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.

Inconsistent speeds for the price, but it’ll do

This budget internet provider offers DSL, cable, and fiber internet at a low price. However, TDS doesn’t guarantee advertised speeds, and the quality of service will likely vary by location and connection type. If you want the highest speeds, guaranteed speeds, or unlimited data, this might not be the provider for you, but if you can get fiber, it’s worth a look.

What we like

  • Several plan options
  • Fiber in some areas
  • Easy installation
What we dislike

  • Complaints about speed
  • Self-setup not available everywhere
  • Contract required

Fast, reliable fiber for larger households and power users

Ziply offers great pricing for medium-to-large households and absurdly fast internet for power users. This provider has a few quirks, like hidden contracts and no self-setup, but if those don’t bother you, Ziply is a solid internet service provider in the Northwestern US.

What we like

  • Low prices
  • Fast internet
What we dislike

  • Hidden contracts with promotional pricing
  • No self-setup

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.

Low prices, but varying value

TDS’s DSL, cable, and fiber internet range from a superslow 1 Mbps to a superfast 2 Gbps, with over a dozen plans in between. Prices vary by location, but most seem to come in below US benchmarks for comparable broadband speeds (1) and are cheaper than similar plans from Xfinity, Spectrum, and Cox.

Our favorite things about TDS prices is that in some locations, we've seen a "price for life" guarantee. That means the price you sign up at is the same price you'll pay as long as you're a customer. Since most providers have significant price hikes after a year or two of service, being able to lock in your price is a huge deal—and a big reason to stick with instead of switching to a different internet company.

We interviewed Marci-Ray, a TDS fiber customer since 2020. In a household with multiple gaming consoles and smart home devices, she’s been very pleased with the reliability and price of the 300 Mbps fiber plan: “For the value of the speed and the price…it’s great. I’m very happy with that.”

Unfortunately, not all TDS customers have had the same experience. We’ve seen some customer complaints about slower-than-advertised speeds, meaning that customers aren’t getting what they paid for, especially on DSL or cable plans. If you opt for a higher plan to account for that (which is what TDS recommends if you don't see the speeds it advertises), you may end up paying more than you would somewhere else for the same speed.

Low-cost internet plans—unless you want the fastest speeds possible

Overall, Ziply offers fast fiber internet at great prices. Its slowest plans (50 Mbps and 200 Mbps) are the best value, priced at 25% and 33% of the national benchmark, respectively. (1) Its 1 gig plan is relatively more expensive, but it still comes in under 45% of the national benchmark for similar plans. After introductory pricing ends, your monthly bill will increase by about $20 per month, but you’ll still pay less than average. Plus, you’ll get unlimited data.

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

Speeds not guaranteed

TDS says you could see speeds “up to” your plan’s max, which isn’t uncommon of internet service providers, but TDS seems to get a lot of complaints from customers seeing much lower speeds than advertised. And if you’re not happy with the speeds you’re seeing, TDS’ solution is to switch to a lower-level plan, and it’ll waive its usual $15 fee for switching plans mid-contract. But if you ask us, this feels like an ineffective solution since lower-level plan speeds aren’t guaranteed either. You could end up with even lower speeds, albeit at a lower cost.

If TDS fiber is available in your area, you should see more consistent speeds since fiber-optic technology is more reliable all around. One customer who switched from Spectrum cable service to TDS fiber in the Madison, WI area told us that TDS has been far more reliable for them, with fewer slowdowns and outages.

Depending on your location, your TDS plan might come with unlimited data. Or it might come with a data cap of 500 GB and overage fees if you go over that. This cap is pretty low, considering most people use around 500 GB per month all on their own. Unless you live alone, it won’t be enough. And if you use less than 500 GB, the extra won’t roll over.

Available speeds vary by location. Call 1-844-726-0721 to speak with a TDS Telecom rep or

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.

Low-cost equipment and installation options

TDS offers two equipment options, which you purchase and pay down each month. A standard modem and Wi-Fi router combo is $10/month, and Wi-Fi+ is around $20/month. Wi-Fi+ comes with a modem plus an eero Wi-Fi home base and one mesh extender—all of which should give you 2,500 sq. ft. of signal, which isn’t too bad. (2) TDS recommends adding an extender ($5) for every additional 1,000 feet beyond that. This system comes with a smartphone app that makes managing your Wi-Fi easy.

Self-installation is free and takes about 15 minutes, but it’s available in only some locations. In others, professional installation is required for no additional charge. However, if self-installation is available in your area and you still want professional help, it’ll cost you around $50.

Equipment and installation costs mostly balance each other out

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.

Extra help if you need it—at a price

Like most internet service providers, TDS gets mixed reviews from customers, but overall it seems about average. You’ll get around-the-clock tech support, including phone calls, online chat, and remote internet sessions (during which a technician logs into your computer remotely to troubleshoot your connection).

If you want help with more than your connection, you can pay around $13 per month for a Remote PC Support subscription. With it, you can get help with network security, optimizing your computer, and setting up your devices. Without the subscription, you’ll pay around $50 each time you need these services. If you’re tech savvy, you’ll save a lot by skipping the subscription. But if you think you’ll need help at least once per quarter, the subscription will be cheaper.

When we interviewed a current customer about their experience with TDS customer support, they said that TDS was very responsive, clearly explained what was happening, and fixed connection issues for them without charging for the service.

They were also able to negotiate their internet price back down after their promotional price ended. TDS customer service recommended setting a calendar reminder to call in again each time the promo pricing was close to running out. It’s less convenient than just getting the lower price consistently, but we appreciate the willingness to bring prices back down.

The one downside the customer mentioned was the lack of a dedicated app for managing their service and billing—something many other providers already provide.

Could be more customer-friendly with more self-help options and better transparency

We love that Ziply provides professional installation for free, but we’re bummed that it doesn’t even offer a self-setup option. Ziply has some great self-help content on its website for troubleshooting or changing out your router later—you just can’t use it to get started. Forcing you to use professional installation also means it takes longer to get started, and that’s tough if you’ve just moved to the area. If you’re not moving, it still means you’ll have to juggle your old service with Ziply installation times to avoid a gap in internet service.

We’re also not a fan of Ziply’s hidden contracts. It advertises no-contract plans, 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, and most negative reviews call out the same kinds of issues other providers get: billing disputes. (4)
