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

  • Simple plan selection
  • No contracts
  • No data cap
What we dislike

  • Pricey gig plan
  • Lots of small fees
  • Price increase after 12 months

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

  • Pricing stipulations
  • Price increase after 12 months

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.

Straightforward internet plans with budget-friendly pricing

Spectrum service offers a solid value—particularly at the lowest tier. There are only three plans to choose from, which could either be a plus or minus depending on your perspective. In this case, we feel it’s a good thing: the plans are straightforward and easy to understand.

The lowest-tier plan offers speeds up to 300 Mbps (wireless speeds may vary) at a decent price, according to government benchmarks (1). That's just $0.17 per megabit per second, with speeds that blow any DSL plan out of the water. The other two internet plans are less exciting, but still reasonably priced for the first year. After 12 months, your price could be up by $20 or more.

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

Performance
4.0
Reliable internet with speeds up to 1 Gbps

Spectrum offers speedy performance overall, with packages up to 1,000 Mbps available (wireless speeds may vary). The lower tiers are more exciting—almost every provider has a gig plan these days, but Spectrum’s lowest plan has speeds up to 300 Mbps, which is still excellent for all but the heaviest users. Additionally, there are no data caps on any of the plans, so you can use as much bandwidth as you like.

Speed is only half the equation, though—even the fastest connection is useless if it doesn’t work when you need it. Luckily, Spectrum is on par with its closest cable competitors here. It offers faster-than-advertised speeds most of the time, according to the US Federal Communications Commission (2), and earned the top spot for median speeds from Speedtest.net (3). Spectrum’s latency scores were a little higher than competitors Xfinity and Cox, but at just 25 ms, you’re still within the playability range for most online games.

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.

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
4.5
You can rent a router or use your own, and there’s a fee for self-installation

Spectrum’s equipment setup is a bit different than most—at least when it comes to fees. There is no charge for the modem, but there is a $5 monthly fee for the wireless router (waived on the gig plan). What this means is that Spectrum gives you a separate modem and router, instead of a combined gateway. It also means you can opt to bring your own wireless router if you prefer. Customers can also add Wi-Fi extenders, called Pods, for $3 each per month. If you use the Spectrum router, you can use the company's highly rated smartphone app to manage settings and parental controls.

Installation is straightforward and affordable. If you need a pro to come out, you can opt for a professional installation for $59.99. If you can handle the installation yourself, the self-install kit is about $25. We’d prefer free self-installation, but it isn’t the highest self-install fee we’ve seen, so we’ll take what we can get.

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.

Customer Experience

Watch out for hefty fees and price hikes down the road

We’ll just come right out and say it: Spectrum has a lot of fees. While you may never see most of them, it’s worth noting that they’re there. Here’s a sample:

  • $5 to pay over the phone(?!)
  • $5 reconnection fee
  • $19.99 to upgrade equipment when switching to the Internet Gig plan

These aren’t going to be on every bill, and you may never see most of them. However, when you do, it makes for a poor experience.

When you add second-year price hikes in the range of $20+, things aren't looking good for Spectrum customers. However, Spectrum customers seem to be about as satisfied with customer service as customers with competitors Cox and CenturyLink, and it's only slightly worse than average. (4)

If Spectrum is the only cable provider in your area and your home isn't wired for fiber internet, we recommend the service. Just set a calendar reminder to contact customer service in a year and see if you can negotiate the price down!

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)
