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.

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

Fast, reliable fiber for larger households and power users

Ziply offers impressively fast, reliable internet for medium to large households, power users, and businesses. Ziply's internet speeds go up to 50 gigs, which is way more than most internet providers! Ziply offers super low-cost introductory pricing for 12 months, and they include professional installation for free. Overall, Ziply is a trusted, transparent internet service provider in the Northwestern US.

What we like

  • Low introductory prices
  • Fast internet
  • Free professional install
What we dislike

  • Pricing stipulations
  • Price increase after 12 months

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.

Value
4.0
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.

Low-cost internet plans

Ziply offers fast fiber internet at great prices. You get an exceptionally low introductory price for 12 months. Plus, you get professional installation at no charge, which is about a $90 value.

Ziply's pricing and promotions depends on your location and service area. You get very low, promotional pricing for the first 12 months, and then prices increase after the introductory period. You can ask what the price increase may be after your introductory period, but Ziply says this estimate is subject to change.

Ziply's low promotional pricing for the first 12 months is contingent upon enrolling in autopay and paperless billing. Here's an estimate of Ziply's promotional pricing and increases in select areas:

  • Fiber 100/100: $20 a month for 12 months, then $45 a month
  • Fiber 300/300: $30 a month for 12 months, then $65 a month
  • Fiber Gig: $50 a month for 12 months, then $85 a month
  • Fiber 2 Gigs: $60 a month for 12 months, then $95 a month

Ziply's slowest internet plans (50 Mbps and 200 Mbps) are the best value, priced at 25% and 33% of the national benchmark, respectively for their introductory prices. (1) Its 1 gig plan is relatively more expensive, but its introductory price still comes in under 45% of the national benchmark for similar plans.

If you want the absolute fastest internet possible, Ziply also offers 2- and 5-gig plans, but these come with much higher price tags. A 2-gig plan is nearly double the cost of a 1-gig plan (no bulk discount here), and a 5-gig plan is nearly 4 times the cost! (2) And there’s no introductory pricing for these blazing-fast plans. You’ll also need to spring for your own router (the Ziply one doesn’t support these speeds). 1 gig should be more than enough speed to cover the vast majority of households, so we don’t recommend springing for these plans unless you’re sure you need them.

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

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

Ziply Fiber brand
Performance
5.0
Fast, reliable fiber in most areas

Ziply has a fiber optic network, which is the most reliable kind of infrastructure out there. Fiber also allows for faster speeds than any other kind of internet, including upload speeds that are just as fast as download speeds (AKA symmetrical speed). Unfortunately, Ziply’s 1-gig plan isn’t symmetrical, serving up only 35 Mbps for upload, and that’s a shame. Still, most families will find a symmetrical 200 Mbps connection plenty fast, while high-powered users can opt for a 2- or 5-gig symmetrical plan (though it’ll cost you big).

Other than that, Ziply performs pretty well. It typically uses only 40% of its infrastructure capacity (3), which means you’re less likely to see slowdowns during peak hours. However, Ziply has legacy DSL infrastructure in some rural areas and tends to perform slower than other DSL providers.

Available speeds vary by location. Call 1-833-970-0803 to speak with a Ziply Fiber 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 options can vary widely depending on
CenturyLink plans
available in your area.

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.

Equipment and installation
4.0
Free professional installation

Ziply’s equipment costs can add up. Its router/modem combo is a reasonable $10 per month, but its Whole Home Wi-Fi costs $20 per month. Sometimes, Ziply runs promotions that include Wi-Fi, so keep an eye out for those. Ziply’s Wi-Fi is Wi-Fi 6 technology, which is the best technology available. You can stream up to 12 devices at once (Wi-Fi 5 allows only up to 5). However, Ziply’s router isn’t compatible with its 2- and 5- gig plans. If you want one of these plans, you must BYO router, and not all routers are compatible, so be careful here.

Professional installation is free, which is great because Ziply doesn’t have a self-install option. Technicians will run cables from the street to your home, wire up your house, and set up your Whole Home Wi-Fi. The downside is technicians likely won’t get all this done in a single visit, so it might take a few weeks to get you up and running.

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.

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.

No contracts but early cancellation charges

Ziply has a good reputation for customer service. They offer free professional internet installation and no contracts, which are nice perks. Compared to competitors, Ziply prides itself on transparency.

Ziply provides excellent support. We love that Ziply provides professional installation for free, but we wish they offered a self-setup option, too. But it's nice that it's installed for you and it's one less thing you have to do yourself. Ziply has some great self-help content on its website for troubleshooting or changing out your router later if you'd like.

Ziply is really transparent about a lot of things related to their internet service. Ziply is clear that their promotional pricing is just for 12 months and it increases after that period. They're also transparent with the fact that you need to enroll in autopay and paperless billing to get promotional pricing.

One thing that's not clear in Ziply's language is that you may have to pay early termination charges if you cancel before 12 months of service. This can be a bit confusing because Ziply says it doesn't have contracts. But if you read the fine print, you’ll pay early termination charges if you try to leave before your promotional plan ends.

All that said, Ziply’s customer service is decent, people are overall happy with service, and most negative reviews call out the same kinds of issues other providers get: billing disputes. (4)
