Cable internet
Cable internet runs over the same coaxial lines that carry cable TV. It reaches most city and suburban homes and offers fast downloads at a fair price.
- Download speeds usually run from 100 Mbps to 2,000 Mbps.
- Upload is much slower, commonly 10 to 50 Mbps.
- The line is shared with neighbours, so speed can dip in the evening.
How cable works
The provider runs fiber to a neighbourhood node, then coaxial cable from the node to each home. A cable modem in your home connects to that line, and a router shares the connection over Wi-Fi. Many providers rent a combined modem and router, often called a gateway.
Download and upload
Cable networks give most of their capacity to downloads. A 500 Mbps cable plan might upload at only 20 Mbps. For streaming and browsing you will not notice. For frequent video calls, cloud backups or live streaming, the upload number is the one to ask about. Some areas have upgraded networks with much faster uploads, so it is worth asking what is offered at your address.
Busy-hour slowdowns
Homes on the same node share capacity. In the evening, when the whole street is streaming, speeds can fall below the advertised figure. A good provider manages this well, but it is the main difference in feel between cable and fiber.
Costs to check
- Equipment: gateway rental is often $10 to $15 a month. Most cable providers let you use your own approved modem instead.
- Data caps: some cable plans include a monthly data allowance, commonly around one terabyte or more, with a fee if you go over.
- Price after promotion: the first-year price usually rises. Ask for the regular rate.
Who should pick cable
Cable is a strong choice where fiber is not available. It handles several 4K streams, gaming and normal working from home without trouble.
Common questions
Is cable internet good for working from home?
Yes for most jobs. If you are on video calls all day or upload large files, check the upload speed of the plan and consider a higher tier.
Can I use my own modem with cable internet?
Usually yes. The provider publishes a list of approved modems. Buying your own can pay for itself in about a year compared with renting.
Why is my cable internet slower at night?
Your street shares capacity. When many homes are online at once, each gets a smaller share. If it happens every evening, report it to the provider.
