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
Savings tip: CenturyLink often has sign-up promotions for first-time customers. Call to ask a rep about current deals and discounts.

What we like

  • High-speed, reliable rural internet
  • Low cost
  • No contract
What we dislike

Lightning-fast, reliable internet at an excellent price

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
  • Excellent pricing
What we dislike

  • Data caps on some plans
  • Some billing complaints

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.

Uncommonly high speeds and low costs for rural internet

Smithville Communications offers just one fiber internet plan, serving up 1 Gbps and unlimited data for less than about $0.70 per Mbps. Compared to the US benchmark plan for similar service ($134.62) (1), Smithville is a pretty sweet deal. And you won’t have to sign a contract to get it.

This low price is particularly impressive for fiber in rural areas since building infrastructure outside of urban centers can be incredibly costly. Smithville could easily charge higher rates for bringing fiber to rural Indiana, but it doesn’t. And we applaud that.

Fast internet speeds at a great price

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. Eligible households may qualify for high-speed internet as low as $9.95 a month with unlimited data and equipment.

Depending on your area, you can get a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month. Those plans have a data cap of 1.2 terabytes which is a high data cap. Data caps are common among cable internet service providers (ISPs). Removing it costs an extra $30. But overall, this pricing is an excellent deal for the speeds you're getting.

The 400 Mbps plan, which is about right for an average family that's online a lot, 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 internet plans are available from Xfinity. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. For reference, 6 Mbps is ridiculously fast, and it also comes at a higher price. Most households don’t need 6 Gbps internet speeds unless they’re streaming a ton of 4K content or have several people gaming online at the same time. These fast internet plans do come with unlimited data, though, so it might still be worth it for some households.

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.

Available speeds vary by location. Call 1-833-804-2792 to speak with a CenturyLink rep or

Get 1 Gbps speeds and unlimited data—unless you’re in a legacy DSL area

Fiber is the fastest and most reliable type of internet available, and download speeds max out around 5 Gbps. Smithville fiber reaches only 1 Gbps, but for most people frustrated by slow or unreliable rural internet, it’ll feel like your browser just got a turbo boost. You’ll also see 1 Gbps upload speeds, which is less common among non-fiber internet types like DSL and cable. Everyone—from heavy streamers and online gamers to remote workers and avid YouTube creators—will have plenty of juice (and unlimited data) when they need it.

Unfortunately, there’s one caveat: In some areas, Smithville is still using legacy DSL infrastructure, so you might not be able to sign up for fiber just yet. Smithville is phasing out this infrastructure as it lays more fiber lines, and it was named one of the Top 100 Fiber-to-the-Home organizations by Broadband Communities magazine for its efforts in helping bring fiber internet to rural communities (2). Luckily, Smithville won’t lock you into a contract, so if you’re not happy with your DSL, you can cancel any time and come back later when you have access to fiber.

Some of the best internet reliability

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. Xfinity's internet 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
4.5
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.

Equipment and installation options can vary widely depending on

Free equipment, but you’ll have to pay for activation and possibly installation

Smithville provides a wireless router to all customers with no additional rental fees, which is a good deal. You will pay an activation fee of $25, and if you need any lines run or jacks installed, you’ll pay for those too.

You do have the option of using your own equipment, but you’ll have to contact customer service to find out if your gear is compatible because this info isn’t available on the Smithville website. And if you need help troubleshooting your equipment, you’re on your own.

Equipment and installation
4.0
DIY or professional install and Wi-Fi equipment

Xfinity internet offers the 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, but you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help, but beware that you 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 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.

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.

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.

Around-the-clock tech support—at a cost

Smithville offers 24/7 tech support to all customers, which is helpful if you have trouble with its router, need wiring repairs or a jack replacement, or your service is otherwise interrupted and it’s the company's fault.

If a visiting technician discovers the problem was out of Smithville’s control, you’ll have to pay a $35 service fee and $90 technician fee for help. Most companies charge you only one of these fees. Smithville will waive these charges if you buy its Connection Protection plan for at least one year, at a cost of $3.95 per month. But technicians still won’t help you with your own equipment.

Rapidly improving customer service scores

The Xfinity internet customer experience is 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 with Xfinity.

On the other hand, Xfinity internet has a spotty customer service track record. It ranks above average on customer surveys (4). While customer service seems to be above average, not everyone has a great experience, and we've seen some complaints about billing issues and miscommunication between the company and their technicians.

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.
