you would owe an early-cancellation fee.

Which is cheaper, fiber or cable?

Neither is always cheaper. Prices depend on the provider, plan and address, and promotions often end. Compare the monthly price after the promo and any equipment fees.
