Some of the best value for fiber internet

AT&T offers one of the best values in internet service—fast fiber internet speeds at reasonable prices, plus some of the best support in the business and rock-solid reliability. With no contracts, no data caps, and no monthly equipment fee, AT&T is one of the best home internet providers we tested.

What we like

  • Competitive fiber plans
  • Solid customer support
  • Excellent reliability
What we dislike

  • Expensive installation fees
  • Higher monthly prices than some competitors
  • Few TV bundling options
Savings tip: AT&T often has sign-up promotions for first-time customers. Call to ask a rep about current deals and discounts.

Great fiber service, if you can get it

CenturyLink offers excellent fiber internet, but it’s available only in limited markets. If you can't get fiber, you may be able to get a DSL connection but you'll pay nearly as much.

What we like

  • Unlimited data across all plans
  • Fast fiber connections in select markets
  • No contracts
What we dislike

  • Limited fiber availability
  • Much slower DSL internet speeds
  • Below-average customer service

Hyper-gig download speeds and improving customer service

Xfinity is a fantastic provider overall. It offers fast speeds, reliable service, and reasonable prices. Some plans still require contracts, and others still have data limits. Watch out for Xfinity’s hidden fees and spotty customer service record, but it may not be as bad as it once was.

What we like

  • Consistently fast speeds
  • Wide availability around the country
  • Competitive pricing, especially for budget plans
What we dislike

  • Data caps on slower plans (unless you pay more)
  • Inconsistent pricing and speed availability
  • Reputation for poor customer service

Fiber internet is a great deal

The AT&T fiber plans represent an excellent value proposition. The speeds are competitive, and the prices at any given tier are lower than nearly every other provider. One exception, Xfinity, offers slightly cheaper gig plans in some markets. Another, Google Fiber, offers $10 less on gigabit speeds. However, AT&T is more likely to be available in areas that have cable internet from Spectrum and Cox, and we think AT&T fiber is usually the better deal.

For the money with AT&T, you get outstanding download speeds and excellent upload speeds. And with unlimited data on fiber internet plans, you can actually use your gigabit connection without worry.

Some legacy customers may have DSL internet from AT&T. The most affordable AT&T plan is more than $50 per month, but this can either be basic DSL (speeds up to 75 Mbps) or the excellent, fiber-based Internet 300. If you can get only AT&T fixed wireless, you’ll pay higher prices, face data caps, and suffer through 1 Mbps upload speeds. Other providers just offer much better deals on plans in these tiers.

Great fiber value meets high-cost, low-performance DSL plans

CenturyLink offers two types of plans, depending on your location. The more common option is DSL, which is relatively slow and offers inconsistent speeds. The other option is fiber, which is extremely fast and reliable.

Generally speaking, the DSL options are not a great value. The price is reasonable, but the speeds mean you’re likely to get more for your money elsewhere (this is true for many DSL providers). The fiber plans are a much better value—they offer much more speed for the money than CenturyLink’s DSL plans and are competitive with other providers’ fiber offerings. In fact, CenturyLink's 940 Mbps plan costs a little more than half of the national benchmark for similar plans. (1) We highly recommend CenturyLink fiber if you have it available.

Budget broadband internet plans are a great deal

Xfinity is generally a very good value, especially at the middle and lower tiers. In fact, it offers some of the best budget plans of any of the major internet service providers, with a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month in some areas. Those plans have a data cap of 1.2 terabytes per month, which is disappointing but common among cable internet service providers (ISPs). Removing it costs an extra $30.

The 400 Mbps plan, which is about right for an average family, is also a great price. It rings in at about 36% of the national benchmark in its range. (1) That means you're paying just $0.18 per megabit, with plenty of megabits to go around.

Faster plans are available, but they are pretty pricey compared to the best fiber internet competitors we reviewed. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. That is ludicrously fast, but it’s also really expensive. Most households don’t need those internet speeds unless they’re streaming a ton of 4K content at the same time or have 10 or more users, so we don’t recommend them for most households. They do come with unlimited data, though, so might still be worth it for some households.

Fast, reliable speeds any time of day

AT&T claims 99% reliability (1) for its fiber internet service, and that’s pretty accurate in our experience. In fact, over several years of constant daily use in a packed house (two people working from home, two kids doing schoolwork, lots of streaming video and calls), we haven’t had a single major disruption. This is a marked contrast to our previous provider.

Additionally, speeds are consistent, with little variation based on the time of day, activity, or even the particular speed test used. Its median download speeds are slightly slower than its cable and fiber internet competitors, but only by a matter of milliseconds (2). This all adds up to a great experience where the service “just works,” and nobody ever really needs to wonder if they’ll be able to do what they need to do.

It's also worth mentioning that because AT&T fiber internet uses fiber-optic cables, upload speeds are equal to download speeds. That means you can upload huge files in seconds, video chat, live stream game play, and more without a hiccup.

Available speeds vary by location. Call 1-833-804-1770 to speak with a AT&T rep or

Performance is excellent for areas with fiber access

There’s a performance divide based on the type of service available. The CenturyLink DSL plans can range from 15 to 100 Mbps, which is a wide range. Additionally, 15 Mbps just isn’t great these days. It doesn’t even reach broadband speeds (25 Mbps or more). That said, you shouldn’t have to worry about getting the advertised speed—whatever plan you sign up for, you seem to get what you pay for with CenturyLink.

On the other hand, the fiber plans offer Gigabit speeds (up to 940 Mbps), which is excellent. Additionally, fiber internet offers synchronous download speeds and upload speeds, meaning you can game, video chat, or upload large files just as fast as you binge Netflix. Fiber also tends to be inherently reliable because of the way the technology works—the light signals in fiber optic cables can carry more information over longer distances than coaxial cables. We have no complaints about performance on these plans.

