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

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.

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. Some of Xfinity’s plans require contracts (dependent on region), 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 500 Mbps plan ($55.00/mo.) is the same price as CenturyLink’s DSL plan, with guaranteed maximum download speeds.

The next plan up, 1 Gig ($70.00/mo.), gives you 1,000 Mbps. That’s six times faster than CenturyLink’s highest DSL speed for just $15 more a month. Definitely worth the splurge.

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 Up to 40-80 Mbps DSL internet plan costs $55.00 whether you’re getting 40 or 80 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.

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 1 Gig plan, you get speeds of 1,000 Mbps (download) and 100 Mbps (upload). CenturyLink’s Fiber Internet gives you more reliability, plus up to 940 Mbps (down and up)—for just $5 more per month.

So, if you can get fiber where you live, that’s what you want. CenturyLink’s Simply Unlimited Internet 100 Mbps can work if your address gets a download speed of at least 100 Mbps, but if you can’t, it’s much less of a deal.

Installation

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 $100, though? That’s up to you.

Modems

Whose computer-talk box is better?

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.

Bundling Xfinity internet or CenturyLink internet with TV

Xfinity offers internet, TV, and phone bundles that include 10–185+ channels and internet speeds up to 2,000 Mbps. Xfinity has some sweet bundle discounts, too, so the more services you sign up for, the better the deal.

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.

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 500 Mbps plan costing just $55.00/mo., five times faster than CenturyLink’s highest DSL speed for the same 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.
