Compare Cox vs. CenturyLink head to head

We think CenturyLink’s fiber internet plans provide the best value, provided one of the two fiber plans is a good fit for your needs. Each plan provides a lot of speed for the money and steers away from the price hikes and extra fees you might get with Cox. We absolutely do not recommend going for CenturyLink’s DSL over Cox’s cable internet (or any cable internet service). DSL isn’t up to the task of fulfilling modern bandwidth needs.

Cox has an advantage when it comes to mid-tier variety, with more plans to choose from. This makes it easier to find the perfect speed vs. price fit for your household. Additionally, Cox has better availability and higher customer service ratings than CenturyLink; so not only is the service easier to get, but you’ll likely have a better customer experience with Cox.

Plans and pricing: Cox vs. CenturyLink

Cox has a lot to choose from, including some impressive, budget-friendly packages. CenturyLink has just two packages—slow DSL or much faster fiber—but either way you get great perks like unlimited data and a month-to-month contract.

Fast speeds and wide availability—but slow uploads and big price hikes

Cox has great prices (at least up front) and a lot of options for customers to pick from. Most customers would be best off with one of the mid-tier plans, Go Faster and Go Even Faster. It’s Cox’s Go Faster plan which really fills the mid-tier hole in CenturyLink’s plan roster; you get an adequate speed at a good price. Cox also offers a prepaid plan called StraightUp Internet, which we like because it doesn’t require an annual term agreement and comes with a modem as part of the monthly fee.

The speeds you’ll get on a Cox plan range from a modest 100 Mbps all the way up to 2,000 Mbps. The 100 Mbps Go Fast plan is relatively cheap up front, but we’re not so keen on the big price hikes that come after 12 months of service. Depending on the plan you have, your bill could go up significantly or even double in price after 12 months of service. That might put some of the faster plans out of reach for some users, while the budget plans aren’t as plum of a deal after a year.

Cox (whose parent company is cable TV provider Cox Communications) also charges some extra fees, not all of which you’ll have to deal with from CenturyLink. Cox’s internet plans come with annual contracts. If you cancel your plan before the year is up, you’ll have to pay $10 for every month left on your bill. You can waive the term agreement, but it will cost you $10 more per month on your bill.

Cox low-cost internet plans

Cox has two great low-cost internet plans for individuals and families receiving government assistance:

ConnectAssist package : up to 100 Mbps for individuals receiving government assistance.

Connect2Compete package : up to 100 Mbps for families with children K-12 receiving government assistance.

CenturyLink Fiber Gigabit Internet$75.00/mo.|940 Mbps

Fiber firepower or dozing DSL—take your pick

CenturyLink Fiber Internet plans both deliver superb speeds for the money—if it’s available in your area, then we say go for it. CenturyLink’s Fiber Gigabit plan costs about $35 per month less than Cox’s gigabit plan; it matches Cox on speed and goes one further by giving you symmetrical upload speeds, which is perfect for backing up files to the cloud, spending time on Zoom, and posting to social media.

The only drawback to CenturyLink’s fiber plan is that it has much lower availability compared to Cox. And CenturyLink’s other option, Simply Unlimited Internet, isn’t quite as rosy—a straightforward DSL plan, it gives you unlimited data but relatively sluggish speeds. Technically a DSL connection can hit 100 Mbps, but what you can get depends on what’s available in your area, which could be much slower. The price also isn’t the best considering the technical limitations, although it’s more or less similar to Cox’s budget-tier plans.

CenturyLink$15/mo. or $200 to own$99.00 for professional install; free for self-install; $85.00 for phone jack install or DSL (if needed)Late fee is $5 or a percentage of your total bill

Cox and CenturyLink both charge fairly standard fees. Cox’s rental modem is cheaper than CenturyLink’s. But Cox also has early termination fees for customers who cancel an internet plan before their annual term agreement is up.

Pro tip: Buy a router to save money

Renting a router from your provider is the easiest way to go, but it isn’t very cost effective—you’ll be running up rental costs till the end of time when you could simply buy your own equipment instead.

Buying your own modem and router also lets you choose more up-to-date equipment with additional speed, security, and parental features.

We have more info on buying routers farther down on this page, so take a gander for recommendations into the best equipment.

OverallSpeedPriceReliabilityCustomer service

CenturyLink doesn’t offer any bundle deals on internet and TV service. But Cox offers some solid bundles through its cable TV service, Cox Contour . Bundles give you a bit of a discount on TV and internet by letting you combine them. The cheapest Cox bundle gets you 100 Mbps of internet speed and 75 channels, but you have Cox bundling options that go up to 2,000 Mbps and 250 channels.

