Bottom line

AT&T gives you fast fiber internet at an excellent price, making it the obvious first pick here—but you’ll need to watch out for price hikes 12 months down the line. And it may not be available in your area, since those fiber offerings are limited. CenturyLink is also good, especially if you’re tired of price hikes and promotional shenanigans. It has Price for Life offers on DSL plans, free self-installation, and other ways to save on expenses.

AT&T vs. CenturyLink packages and pricing

AT&T and CenturyLink both offer two options—DSL and fiber internet. Their DSL plans are decently priced and their fiber speeds are as fast as they come.

AT&T has some of the best ratings in the biz, so you’ll have less worries when it comes to technical support and customer service. CenturyLink, on the other hand, is a great pick if you simply want to save some cash. You can buy a CenturyLink modem instead of renting it, and you can get installation for free if you elect to do it yourself.

AT&T packages

PackagePrice*SpeedInternet type
Fiber Internet 100$35.00/mo.100 MbpsFiber
Fiber Internet 300$45.00/mo.300 MbpsFiber
Internet 1000$60.00/mo.1,000 MbpsFiber
AT&T Fixed-Wireless Internet$59.99/mo.Approx. 25 MbpsFixed wireless

AT&T recently discontinued its DSL service, so for most customers, it’s all about the fiber. AT&T’s Internet 1000 plan impresses us because it has very fast speeds at a bargain price. The Internet 1000 plan also comes with a free subscription to HBO Max, AT&T’s flagship streaming service.

But you’ll probably be just as pleased with its Fiber Internet 100 or Fiber Internet 300 plans. Both also run over a fiber-optic network, delivering excellent performance—including impressive upload speeds of 100 Mbps or 300 Mbps, respectively. And they’re both really cheap, less expensive than even CenturyLink’s slower DSL plan.

CenturyLink is a solid pick if you want a good deal on fiber or DSL internet. CenturyLink’s DSL plans have Price for Life guarantees, so your price will never go up—a nice bit of relief considering that price hikes are often a feature of internet plans.

CenturyLink’s fiber gigabit plan also comes at a nice price. Although the baseline monthly fee isn’t quite as cheap as AT&T’s gigabit plan, CenturyLink’s offer comes with a router included and installation at no extra cost. You get unlimited data and you can cancel any time, since there are no contracts. Boo-yah!

Even if you have to rent a router, you can buy a CenturyLink modem/router up front, which will save you some dough in the long run compared to making monthly payments on a rental. Otherwise, its DSL modem costs $15 per month.

AT&T vs. CenturyLink: Which has the fastest internet speeds?

Internet speeds

AT&T and CenturyLink both have some of the fastest internet available to customers nationwide. Their fiber internet plans each deliver up to 940 Mbps download speeds, making them ideal for big families, gamers, binge-watching TV buffs, and work-from-homers who spend lots of time on Zoom.

AT&T’s fiber gigabit plan is slightly less expensive than CenturyLink’s to start—but after 12 months, AT&T’s gigabit plan goes up to $80 per month. So you’ll save money in the long run by sticking with CenturyLink’s fiber gigabit plan. But you may be more satisfied with AT&T, which has much better customer ratings than CenturyLink in our annual customer satisfaction survey. It gets some of the highest ratings for speed and reliability.

If you can’t get fiber from either of these providers, then they also have DSL internet plans. DSL is not known for speed, unfortunately—it tops out around 100 Mbps, and there’s no guarantee you can even get DSL that fast where you live.

DSL is a bit like having a Ford Fiesta instead of a Ferrari. It can still get you decent speeds, just not those eye-popping Ferrari speeds. Anywhere from 50–100 Mbps will still be plenty fast for a modestly sized household with several people all using multiple devices.

Internet types

AT&T and CenturyLink offer two types of internet—DSL and fiber.

Fiber internet is the best type of internet you can get, hands down. It’s the fastest, the most reliable—and also (*drum roll*) the rarest. Fiber is available in only select locations where ISPs have invested in building extremely costly fiber infrastructure.

If you can get fiber Wi-Fi from either of these providers, then you definitely should go for it. You’ll be getting the fastest speeds on the best type of internet infrastructure.

