Xfinity vs. CenturyLink Internet 2023: Plans, Prices, and More

From fiber internet to the Xfinity Flex, we break down the biggest features of each provider.

Best for speed

Internet speeds: 75–6,000 Mbps

Internet speeds: 75–6,000 Mbps

Best for cheaper fiber

Internet speeds: Up to 100–940 Mbps

Internet speeds: Up to 100–940 Mbps

Is Xfinity or CenturyLink better?

Xfinity has fast, reliable cable internet packages and some super speedy (and super expensive) fiber plans. And its xFi Advanced Gateway is a pretty sweet modem/router combo.

But Xfinity charges more for no-contract plans, so if you want a more flexible option, go with CenturyLink. It has slower, less reliable DSL internet packages with fixed prices and no contracts, but you might get lucky and find yourself in a CenturyLink fiber internet location with superfast speeds.

We recommend Xfinity’s reliable cable internet over CenturyLink’s DSL internet for families looking to enjoy streaming and browsing at home. But CenturyLink’s fast fiber internet is a high-performing and affordable option (if you can get it).

Since cable internet technology is faster and more reliable than DSL, Xfinity has the edge over most CenturyLink plans. Most Xfinity plans require contracts (some are available month-to-month for a fee), but most of CenturyLink’s plans do not.

Regarding value, Xfinity’s cable plans are generally a better value than CenturyLink’s DSL plan. Xfinity’s Connect ($19.99 a month) and Connect More ($35.00 a month) are cheaper than CenturyLink’s DSL plan, with guaranteed maximum download speeds.

The next plan up, Fast ($50.00 a month), gives you 400 Mbps. That’s more than triple CenturyLink’s highest DSL speed for the same price (CenturyLink’s DSL plans are all $55 monthly, regardless of speed).

Plot twist! When we get into fiber speeds, CenturyLink’s a better value than Xfinity. We explore this more after the table.

CenturyLink’s Simply Unlimited Internet DSL internet plan costs $55.00 whether you’re getting 15 or 100 Mbps, thanks to the unpredictability of CenturyLink’s DSL network. On the plan, you’ll get the maximum internet speed that’s available at your address. But with CenturyLink’s no-contract pricing, you’ll pay the same rate and won’t have to worry about annual price increases in the future.

The CenturyLink Fiber Gigabit plan ($75.00 a month) gives you download and upload speeds up to 940 Mbps. For around the same price, Xfinity’s Gigabit plan ($60.00–$75.00 monthly) gives you 1,000 Mbps. Xfinity’s faster Gigabit Extra plan runs $70.00-$80.00 a month for 1,200 Mbps.

But now, instead of comparing CenturyLink DSL plans with Xfinity cable plans, we’re comparing Xfinity’s cable speeds with CenturyLink’s fiber internet. Fiber is faster and more reliable than cable, and only fiber gives you symmetrical download and upload speeds.

What does that mean? Well, with Xfinity’s cable Gigabit plan, you get speeds of 1,200 Mbps (download) and 35 Mbps (upload). CenturyLink’s Fiber Internet gives you more reliability, plus up to 940 Mbps (down and up)—for around the same price per month.

So, if you can get fiber where you live, that’s what you want. CenturyLink’s Simply Unlimited Internet can work if your address gets a download speed of at least 80 Mbps, but if you can’t, it’s much less of a deal.

Our recommendation

If you can’t get fiber at your location, any Xfinity plan from Connect to Fast gives you more bang for your buck than CenturyLink’s Simply Unlimited Internet DSL plans.

Deals and promotions

New customers can get unlimited Gig-speed internet and streaming for $50/mo. for the first two years when they sign up for a mobile plan with Xfinity. Learn more about Xfinity deals here.

CenturyLink offers a free modem and installation (combined $299 value) for new customers when they sign up for the Fiber Gigabit plan online.

Xfinity vs. CenturyLink fees and extra charges

Neither Xfinity nor CenturyLink hit you with fees or extra charges on your monthly bill. Huzzah!


Xfinity CenturyLink
Professional installation fee $89.99 $99.00
Standard installation fee N/A $15.00
Self-installation fee Free N/A
Schedule Xfinity install Schedule CenturyLink install

In the chart above, CenturyLink requires us to refer to its cheaper installation as “standard installation,” but don’t get it twisted—you’ll still be doing most of the install yourself. Xfinity’s self-installation is cheaper (yay, free!) and more forthright. Names aside, the cheaper DIY options are the way to go.

But don’t fret, technophobes: self-installation is easy. You don’t even have to do it yourself. Just order the self-installation kits and offer 20 bucks to a friend or neighbor. You’ll still save big over the pro-install price—and you won’t have to take time off of work to meet the installation tech.

