CenturyLink offers top internet speeds of up to 940 Mbps with its fiber service.
While that’s slightly under true gigabit speeds, 940 Mbps is more than fast enough for you and others to browse, stream, and game to your heart’s content.
CenturyLink’s fiber-optic internet is fast, but it isn’t available everywhere. Its Digital Subscriber Line (DSL) option is much more available, but it offers slower packages ranging from 10–100 Mbps.
The Internet Service Provider’s (ISP’s) speed test results make it look like most people probably choose CenturyLink’s slower plans.

Fastest Cities for CenturyLink Internet Service
|City||Top advertised download speed||Average download speed*|
|1. Kaysville, UT||940 Mbps||143 Mbps|
|2. Fort Collins, CO||940 Mbps||62 Mbps|
|3. Ocoee, FL||940 Mbps||59 Mbps|
|4. Tacoma, WA||940 Mbps||56 Mbps|
|5. Bellevue, NE||940 Mbps||56 Mbps|
It’s no surprise that CenturyLink’s speediest cities have access to fiber service. CenturyLink’s slower DSL internet service is much more widely available than its near-gigabit fiber option. But where fiber is available, it boosts speed test results for the area because it’s just so much faster.
Keep in mind that these are average speeds based on speed tests for entire cities and their surrounding areas. The results span all types of speed packages, times of day, types of internet, and other factors that affect speeds. Your actual internet speeds will mostly depend on which speed package you’re signed up for.

Internet Speed Recommendations
Everything you do online requires a certain amount of speed (or bandwidth). Binge-watching Gilmore Girls on Netflix, for example, needs about 3 Mbps. It also takes about 3 Mbps to scroll through social media. That doesn’t seem like much, but it can add up quickly if you have a lot of things going at the same time.
So, how much speed do you need? Well, you’ll need to think about how many people will use the internet and how they’ll be using it.
We’ve broken down the minimum internet speeds we recommend for everyday online activities below. But if you want a more personalized recommendation, check out our How Much Speed Do I Need? tool.

About our CenturyLink internet speed test
Our CenturyLink fiber and DSL internet speed test uses servers that adjust to your location for accurate results in about a minute. Some other speed tests use similar processes but use a fixed server, which can mess up your readings.
Using our speed test is a quick way to test your internet connection and make sure you’re getting the speeds you pay for.
How does the CenturyLink internet speed test work?
It’s pretty simple. The speed test uses your CenturyLink internet connection to download then upload a dummy file to your computer. It calculates your speeds by dividing the size of the file by the time it takes to complete the download or upload.
The test also measures how long it takes to send a signal—or ping—to the server and back to calculate your latency.
Here’s a short breakdown on what the test measures and how the factors affect your internet experience.
Download speed is how long it takes for information to get from the internet to your computer. Your internet plan probably has something like “up to 100 Mbps” in its name somewhere—that’s your download speed. This affects everything you do on the internet, including loading websites and streaming TV shows.
Upload speed is how long it takes for you to send information to the internet. Good upload speeds are essential for online gaming, video calls, and posting hilarious videos of your cat on Instagram.
Latency is the time it takes a signal to travel from your network to the internet server and back. While latency, ping, and lag are technically different things, the terms are often used interchangeably. The faster the signal travels, the lower your latency is. Low latency is particularly important in online gaming. How so? If you and your opponent pull the trigger at the exact same time, the one with the lower latency shoots first.
If you get less-than-stellar results on your speed test, try it at different times of day to see if it changes. The problem may be network congestion—when too many of your neighbors are using the same internet hub at the same time. If you’re still not seeing the speeds you need, it might be time to upgrade plans or change providers. Don’t worry—we can help you with that.

If you’re looking for fast CenturyLink internet speeds, you want fiber. Besides being newer and shinier (because it literally uses light signals), fiber-optic internet service is faster and more reliable than DSL.
You can see just how much faster it is by the max speed jump between CenturyLink’s top DSL plan (100 Mbps) and its fiber plan (940 Mbps). That’s the power of fiber.
And fiber service is reasonably priced compared to gigabit internet services from other providers. When it comes to price, all of CenturyLink’s plans are pretty good, especially considering they don’t lock you into a contract or play tricks with introductory pricing.
The Price for Life guarantee actually protects you from surprise price hikes down the road, which is refreshing.

CenturyLink internet speed FAQ
CenturyLink Fiber vs. CenturyLink DSL
CenturyLink offers both fiber and DSL internet services. Fiber is newer, cooler, and much faster. The downside is that fiber infrastructure is expensive, so it isn’t as widely available as DSL. If you have the choice between the two and really juice your internet connection with things like streaming or gaming, go with fiber.
How fast is CenturyLink Internet?
CenturyLink’s available speeds depend on where you live, but the ISP generally supports speeds ranging from 10–940 Mbps. The higher speeds are supported by CenturyLink’s fiber service, while a slower range is available on its DSL service.
What is a good internet download speed?
A good internet download speed is about 5–10 Mbps per person for normal use or 25 Mbps per person for HD streaming or frequent gaming. You can also check with our How Much Internet Speed Do You Need? tool for a personalized recommendation. Your internet speed needs depend on how you use the internet. If you only go online for email, recipes, or social media, you can get away with a much cheaper internet package than if you do anything with video.
How many Mbps is 4G LTE?
Theoretically, 4G LTE can reach up to 100 Mbps, and true 4G can reach up to 1,000 Mbps (or 1 Gbps). But in reality, most networks don’t perform that well. According to our speed test results, the major wireless carriers in the US have average speeds of 13–18 Mbps at the time of writing. These averages represent 109,838 mobile speed test results ranging from 0.002 Mbps to 849.117 Mbps.
How fast is CenturyLink LTE?
CenturyLink offers fiber and DSL residential internet with speed packages ranging from 10–940 Mbps. The ISP does not provide mobile service or 4G LTE at this time. The only way to get CenturyLink wireless internet is to connect a Wi-Fi router to your home network, and the speed of that connection depends on your internet package.
What is my internet speed?
If you want to know what your internet speed is, use our speed test. Whether you have a slow connection or just want to make sure you’re getting the speeds you pay for, periodically testing your internet is a smart idea.