DSL is a bit of an ugly duckling among internet types. It waddles along through your old-school copper phone lines at speeds below 100 Mbps. But DSL plans also cost less and still give you a quality connection and decent speeds.

Fixed-wireless internet is mostly useful for rural customers who can’t get anything else in their area except for satellite internet. It’s relatively fast but AT&T’s fixed-wireless plan has a strict data cap of just 350 GB per month, with extra fees if you go over.

Do CenturyLink or AT&T offer bundles?

CenturyLink offers bundle package with internet and landline phone, but it has no bundles with TV packages. AT&T no longer offers bundle deals.

You used to be able to get bundles from AT&T that combined internet service with DIRECTV or AT&T TV, but those deals are no longer available. You can still order a TV package from DIRECTV or DIRECTV STREAM (the company’s new streaming-based service) but it costs the same price whether you combine it with internet or not.

AT&T vs. CenturyLink fees and contracts

Here’s the thing with internet plans: whether you choose AT&T or CenturyLink (or any other ISP), the monthly sticker price is not the whole price. Like a spring-loaded jack-in-the-box toy, your bill will also be popping with installation costs, taxes, and other fees.

We went ahead and collected all those fees and put them into a table right here. This is for your education and for the betterment of a transparent society.

AT&T fees

Modem rental$10
Installation$35 (self-install) or $99 (professional install)
Late feesUp to $10
Data overages$10 per 50 GB (fixed-wireless plans only)
TaxesCost may vary

To get your AT&T Internet up and ready, you can choose between doing self-installation or having a professional technician set it up. If you decide to install it yourself, you’ll need to fork over $35 for an “activation fee.” For a pro to do it, you’ll pay $99. The choice is yours.

CenturyLink fees

Modem rental$15/mo. (or $150 flat fee)
Installation$99 (free for self-installation)
Secure Wi-Fi service$5/mo. (optional)
Declined payment$10–$25
Late fees$15
TaxesCost may vary

When it comes to installation, getting Wi-Fi set up in your humble abode will cost a $99 flat fee if you require the services of a professional technician. If you’re fit to install it yourself, CenturyLink will mail you a self-install kit free of charge.

Pro tip:

Make sure to check with CenturyLink to see if you can self-install in your area. We’ve heard of some cases in which a technician was required to make adjustments to a customer’s plan.

Read our guides to CenturyLink installation and AT&T installation for more information on the differences between setting up your home network yourself and having a pro do it.

Internet contracts

AT&T and CenturyLink both do not require annual commitments for their internet plans. Their services run month to month, so you can cancel without having to pay a dreaded early termination fee (ETF).

CenturyLink goes one step further by putting Price for Life guarantees on all of its DSL plans, so you won’t ever see price hikes on your internet bill. That’s what we call a slam dunk.

AT&T’s internet plans have a fixed price for 12 months. After that, you will see the price go up on your bill.

Our take:

CenturyLink and AT&T both deserve props here for not requiring annual commitments from internet customers.

AT&T vs. CenturyLink equipment

Renting a modem and router

We think renting the equipment directly from the ISPs is a mighty fine option because it means you’re getting something that’s compatible with the company’s system and easy to troubleshoot or replace.

Buying a modem and router

Buying a modem and router can be good if you’re more of a tech expert and want better options to do things like online gaming, link aggregation, or setting up a guest network. Your own router can also come in handy if you want a long-range router to patch up Wi-Fi dead zones.

CenturyLink also lets you buy its router up front rather than rent it month-by-month. If you ask us, that really is the best option because then you’re saving cash and can keep it long-term.

In the long run, you’ll save money by buying your own modem and router. Just make sure that your equipment is compatible with the internet provider’s network.

AT&T vs. CenturyLink customer service

AT&T gets average rankings for customer service—it comes in fifth place among 12 major ISPs in our annual customer satisfaction survey. On the other hand, CenturyLink gets low rankings, coming in second to last place.

