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
  • Steep data overages
  • So-so availability

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

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.

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.

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 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.

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.

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.

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.

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.

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

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
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.
