Best Cable Internet Provider: Spectrum

One of the cable internet providers we're sure you've heard of is Spectrum - and for a reason. Spectrum Internet offers solid coverage in a good chunk of the nation.

We've chosen Spectrum for the best cable internet provider. Here's why:

  • Coverage - Check Spectrums coverage map to see if you're in one of the 24 states they cover.

  • Buyout - Spectrum will buy out your old contract so you can switch to them. So if you're looking to switch and pair TV and phone with your internet Spectrum will cover your fees up to a certain amount.

  • Improvements - Ever since Charter acquired Time Warner Spectrum and rebranded into Spectrum customer service has drastically improved.

  • Promotions - Oftentimes Spectrum offers deals or sign-up bonuses. Just be sure to check the fine print.

But Spectrum isn't perfect. Here are some of Spectrums' downfalls.

  • Bill Increases - Remember those promo deals we mentioned earlier? Oftentimes your promo price ends before your contract is up.

  • Expensive - Spectrum is a pricier option than some other internet providers. So continue on if you're looking for a budget-friendly option.

Key Considerations When Choosing a Cable Internet Provider

Internet providers frequently advertise deals and offers, however finding information in the fine print is still quite a task. Before frantically looking for the right provider it's best to figure out what you want out of your provider.

So ask yourself:

  • What providers cover your area? You can use our availability checker to search for internet providers by zip code.

  • What type of connection are you looking for? Are you looking for cable internet, fiber-optic, DSL or satellite internet?

  • What's more important: Price or Speed? Unfortunately, oftentimes you have to choose.

Cable Internet Benefits

There are several benefits to having cable internet connectivity.

  1. Convenience - If you're one of the vast majority of households with existing cable service, it's fairly simple to add the internet because the wiring is already in place, for the most part. All you really need is to have a cable modem installed and your service activated.

  2. Connection Quality - Wired connections in general naturally offer better and more reliable quality than, say, mobile broadband or satellite internet. Environmental factors such as weather do not cause interruptions in data transmission.

  3. Speed - The vast majority of DSL connections max out at between 15 and 20Mbps. Satellite internet is even slower, at a maximum of 10 - 15Mbps download speed. Cable internet speed can be affected by certain factors, however, which I will cover later in this guide. No matter which plans you have, cable internet upload speeds are always significantly slower than download. Upload speeds range between under 1Mbps and 5 - 8Mbps.

High-speed internet providers are increasingly using FTTN (fiber to the node, or fiber to the neighborhood) to increase the speed of their cable internet offerings. This means they're installing fiber optics from the hub to the street, which gives you faster speeds even though the wiring to your home is still via coaxial cable.

Well, MoCA technology is a protocol that allows the distribution of content over existing in-home coax TV cabling. The main function of MoCA tech is to guarantee the delivery of packets to their destination. You can learn more with the MoCA organization FAQ.