Installation fee: $35 or $99

Installation type:Pro and self-install

Schedule an installation

AT&T will hit you with a $35 activation fee if you choose to install your Wi-Fi yourself; otherwise, you’ll have to put down $99 to have a professional do it. CenturyLink will mail you a self-installation kit at no charge—but setting up your own internet isn’t necessarily a walk in the park.

If you’re a handy person in general, the self-installation process will be fairly straightforward. It’s usually just a matter of plugging power cords and Ethernet cables in to to the proper equipment and then doing some minor troubleshooting to make sure everything is turned on and working properly. It shouldn’t take longer than a couple hours as long as there aren’t any technical issues and everything necessary came with your self-install kit.

Customer satisfaction


Overall customer satisfaction rating:



Overall customer satisfaction rating:


AT&T gets top results when it comes to customer rankings. It gets second place for overall performance in our annual customer satisfaction survey, sitting pretty high on a list of 12 major internet providers. It also gets above-average ratings for speed and reliability.

CenturyLink comes in second to last place for overall satisfaction in our survey, likely because of the limitations inherent in the provider’s relatively slow DSL service. However, CenturyLink’s fiber customers are generally a lot more pleased with their service—the fiber customers we surveyed gave CenturyLink a much higher, 3.7 rating for speed and reliability.

Pros and cons


  • Unbeatable fiber gigabit price
  • Solid customer ratings
  • Great bundle options for cord-cutters


  • Annoying activation fee for self-installation
  • Limited fiber availability
  • Inconsistent DSL speeds


  • Guaranteed Price for Life on DSL
  • Free router with fiber internet
  • No cost for self-installation


  • Poor customer ratings
  • Limited fiber availability
  • Slow DSL in some areas

Our verdict: Pick AT&T for a great deal on fiber internet.

We think AT&T is the best out of these two juggernaut ISPs because it has fast, reliable internet for the best price.

With CenturyLink, you’ll get great speeds (most of the time) at a cheap price. You can get free self-installation and a free modem with the fiber gigabit plan. But if you’re getting DSL, make sure you can get adequate DSL speeds in your area. If the only speeds available are below 25 Mbps, don’t waste your mun-muns.

In the end, though, AT&T is the obvious pick out of these two. AT&T has great customer ratings and affordable prices. If you can get its fiber gigabit internet plan in your area, then you should definitely go for it because it’s a great deal for some of the speediest internet around. But watch out because the price will go up after the initial, 12-month promotion period.

AT&T vs. CenturyLink FAQ

What is AT&T U-verse?

AT&T U-verse used to be AT&T’s fiber TV service, but it’s no longer available to customers. If you’re looking for an AT&T bundle package with a cable-style TV option, then you can get it with DIRECTV or with AT&T TV, the company’s new streaming service.

Why is my AT&T internet so slow?

You may be experiencing an internet slowdown as web traffic across the country spikes now that millions more Americans than usual are working from home. If you find this problem persisting, consider upgrading your internet plan or budgeting your Wi-Fi usage. For example, you can put less strain on bandwidth by reducing the number of devices people are using simultaneously in your household.

Is CenturyLink internet good?

CenturyLink offers great internet over both DSL and fiber networks. Its gigabit internet plan delivers 1,000 Mbps speeds at a very reasonable price over a coveted fiber network. Its DSL plans are slower but less expensive, and that’s ideal if you’re on a budget or don’t use Wi-Fi for advanced purposes.

Is AT&T good?

AT&T delivers good, solid internet over DSL and fiber cables. Its fiber option is lightning fast and affordable. Its DSL option isn’t so fast but will get the job done and save you some money.

Do CenturyLink or AT&T have data caps?

CenturyLink and AT&T have both suspended their data caps in recent weeks due to the ongoing economic impact of the new coronavirus pandemic. The changes are in effect with both providers until mid-May, and during that time you’ll get unlimited data on any of their internet plans. Start downloading all those 50 GB video games while you still can.

Which is better: CenturyLink or AT&T?

We think CenturyLink’s internet is a better choice because it’s more affordable, with Price for Life deals on all DSL plans and free self-installation. But AT&T is also a great option because it has great customer service ratings and a very affordable fiber gigabit plan.
