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.

Low starting prices and reliable internet speeds

Cox provides a great customer experience and reliable speeds, but you’ll spend more for higher-speed plans, extra data, and add-ons.

What we like

  • Plan variety and options
  • Great customer experience
  • Generous, unthrottled data cap
What we dislike

  • Expensive plans

Excellent service, if you can get fiber

The story of Frontier internet is one of two services: a slow and expensive DSL network and a fast and affordable fiber network. Which one you get makes all the difference.

What we like

  • Well-priced fiber plans
  • Fast speeds
  • No data caps
What we dislike

  • Limited fiber availability
  • Slow DSL in non-fiber areas
  • Poor customer service reputation

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.

Cox
Value
3.0
Good budget plans, but you’ll pay high prices for top speeds

Cox plans range from around $0.60/Mbps for low-speed plans to around $0.10/Mbps for the fastest plan, which is more expensive than other cable internet providers. The good news? Cox has more lower-speed plan options, so if your internet budget tops out at $50 a month, Cox might be your new best friend. At speeds of 200 Mbps and above, however, Cox loses the price war.

What you get for the money is pretty good. All plans have a 1.25 TB data cap (unless you pay an extra $50 per month for unlimited), but that’s more than most people need. And unlike providers where unlimited comes standard, Cox won’t throttle your speed if you get a little data-hungry. Just beware of overage charges (which can really add up) if you go over the limit.

Frontier offers excellent value on its fiber plans—if you can get them

Frontier offers two types of internet service: fiber and DSL. That means there are two sides to the Frontier value equation. Frontier fiber service is generally an excellent value—you can get 500 Mbps for around $50 per month or 1 gig for around $75, both of which are excellent prices well below the national benchmark for similar plans. (1) If you go for 2 gigs or even the newly available 5 gig plan, you'll pay quite a bit every month but enjoy excellent reliability and super fast speeds. If you go for 5 gigs, free tech support is included.

On the other hand, Frontier’s DSL plan is not nearly so exciting. It is around $50 per month for up to 115 Mbps, but the actual speed varies heavily with the specific area you’re in. Many places won’t see anywhere near 115 Mbps, but even if you do have that speed available, it’s not great for the price. There's also a required $85 installation charge. The good news, though, is that Frontier guarantees its DSL pricing for two years and doesn't require you to sign a contract.

To be fair, DSL service is almost always a poor value for money—it’s not unique to Frontier. And unlike some other combined fiber and internet providers, Frontier offers fiber in a good portion of its coverage area. (4)

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

Speeds are very reliable, but expect minor slowdowns at peak times

Generally, Cox delivers the speeds it says it does, sometimes even a bit higher—though the speed you experience also depends on lots of factors, such as the equipment you’re using and your distance from the router.

Cox specializes in cable internet, which is faster than DSL and satellite, but slower and less reliable than fiber. It’s also typically cheaper and more reliable than wireless internet. The US Federal Communication Commission, in fact, says actual speeds from Cox are faster than advertised and nearly identical to competitor Optimum. Those speeds are stable, too. The report found slowdowns less than 5% of the time. (1) However, cable internet is known to be slower during peak usage times because you and your neighbors are all using the same street lines.

Available speeds vary by location. Call 1-844-719-0028 to speak with a Cox rep or

Performance
5.0
Outstanding fiber performance and so-so DSL service

Frontier continues the tale of two in the performance department. The DSL service caps out at a fairly slow 115 Mbps, and that’s only in certain areas. While that’s sufficient for many day-to-day activities and light streaming, larger families or those who want to stream in HD may be left wanting more.

On the flip side, the fiber service is predictably excellent, with speeds up to 2,000 Mbps and no data caps to limit you. In fact, Frontier's fiber plans are some of the fastest, according to PCMag (2). The service has the fastest ping of any provider, according and a study by the FCC (3), and it's neck and neck with the competition in terms of speed and reliability. These fiber plans also offer symmetrical speeds, which means the upload speed is equal to the download speed. This is handy if you upload or share a lot of large files, and it tends to be unique to fiber.

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.

Rent a Gateway or bring your own networking equipment

Cox’s Panoramic Wi-Fi Gateway ($13/month to rent) is a modem and router in one, and you can purchase (but not rent) additional Wi-Fi pods ($129.99 each) that plug into a regular power outlet to reduce dead spots in your home. Because these pods can be used only with Cox, they're only an ideal solution if you plan to be with Cox for several years. The good news is Cox is also compatible with tons of other modems and routers, so you could save a few bucks while using your own gear.

With Cox, a self-installation kit is free. But if getting set up on your own makes you sweat, a Cox professional can install it for $100... but that installation cost goes up if your home isn’t already wired up and ready to go. They’ll ensure cabling makes it from the street into your home, but you might need to hire a contractor or handyman to run wires to a specific room.

No charges for equipment—seriously

Frontier redeems itself in a big way when it comes to equipment and installation. If you have Frontier's DSL internet, the equipment itself is fairly standard. It works, but it doesn't look great on a desk and the capabilities are limited. It's free, which is nice, but you might still want to use your own gear if you need more control over which devices on your network get bandwidth priority. DSL installation costs $85, and there's no self-install option.

If you have fiber internet from Frontier, you're in luck! You get free rental of an eero 6 on the Fiber 1 Gig plan or an eero6E mesh Wi-Fi system, on the Fiber 2 Gig plan. If you have the 5 Gig plan, you'll get the TP-Link AXE300 6E with an optional TP-Link RE815XE Wi-Fi extender for an extra $10 per month. You could still technically use your own gear, but it's hard to do any better than the latest and greatest from eero and TP-Link.

If you're eligible, you may be able to get a Frontier self-install kit—otherwise, a professional will come to your house to install the internet for you. If you need a pro to come out, you'll be charged $50 on your first bill. Cancelation is also free, but some customers are charged a $20 restocking fee for rented fiber gear and a $50 restocking fee on DSL gear.

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.

Decent customer service, and you can pay for extra tech help

Reviews for internet service providers are notoriously low in general, but Cox does pretty well according to our real customer reviews. The American Customer Satisfaction Index (ASCI) ranks Cox ninth in customer satisfaction among internet service providers—the same as Frontier. (2) That's lower than average, but not by much.

We think Cox’s 30-day, no hassle money-back guarantee is solid. And in our own experience with Cox, we've had solid customer service interactions. If you opt for self-installation, you can still get plenty of help online or by phone if needed. But if you use your own gear or technology isn’t your thing, $10/month will get you extra help, day or night, for things like malware removal, software installation and reconfiguration, and general troubleshooting.

Customer experience
2.5
Plenty of unsatisfied customers, and you can't order online

The Frontier customer experience is a mixed bag. The service itself is fairly reliable—especially the fiber. The DSL service is relatively stable, but more prone to slowdowns during heavy traffic times (like the evening). We’ve also seen some reports online of speeds that are inconsistent with what’s advertised, so keep that in mind.

Frontier has also received very low scores in customer satisfaction from organizations like the American Customer Satisfaction Index (ACSI). (3) The provider ranked second-worst in overall satisfaction in the most recent surveys, falling well below average. The complaints we’ve seen point generally to a broad pattern of poor customer service, so if that’s a key factor in your choice of provider, you might want to steer clear until Frontier can sort out its issues.

Unlike most internet service providers, the only way to order internet service is to call in. It works okay for most people, but some folks love the convenience of handling everything without having to deal with phone trees, wait on hold, or talk to a live human. At least the hold music is nice, though, and you can enter info via text message!