Internet types: Cox vs. CenturyLink

Internet typeDetails
Cox Communications
CableView Plans

Fiber, DSL

Cox has cable internet, which runs over the same coaxial copper wiring as a cable TV network. Cable is fast, reliable, and widely available—our only quibble is that it doesn’t give you the fast upload speeds like you can get with fiber.

CenturyLink delivers both DSL and fiber internet. Fiber-optic internet is by far the best internet around, since it can hit the fastest speeds possible and is impervious to the kinds of electromagnetic interference that can hamper cable and DSL lines. It has a much lower availability nationwide, but hopefully that changes in the coming years.

DSL is an old-school type of internet that gives you a connection over the copper wiring of your landline phone network. It tops out at 100 Mbps—a fraction of the speed you can get over cable or fiber—so it’s best if you have minimal internet needs and if you don’t share your Wi-Fi with more than a few others in your household.

Data caps: Cox vs. CenturyLink

Data capOverage feeDetails
Cox Communications
1.25 TB$10 per 50 GBView Plans


Cox has a 1.25TB cap on all of its internet plans. That’s a pretty generous cap—it will be just fine for most people—but you’ll need to be more budget-conscious of your data use if you live with a lot of people and like to stream video in 4K. The more users on your Wi-Fi, the faster you’ll burn through data, and overage charges can really add up.

CenturyLink, on the other hand, has no data caps—yay! That means you can spend all the time you want attending Zoom meetings, streaming movies and TV shows, and downloading files from your email. No need to worry about network slowdowns or overage charges.

Pro tip:

A lot of internet providers have raised their data caps over the years, and some don’t have data caps at all. See our guide to data caps to find out which providers give you data limits and which don’t.

Contracts: Cox vs. CenturyLink

Contract lengthEarly termination feeDetails
Cox Communications
1 yr., month-to-month option for $10/mo. extra$10 per each month left on contract (up to $120 or $240 depending on length of contract)View Plans


CenturyLink has month-to-month contracts with annual term agreements. That means you can cancel your internet any time and you won’t have to pay an early termination fee, the dreaded fee that goes up with each month you have left on your contract.

Cox lets you choose between getting a package with an annual contract or without. If you cancel early on a plan with a contract, you’re on the hook for $10 for each month you have left in the agreement. If you pick a plan with no annual contract, well, you pay $10 extra per month on your bill. You’re not gaining much that way, so you may as well just sign up for the plan with the annual contract.

Installation: Cox vs. CenturyLink

Installation optionsDetails
Cox Communications
$100.00 for professional install; free for self-install kitView Plans

$99.00 for professional install; free for self-install; $85.00 for phone jack install or DSL (if needed)

The official price for professional installation from CenturyLink is $99—but lately the internet provider has been offering installation free of charge, with no extra charges added to your bill. However, you may need to pay an additional $85 to install a phone jack for DSL service if you don’t already have one in your house.

Cox charges $100 for professional installation, which means a technician will come over to your home and set everything up. You can save money by installing your new cable setup yourself—an Easy Connect self-install kit doesn’t cost anything extra.

Availability: Cox vs. CenturyLink

Cox is available in 29 states, and you can find CenturyLink in 36 states. CenturyLink has a much bigger US network overall—more than twice the size of Cox’s service footprint. But there’s a lot of overlap between the two providers, and the best way to figure out availability where you live is by using our zip code tool below.

Final call: Cox vs. CenturyLink

If you want gigabit speeds, CenturyLink’s Fiber Gigabit plan is the clear winner. You get much faster upload speeds on that plan, along with unlimited data and no annual contract requirement. If 200Mbps is enough speed for your household, CenturyLink’s Fiber Intenet 200Mbps is also a better value than Cox’s budget plans.

If you’re looking for something more mid-range, Cox’s plans are worth a look. There’s no benefit to purchasing more internet speed than you need.

Fiber isn’t available everywhere, and CenturyLink’s DSL plan is a lot slower than what you can get from Cox. Internet customers who need robust speeds for work or entertainment (or both) would be wise to go with Cox if fiber isn’t available. Cox is also the best option if you want internet and TV in one bundle package—and its excellent customer service ratings mean it’s a solid bet for folks who aren’t super tech-oriented.

CenturyLink’s DSL plan isn’t the fastest thing out there, but it has some strengths. You won’t need to sign up for an annual contract, and you’ll get all the data you need. For most customers, we recommend the DSL plan only as an alternative to satellite internet.
