Incredible price for fast fiber internet

We're big fans of AT&T fiber internet for its fast speeds, reasonable prices, and great customer service. AT&T offers fantastic value: fast fiber internet speeds at reasonable prices, plus some of the best customer 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.

What we like

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

  • Expensive installation fees
  • 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

Reliable, fast internet, but watch for fees

Mediacom offers a decent overall experience, with fast speeds and modern Wi-Fi gear. However, big rate hikes, a hefty installation cost, and lots of small fees bring the rating down.

What we like

  • Nice selection of plans
  • Very low initial prices
  • Solid availability
What we dislike

  • Contract required
  • Regular price increases
  • No unlimited data option

Fiber internet is an excellent deal

The AT&T fiber internet plans represent give you serious value for your money. 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 on speeds being throttled after you're over a data allotment.

Some legacy AT&T customers may have DSL internet from AT&T. The most affordable AT&T plan is about $50 per month, and this can either be basic DSL (speeds up to 75 Mbps) or the outstandding, fiber-based Internet 300. Availability of plans depends on your service area.

If you can get only AT&T fixed wireless, you may experience data caps and get 1 Mbps upload speeds. In this case, other internet providers might offer you better deals on DSL internet plans.

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.

Excellent initial value, but heavy price hikes hurt the rating

Rating Mediacom’s value requires a long-term mindset. When you first sign up, the prices are extremely low—possibly the best on the market. Some come in at just 20% of the national benchmark, if you opt for paperless billing and autopay (1). However, each year, your cost gradually increases until it reaches a “standard value” (usually after three years). These prices are less exciting: you’ll end up paying roughly double what you initially signed up for. Depending on the length of your contract term, you may be able to jump ship before the price gets too high, but this might be too much effort for some.

Now, to be fair, many internet service providers (ISPs) do this (with a few notable exceptions, like CenturyLink). Mediacom is also pretty transparent about these price hikes and when you can expect them. However, the low starting prices here make the increases feel worse than they are, and that’s not great.

Fast, reliable speeds any time of day

AT&T claims 99% reliability (1) for its fiber internet service, and that’s astoundingly 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 huge victory compared to experiences I've had with other internet providers.

When you have reliable internet from AT&T, you don't even think about it. All your internet-based needs are met, without any friction or worry. AT&T internet 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, which is hardly noticeable (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. With many other internet providers, the download speeds are much slower than the download speed, so this is a huge benefit.

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

Performance
4.5
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.

Solid performance, but no unlimited data is a bummer

We have no major complaints about Mediacom’s performance. There’s a range of plans available (up to 1 Gbps), so you can find something to suit whatever your needs are. We do have a couple of small gripes, though.

First, there are data caps on all internet plans, with no unlimited data option. The lowest-tier package has a cap of just 350 GB, which is pretty harsh, given the average person uses 536 GB per month (2). The middle-tier internet plans have 1.5 and 3 TB limits, and that's better—this should be plenty for most users and is in line with most other providers that have data caps.

The 1 Gbps plan bumps data caps up to 6 TB, which is effectively unlimited for most use cases, although a household streaming in 4K could theoretically max this one out, too. Going over the cap costs $10 per 50 GB, which, again, is in line with other providers charging overage fees.

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

It's very easy to install AT&T fiber internet. In fact, internet installation really doesn't get easier. You can choose between professional installation or self-install, which is really nice. Many other internet providers don't give you the option to choose your installation type yourself. You can choose a $99 professional installation by an AT&T technician or a DIY self-install kit.

If you can only get 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 and have them do everything for you.

If you're up for installing yourself, AT&T sends easy and clear instructions. 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's a really seamless DIY install experience.

If you prefer to have your AT&T internet installed for you, it's a breeze. You can count on fast and friendly service. I've personally interacted with in-person AT&T on a couple of occasions, and I was very happy with the experience. Professional installation is nice when you don't have the time, energy, or confidence to install internet yourself. You'll feel like you're getting the royal treatment as you sit back, relax, and have it done for you.

The AT&T wireless gateway is really nice. Called AT&T Smart Wi-Fi, it’s super simple to set up, provides solid range, and looks sleek 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.

CenturyLink plans

Equipment is excellent, but the installation fee is steep

Mediacom offers a home networking combo called Xtream WiFi360pro. It uses a cable modem and eero Pro 6 mesh routers to ensure coverage over your whole house. The cost is $10 per month for a pair of routers, and you can add additional units for $6 each if needed.

Installation is less exciting. A professional installation and an activation fee will cost you around $120 total, and there’s no option to do it yourself. The fees can sometimes be waived with certain promotions—we recommend shopping around for one or asking a sales rep because these are steep.

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
3.0
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.

Customer experience

Lots of fees add up to a so-so experience

The Mediacom customer experience is decent overall. The provider scores a bit below average on customer satisfaction surveys like the American Customer Satisfaction Index (ACSI) (3), but overall, the service itself is fine. Speeds are solid and reliable, the Wi-Fi equipment is good, and the prices are competitive (at least initially).

Our biggest knock against Mediacom is the tremendous amount of small fees the company hits you with. In addition to the equipment and installation fees already mentioned, the company charges one-time fees for activation, early termination of your contract, and “Wi-Fi certification” (whatever that means). There’s a fee every time you have a technician come out for service. All these fees add up and can really sour the experience over time.
