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.

Pay more for a better customer experience with EarthLink

EarthLink is an interesting provider. Instead of serving internet through its own infrastructure, it partners with other internet providers to repackage their service, acting as a go-between. This means higher prices, but a reputation for great customer service might make EarthLink worth it.

What we like

  • Wide availability
  • Strong customer service
  • No price hikes
What we dislike

  • High prices
  • Widely differing plans based on area

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

Value

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.

4.0
Above-average prices, but they’re more constant than other providers

There’s no getting around it: EarthLink prices are almost always higher than the competition. Depending on the area, the difference can be as little as a few dollars per month, but it’s still there. That said, there are actually legitimate reasons for this.

First, EarthLink doesn’t actually have its own internet infrastructure. Instead, it partners with other local DSL and fiber internet providers, like AT&T and Frontier, and uses their infrastructure. This costs EarthLink money, and some of this naturally gets passed down to customers. In return, you’re promised a better customer experience.

The other reason is that EarthLink skips the usual promotional pricing most ISPs advertise. For example, when AT&T or Spectrum quote you a price, it’s often for an introductory period of 12 or 24 months, after which that price may increase (sometimes dramatically). EarthLink doesn’t do this, which is a plus in our book. This also means EarthLink may end up slightly less expensive if you intend to keep it for a couple of years.

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.

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

Performance
4.0
Generally solid performance and fast speeds, but wide variation from place to place

EarthLink's performance is tough to rate. Because it is essentially reselling other providers’ services, the speed and reliability are highly dependent on which partners it uses in a given area.

That said, performance is generally good, and there are a wide range of high-speed internet plans available in most areas, so you can get exactly how much you need—up to 5 gigs in some places. Much of the service is fiber, which means performance is reliably consistent. Best of all, every plan has unlimited data, so whatever speed you opt for, you can use it without worry.

Performance
4.0
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.

Available speeds vary by location. Call 1-844-716-2788 to speak with a Mediacom rep or

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
2.5
Reasonable prices, but wide variation from place to place (again)

This is another category that’s tough to rate. Since EarthLink partners with other internet service providers (ISPs) to provide service, it doesn’t actually issue its own equipment. Instead, you’ll get equipment from whichever partner EarthLink uses in your area. The good news is that EarthLink does set the fees, and they’re reasonable: $9.95 per month.

It’s a similar story for installation—your service will be installed and set up by a rep from the partner company, not EarthLink itself. The installation fee is $79.95, which isn’t the highest we’ve seen. That said, we’d rather see installation included in the price, particularly since EarthLink’s overall prices tend to be on the high side. Self-install is available only in some service areas.

Equipment and installation
3.0
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.

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
4.5
EarthLink provides a surprisingly great experience from an ISP.

Customer service is where EarthLink really shines. The company claims to prioritize customer service and experience, and users seem to agree. The company actually ranks first in some user-driven surveys of internet satisfaction, beating out providers like AT&T and Verizon despite the higher prices.

From a practical standpoint, it seems that EarthLink representatives are friendlier, more helpful, and more knowledgeable than those we’ve dealt with at other companies. However, we've seen reports that some customers don't get the Earthlink customer experience. In some places, customer service is handled by the end provider instead.

Customer experience
2.5
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.
