You don’t need a lot of speed to stream music and video, but all that bandwidth adds up when multiple users access your DSL connection simultaneously. Get CenturyLink’s DSL internet if you don’t need more bandwidth than 200 Mbps.

CenturyLink’s fiber prices are on par with Frontier’s. You can get a 500 Mbps plan for $50 per month from either provider—there’s only a $5 difference between their gigabit plans. What CenturyLink lacks is a multigig fiber plan to compete with Frontier’s 2 Gbps fiber internet.

Like Frontier, CenturyLink has unlimited data on all of its plans—a big plus for heavy internet users.

If speed is what you need from a DSL connection, then CenturyLink is your best option of the two.

But with fiber, Frontier matches CenturyLink in price with its 500 Mbps plan. If you need gigabit speeds, Frontier’s plan costs $5 more a month than CenturyLink’s similar plan, which adds up to $60 more per year.

Frontier also offers a fiber plan with speeds up to 2,000 Mbps, whereas CenturyLink does not. Frontier is one of several internet providers in the US currently offering a 2 Gbps fiber plan, but it is the most expensive, costing more than similar plans from AT&T, Google Fiber, Optimum, and Verizon.

Speed: CenturyLink vs. Frontier

CenturyLink has the fastest DSL plan of the two at 140 Mbps, but you may see speeds topping out at 100 Mbps, depending on where you live.

CenturyLink and Frontier offer matching gigabit fiber plans, although Frontier costs $5 more each month. They also have matching 500 Mbps plans at the same price, but CenturyLink is the only provider of the two with a 200 Mbps fiber plan if you don’t need a lot of bandwidth.

Frontier has the fastest fiber plan of the two with speeds up to 2,000 Mbps (2 Gbps) for around $150 per month. Similar plans from AT&T and Google are cheaper if available in your area.

Extra fees: CenturyLink vs. Frontier

CenturyLink and Frontier have dramatically reduced their fees and costs over the years. What remains for both providers is a low-cost service at a price that should remain stable for the duration of your agreement.

CenturyLink fees

Installation$15.00–$99.00 (free with gigabit fiber)

CenturyLink’s service is considerably streamlined, with the only guaranteed fee being taxes on the network itself. Installation costs vary based on location (if your home already has a fiber or cable line running to it, you won’t have to pay for it) and taxes also vary based on states and municipalities.

The only consistent fee for CenturyLink customers will be for equipment, which can be negated by buying a DSL modem or router. We provide a few resources to get you started:

Frontier fees

Activation$85 for DSL; free for fiber
EquipmentNo fees

Frontier currently doesn’t charge an installation fee for DSL or fiber internet, but you must pay $85 to activate DSL service. Frontier also doesn’t charge a monthly fee for its DSL modem or wireless gateway, giving it an edge over CenturyLink.

CenturyLink scored near the bottom of internet providers when it comes to overall customer satisfaction, but scored slightly higher in terms of price satisfaction in our HighSpeedInternet.com customer satisfaction survey.

Contracts: CenturyLink vs. Frontier

Frontier requires a one-year contract for its fiber plans—there’s no annual contract for its DSL service. Discounted pricing for its Fiber Internet 500 plan ends after 12 months, while the discount extends out to 36 months with its Fiber Gig plan. There is no discount with its Fiber 2 Gig plan.

CenturyLink doesn’t require contracts at all, regardless of whether you opt for fiber or DSL, allowing you to cancel at any time. It also locks in its prices for life, just as long as you remain on that specific contract.

Internet connection types: CenturyLink vs. Frontier

CenturyLink and Frontier primarily offer DSL internet, which runs over existing telephone lines. Fiber-to-the-home is a completely new connection type and installation from the street to your wall, so those plans aren’t as widely available. DSL has slower download and upload speeds (topping out at 140 Mbps), while fiber is capable of much faster download speeds and symmetrical upload speeds.

Get a fiber connection over DSL if it’s available to you.