Then again, letting the professionals do it does give you peace of mind. And it’s probably going to go faster since they do this stuff all the time, which means you can enjoy most of that half-day escape from work. Is that worth $90–$100, though? That’s up to you.

Xfinity’s xFi Gateway modem/router combos are popular with its customers—79% of them use one instead of a third-party option. The xFi Advanced Gateway XB7 is brand new and made for connections of at least 300 Mbps up to 1.5 Gbps.

You can’t buy the XB7 outright—you have to lease one from Xfinity for $14 a month. But leasing isn’t all bad because you’ll get free replacements if the unit fails and a free subscription to Xfinity’s Advanced Cybersecurity service (reg. $5.99 a month).

CenturyLink rents modem/routers for $15 a month and sells them for $200. But it won’t tell us which models go for that price. Instead, a rep sent us a list of CenturyLink-compatible devices. If you’d like to learn about those, here’s our guide to the best CenturyLink-compatible modems.

Although it’s 40% more expensive, we recommend Xfinity’s souped-up xFi Advanced Gateway over CenturyLink’s mystery box.

Customer satisfaction

In our customer satisfaction survey of 14 internet providers, Xfinity finished in 3rd with 62% approval. CenturyLink came in 7th place with 52% approval.

Xfinity trounced CenturyLink across the board in our survey, although CenturyLink customers still liked the internet provider’s strong value and relatively low costs.’s experiences with Xfinity and CenturyLink internet

Members of our team include both Xfinity and CenturyLink customers. We also do some secret shopping with the providers we cover. Here are some of our takeaways.


The Good: I have the Performance Starter plan, and my bill is only $29.99 a month for 60 Mbps. That said, I don’t always get that download speed and, at times, have to suffer through some buffering while I’m peeping Big Mouth. But it’s cheap, cheap, cheap, so I’m happy to suffer a little. —Mike Strayer, Managing Editor

The Bad: I’ve been with Xfinity for close to 20 years. New customers pay $34.99/mo. for the Performance plan. My current rate, which includes a longtime customer discount of $17 per month, is $49.99. —Randy Harward, Staff Writer


The Good: I’ve had CenturyLink DSL in the past. It wasn’t bad. I now have fiber and it’s been great. As far as I can tell, it hasn’t gone down once. —Bill Frost, Staff Writer

The Bad: I qualified for up to 1.5 Mbps, which is soooo bad. Despite this, CenturyLink still pushed me its base plan (15 Mbps) for $49.99, and the rep insisted that 1.5 Mbps would easily support multiple simultaneous HD streams and online gaming. Wow. —Randy Harward, Staff Writer

Bundling Xfinity internet or CenturyLink internet with TV

Xfinity offers two- and three-service bundles that include up to 260+ channels and internet speeds up to 1,200 Mbps.

Unfortunately, since breaking off its relationship with DIRECTV, CenturyLink does not currently offer bundling with TV—just home phone service. We’ll update this article if CenturyLink pairs up with a new TV provider.

Don’t wanna spend a bundle on a bundle? Try Xfinity Flex.

Unfortunately, the Xfinity Flex will no longer be free to Xfinity customers after April 2023. It offered 200+ free channels of live TV, access to Xfinity’s vast on-demand catalog, a sweet XR15 voice remote, and access to paid subscription service apps like Amazon Prime Video and Netflix. It was a great deal when it lasted! Check out our Xfinity Flex review for more details.

CenturyLink vs. Xfinity: which is better?

For equipment, reliability, speed, and value, Xfinity is your best bet. Xfinity’s cable plans all are better values than CenturyLink’s DSL plans, with Xfinity’s Fast plan providing 400 Mbps for $50.00 per month, more than triple CenturyLink’s highest DSL speed for almost the same monthly price. CenturyLink is limited by its DSL plans and mixed customer service, although its fiber internet plan is a great deal if it’s available in your area.

Xfinity vs. CenturyLink FAQ

Is CenturyLink DSL or cable?

CenturyLink’s internet plans are DSL and fiber.

What kind of internet service is Xfinity?

Xfinity is mainly a cable internet service provider, but it also offers a single fiber internet plan.

What is a good internet speed?

We suggest a minimum of 25 Mbps to accommodate all of the devices and services in your home. You can do a lot of streaming and gaming with that much speed, even on multiple devices at once.

Remember, though, that internet service providers guarantee only up to whatever speed comes with your plan. So you’ll first want to check with your provider to see what speeds you can get at your location.

If, after checking, you qualify for more speed than you need—and it fits your budget—consider paying for the next-fastest plan to accommodate for slow-downs that may occur.

Is DSL good for streaming?

DSL is good for streaming, but cable and fiber internet are faster and more reliable.
