Why is Fast Internet Important?

Accessing information on the go quickly, streaming your favorite movie or playing games are all good reasons to want high-speed internet. Luckily, it’s easier than ever to obtain it. Many internet providers offer high-speed plans that vary in download and upload speeds depending on your area and the type of service.

Download speeds measure how fast it takes to fulfill your request, like downloading a movie. Your upload speed measures how fast you publish something to the internet, such as posting a video to YouTube. For high-speed internet, a good download speed is at least 25 Mbps. Some examples of speeds:

  • Downloading a movie: Slow: 5 Mbps Fast: 20 Mbps
  • Uploading a video: Slow: 2 Mbps, Fast: 25 Mbps
  • Downloading large files: Slow: 5 Mbps, Fast: 40 Mbps 
  • Email browsing: Slow: 1 Mbps, Fast: 20 Mbps 
  • Streaming video: Slow: 3 Mbps, Fast: 25 Mbps

Compare High-Speed Internet Providers

Along with connection speeds, there are other factors you should consider when choosing a high-speed internet provider. Most important is availability as all providers won’t be in your area. 

What’s more, does the provider have data caps? Data caps are the amount of data usage you have in one month before they throttle your connection speeds. This is where you’ll still be able to connect to the Internet, but you’ll have slower download and upload speeds. If you do a lot of gaming online, then it’s vital to consider if the provider has a data cap. 

Lastly, does the provider make you commit to a contract to have service? Some do, and if you go with one that does and cancel early, you could have to pay an early termination charge.

With these factors in mind, here are how each of the top providers measures up:

High-Speed Internet Frequently Asked Questions

What is the fastest internet speed I can get? 

It depends on the provider in your area. 1,000 Mbps or 1 GIG internet is the fastest internet available, but is not available in all areas. It also depends on the kind of internet available: fiber, cable or DSL. 

Is 100 mbps considered a fast internet speed?

In the U.S., 100 Mbps is fast. If you have an internet provider that has 100 Mbps plans, you can do most things, like gaming, downloading files or streaming videos, without lag times or buffering issues. However, a lot of cable and satellite providers only offer lower speeds and 100 Mbps is not available in all areas. 

How can I boost my internet speed?

There are a couple easy ways to boost your speed. Change your current modem or router, scan for viruses, check for external interference, shorten and replace cables, update firmware and software regularly, find your router/ISP’s best settings, check the cabling and do a line test. 

How much does fast internet cost?

That depends on your internet provider. In the eight providers above, fast internet is priced between $44.99 and $109. Sometimes new customers can find a deal or a provider will run a promotion that will help keep costs down initially. It’s also good to know that not all providers can offer fast internet in all areas of the country, so it’s best to do your research before signing up.