Installation: CenturyLink vs. Frontier


Installation fee: $15–$99 (free for gigabit fiber)

Installation type: Pro and standard install



Schedule an Installation


Activation fee fee: $85 for DSL; free for fiber

Installation type: Pro install only



Schedule an Installation

CenturyLink installs your DSL or fiber service for $99, but you can get standard installation (basically a self-install kit) for $15. Frontier installs DSL and fiber for free but it charges $85 to activate DSL service—fiber activation is free.

With CenturyLink, you need a professional installation (which includes network setup) if you don’t have a DSL or fiber jack. If you do have an existing DSL or fiber jack, you can opt for DSL standard installation.

Installing CenturyLink’s DSL equipment is a fairly straightforward process. Just plug in a few cables here and there, and then configure your network settings. If you need help, check out CenturyLink install guide.

Frontier does not offer a self-install kit at this time.


Renting is simple: you can go to a CenturyLink or Frontier brick-and-mortar store and get the equipment you need. They can also mail your equipment or send it with the technician when he comes to install service. DSL internet is usually easy to install yourself if you already have a telephone line. Fiber almost always requires a technician to set up.


Invest in a store-bought DSL modem and router (or a single DSL gateway) if you aim to keep your DSL plan for a while. You’ll have more control over your internet connection, but you may not see significant speed and performance advantages. Compatibility may be an issue too, so be sure to check with CenturyLink or Frontier to see which equipment is compatible with their DSL services before you purchase.

Fiber, on the other hand, is a tricky thing. There’s no modem involved unless you have cable TV or phone service too. Generally, the only device you can safely swap out in a fiber setup is a standalone router, which may or may not improve your wireless speed over the provider’s equipment.

CenturyLink has pretty dispersed coverage across the US, but its lines aren’t all the same. Some areas have DSL only while others (usually metros) have fiber. If you live in a more rural part of the county, CenturyLink likely has coverage.

Frontier has the fastest fiber plan of the two, but its fiber network in general is far less available than CenturyLink. You can find its fiber in Tampa, Myrtle Beach, Fort Wayne, and several other areas.

Final call: CenturyLink vs. Frontier

CenturyLink is the clear winner when it comes to DSL internet. You can get speeds up to 140 Mbps for $50 per month, which isn’t too shabby in our book when you compare other DSL plans.

Fiber is a mixed bag, however. Frontier offers the fastest fiber plan of the two with speeds up to 2,000 Mbps, but it costs more than similar plans from AT&T, Optimum, and Verizon. CenturyLink has the slowest fiber plan of the two at 200 Mbps for $30 per month. Both have 500 Mbps and 940 Mbps plans at nearly the same price.

That said, we say go with fiber if it’s in your area. You really can’t go wrong with either one in terms of dollar per megabit. But if you can’t get fiber, go with CenturyLink’s DSL internet, as you get more bang for your buck.

FAQ about CenturyLink vs. Frontier

What’s the difference between fiber and DSL?

DSL internet uses existing phone lines. It’s old technology that’s available nearly everywhere, but it caps at 140 Mbps in download speed. The newer fiber connections ditch old-school phone lines for glass fiber ones. It powers the internet backbone and delivers residential speeds at up to 10,000 Mbps both ways. Frontier stops at 2,000 Mbps for now.

Check out our full DSL vs. Fiber article for a deeper comparison.

Do CenturyLink and Frontier have data caps?

Frontier and CenturyLink no not have data caps. You’re free to use as much data all month as you please.

Is it cheaper to buy or rent equipment?

Whether or not it’s cheaper to buy or rent equipment depends on how long you plan to keep your internet plan. If you stick with one provider for two or more years, buy your equipment outright if it saves you money in the long run. Just keep in mind the possible upgrades and replacements you may need later—they come out of your pocket if you buy. Otherwise, rent your equipment if you plan to change plans in a year or less—anything you buy now may not be compatible with your new plan.
