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
Savings tip: Cox often has sign-up promotions for first-time customers. Call to ask a rep about current deals and discounts.

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

Inexpensive high-speed internet with no contracts

T-Mobile provides an inexpensive 5G internet plan with no contract and decent speed, but not a lot of choices or professional installation.

What we like

  • One low price
  • No commitment
  • Relatively fast
What we dislike

  • Not widely available
  • No professional installation available
  • Inconsistent speeds

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.

One plan, one very low price

T-Mobile 5G Home Internet comes in one download speed (182 Mbps), which is fast enough for a lot of people but slower than most cable plans (up to 1 Gbps) and fiber plans (up to 5 Gbps). The good news? T-Mobile’s plan includes unlimited data, but there may be slowdowns when the network is congested. It’ll cost you $50, which is $0.50 per Mbps, and about right for 5G plans. However, overall, 5G internet is super cheap compared to other kinds of broadband internet. The Federal Communications Commission (FCC) benchmarks similar broadband plans at $105.67/month, (1) which comes out to more than a dollar per Mbps!

Even better, if you’re already a T-Mobile customer with a qualifying Magenta plan, your rate is $25/month. If max download speeds of 100 Mbps works for you, T-Mobile 5G Home Internet is a pretty sweet deal, especially if you’re already a customer. But if you’re looking for more plan options, you won’t find them here.

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.

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.

Available speeds vary by location. Call 1-833-804-4930 to speak with a EarthLink rep or

3.0
Faster than advertised, but awkwardly unpredictable

As with any fixed wireless internet provider, speeds fluctuate widely and can be affected by weather, terrain, peak hours, and more. That means you’ll rarely get a steady 100 Mbps. T-Mobile says you’ll likely see anywhere from 33 to 182 Mbps for download and 8 to 25 Mbps for upload. (2) But we think T-Mobile should toot its horn a little louder. Independent research shows speeds average out to around 119 Mbps for download and 16 Mbps for upload—both of which leave other wireless ISPs in the dust. (3)

Generally, 5G internet isn’t as fast as cable internet (up to 1,000 Mbps, or 1 Gbps) or fiber (up to 5 Gbps). But for most people, it’ll feel pretty zippy. Unfortunately, if you’re using your connection for gaming, the inconsistency could cause unpredictable, frustrating lags.

Equipment and installation
3.5
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.

You’ll need an app for that

T-Mobile uses a 5G gateway (included at no additional cost) to turn cell signal into Wi-Fi for your home. It’s strong enough to send signal about 30 feet away, depending on how many walls are in the way. It’s compatible with most mesh network extenders. Plus, you can create up to four separate networks, so you can create one for Airbnb guests or your least favorite roommate.

According to T-Mobile, installation should take around 15 minutes—if you have an Android or iOS phone and can download the T-Mobile internet app. If that doesn’t work out, you can call T-Mobile customer service and someone will help you get set up. If you don’t get cell signal or a landline at home, though, you’re going to have a rough day.

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.

Award-winning customer service, but a lackluster guarantee

T-Mobile is fairly new to providing home internet, but it has a solid track record of providing great service to its mobile customers. Both contract and non-contract customers see the best service in the industry, according to J.D. Power. (4)

We don’t like T-Mobile’s short 15-day money-back guarantee, which doesn’t give you much time for a test drive. (We much prefer Starry’s 30-day guarantee.) Even worse, your countdown starts when T-Mobile ships your 5G Gateway, not when it arrives. If there are any shipping delays or it takes you a day or two to get set up, you’ll run out of testing time fast.