Some of the best internet reliability we found

Xfinity internet performance is excellent. Its speeds are fast and reliable. In fact, in many markets, it has one of the fastest internet speeds around. The service is reliable and consistent. If outages occur, Xfinity is responsive and generally restores service within hours. Xfinity internet is also highly rated for speed (2), and research from the US Federal Communication Commission (FCC) scored it among the top for reliability (3).

Equipment and installation
4.0
Free equipment and free self-installs for fiber internet

AT&T fiber internet installation is about as simple as it gets. You have two options: a $99 professional installation by an AT&T technician or a DIY self-install kit.

If you can get only DSL with AT&T, the equipment is still free but you'll be charged a $49 activation fee. If you don't want to self-install, you can have a pro come out for an additional $99.

The self-install is very easy and comes with clear instructions, so we’d recommend that for pretty much everyone. Activation and configuration of your Wi-Fi network are handled through the simple AT&T Smart Home Manager app, so you don’t even need to log into the router settings page like with some other providers.

It is worth noting that both of these charges are a bit higher than what the competition charges. CenturyLink doesn’t charge for self-installation, for example, while Xfinity charges only $89.99 for a professional install.

That said, if you do need a professional to come out, you can count on fast and friendly service. We’ve personally had techs out on a couple of occasions and were happy with the experience.

Learn more about whether you need a professional installation.

Finally, the AT&T wireless gateway is surprisingly nice. Called AT&T Smart Wi-Fi, it’s super simple to set up, provides solid range, and looks decent on a desk. Compared to the routers and gateways provided by some other providers, this one’s a breath of fresh air.

Equipment and installation
4.5
A fee for self-installation, but good equipment at a decent price

CenturyLink installation is more or less on par with other providers in terms of installation procedures and costs. If your neighborhood is wired for only DSL with CenturyLink, you can have your internet service set up by a pro for somewhere between $129 and $300 based on the installation requirements. You can alternatively choose to do a self-install for $15.

If you live in an area wired for CenturyLink fiber, your pro installation and equipment rental are free, and you may be able to self-install for free. You could also wrangle unlimited data and an included mesh wireless network if you sign a contract, so be sure to ask. This is about on par with other fiber internet providers.

Find out whether you need a professional to come by or if you can handle setup yourself.

As for equipment, the CenturyLink modem and router are also pretty standard stuff. The company charges around $15 per month for equipment rentals for DSL customers. The gear is nothing to write home about, but it works. You can also buy the modem outright from CenturyLink for up to $200—whether this is a good deal for you depends on how long you plan to have CenturyLink as a provider.

We don’t particularly recommend buying your own router. Both the DSL and fiber services require a modem certified by CenturyLink to function, so you may as well save some money and use the built-in wireless router.

Typical installation fees and Wi-Fi equipment

Xfinity internet offers the usual choice of professional and self-installation. The professional option is often more affordable than competitors, at $100. It's required if you haven't had Xfinity service at the address for more than 12 months. The self-install kit is free, though you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help but may face long hold times.

As for equipment, the Xfinity xFi gateway is fairly typical (and costs a fairly typical $14 per month). You can also add a Wi-Fi extender (and unlimited data) if you bump up to xFi Complete for about $15 per month for the first two years (and $25 per month starting in year 3). This is a bit steep for just the extender—you can grab an excellent Wi-Fi extender for right around $50. However, using Xfinity's equipment gives you unlimited data, and you qualify for a free upgrade after three years.

Read more about how internet bills work.

If you use your own equipment, unlimited data costs an extra $30 per month for lower tier plans, but is included for plans of at least 1 Gbps.

Better customer service, with more options

Internet providers have traditionally had a terrible reputation for customer service, but AT&T scores above average with national rating organizations like the American Customer Satisfaction Index (ACSI). These ratings have improved over the last few years, which is encouraging.

AT&T offers several options for getting help:

The support site also has lots of information available. It’s easy to use, and if you do need more help, the options involving service reps usually get a quick, friendly response. While it’s not perfect 100% of the time, AT&T customer support tends to be better than average.

AT&T makes it easy to stay connected away from home, too. Subscribers get access to a nationwide network of free Wi-Fi hotspots. Since AT&T offers mobile phone service in addition to internet, you'll be able to log on in from almost anywhere.

Customer experience

Below-average customer service

CenturyLink consistently scores slightly below average in customer satisfaction (2), largely due to complaints about a lack of responsiveness regarding customer service. The service also gets a lot of complaints from new fiber internet customers, but complaints are very common industry-wide.

CenturyLink hires techs and contractors from around the country, so some inconsistency is expected. It redeems itself slightly, though, with an easy-to-use support page.

The company is expanding and we hear that many new cities will have fiber internet hookups from CenturyLink within the next few years. If you can get only DSL, though, you may have a connection as slow as 3 Mbps or one as fast as 100 Mbps, with huge variation in latency depending on how far you are from the nearest access point.

We like that CenturyLink provides DSL to customers who may have no other option, but we don't recommend the DSL offering if you have access to cable or fiber internet from another provider.

Rapidly improving customer service scores

The Xfinity internet customer experience is kind of a mixed bag. On the one hand, you have reliable service, with the option for unlimited data if you want it. This makes for a great day-to-day experience.

On the other hand, Xfinity internet has a spotty customer service track record. Technically, it ranks above average on customer surveys (4). That said, we all remember the memes from a few years ago. While customer service seems to be improving (based on survey scores, at least), not everyone has a great experience, and we still see a lot of complaints about billing issues and miscommunication between the company and the techs it hires.

If you need to connect with the company, we recommend using its customer service portal and downloading the Xfinity app first before trying to reach reps by phone.
