Some of the best value for fiber internet

AT&T offers one of the best values in internet service—fast fiber internet speeds at reasonable prices, plus some of the best support in the business and rock-solid reliability. With no contracts, no data caps, and no monthly equipment fee, AT&T is one of the best home internet providers we tested.

What we like

  • Competitive fiber plans
  • Solid customer support
  • Excellent reliability
What we dislike

  • Expensive installation fees
  • Higher monthly prices than some competitors
  • Few TV bundling options
Savings tip: AT&T 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

Hyper-gig download speeds and improving customer service

Xfinity is a fantastic provider overall. It offers fast speeds, reliable service, and reasonable prices. Some plans still require contracts, and others still have data limits. Watch out for Xfinity’s hidden fees and spotty customer service record, but it may not be as bad as it once was.

What we like

  • Consistently fast speeds
  • Wide availability around the country
  • Competitive pricing, especially for budget plans
What we dislike

  • Data caps on slower plans (unless you pay more)
  • Inconsistent pricing and speed availability
  • Reputation for poor customer service

Fiber internet is a great deal

The AT&T fiber plans represent an excellent value proposition. The speeds are competitive, and the prices at any given tier are lower than nearly every other provider. One exception, Xfinity, offers slightly cheaper gig plans in some markets. Another, Google Fiber, offers $10 less on gigabit speeds. However, AT&T is more likely to be available in areas that have cable internet from Spectrum and Cox, and we think AT&T fiber is usually the better deal.

For the money with AT&T, you get outstanding download speeds and excellent upload speeds. And with unlimited data on fiber internet plans, you can actually use your gigabit connection without worry.

Some legacy customers may have DSL internet from AT&T. The most affordable AT&T plan is more than $50 per month, but this can either be basic DSL (speeds up to 75 Mbps) or the excellent, fiber-based Internet 300. If you can get only AT&T fixed wireless, you’ll pay higher prices, face data caps, and suffer through 1 Mbps upload speeds. Other providers just offer much better deals on plans in these tiers.

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.

Budget broadband internet plans are a great deal

Xfinity is generally a very good value, especially at the middle and lower tiers. In fact, it offers some of the best budget plans of any of the major internet service providers, with a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month in some areas. Those plans have a data cap of 1.2 terabytes per month, which is disappointing but common among cable internet service providers (ISPs). Removing it costs an extra $30.

The 400 Mbps plan, which is about right for an average family, is also a great price. It rings in at about 36% of the national benchmark in its range. (1) That means you're paying just $0.18 per megabit, with plenty of megabits to go around.

Faster plans are available, but they are pretty pricey compared to the best fiber internet competitors we reviewed. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. That is ludicrously fast, but it’s also really expensive. Most households don’t need those internet speeds unless they’re streaming a ton of 4K content at the same time or have 10 or more users, so we don’t recommend them for most households. They do come with unlimited data, though, so might still be worth it for some households.

Fast, reliable speeds any time of day

AT&T claims 99% reliability (1) for its fiber internet service, and that’s pretty accurate in our experience. In fact, over several years of constant daily use in a packed house (two people working from home, two kids doing schoolwork, lots of streaming video and calls), we haven’t had a single major disruption. This is a marked contrast to our previous provider.

Additionally, speeds are consistent, with little variation based on the time of day, activity, or even the particular speed test used. Its median download speeds are slightly slower than its cable and fiber internet competitors, but only by a matter of milliseconds (2). This all adds up to a great experience where the service “just works,” and nobody ever really needs to wonder if they’ll be able to do what they need to do.

It's also worth mentioning that because AT&T fiber internet uses fiber-optic cables, upload speeds are equal to download speeds. That means you can upload huge files in seconds, video chat, live stream game play, and more without a hiccup.

Available speeds vary by location. Call 1-833-804-1770 to speak with a AT&T 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.

Some of the best internet reliability we found

Xfinity internet performance is excellent. Its speeds are fast and reliable. In fact, in many markets, it has one of the fastest internet speeds around. The service is reliable and consistent. If outages occur, Xfinity is responsive and generally restores service within hours. Xfinity internet is also highly rated for speed (2), and research from the US Federal Communication Commission (FCC) scored it among the top for reliability (3).

Equipment and installation
4.0
Free equipment and free self-installs for fiber internet

AT&T fiber internet installation is about as simple as it gets. You have two options: a $99 professional installation by an AT&T technician or a DIY self-install kit.

If you can get only DSL with AT&T, the equipment is still free but you'll be charged a $49 activation fee. If you don't want to self-install, you can have a pro come out for an additional $99.

The self-install is very easy and comes with clear instructions, so we’d recommend that for pretty much everyone. Activation and configuration of your Wi-Fi network are handled through the simple AT&T Smart Home Manager app, so you don’t even need to log into the router settings page like with some other providers.

It is worth noting that both of these charges are a bit higher than what the competition charges. CenturyLink doesn’t charge for self-installation, for example, while Xfinity charges only $89.99 for a professional install.

That said, if you do need a professional to come out, you can count on fast and friendly service. We’ve personally had techs out on a couple of occasions and were happy with the experience.

Learn more about whether you need a professional installation.

Finally, the AT&T wireless gateway is surprisingly nice. Called AT&T Smart Wi-Fi, it’s super simple to set up, provides solid range, and looks decent on a desk. Compared to the routers and gateways provided by some other providers, this one’s a breath of fresh air.

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.

Typical installation fees and Wi-Fi equipment

Xfinity internet offers the usual choice of professional and self-installation. The professional option is often more affordable than competitors, at $100. It's required if you haven't had Xfinity service at the address for more than 12 months. The self-install kit is free, though you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help but may face long hold times.

As for equipment, the Xfinity xFi gateway is fairly typical (and costs a fairly typical $14 per month). You can also add a Wi-Fi extender (and unlimited data) if you bump up to xFi Complete for about $15 per month for the first two years (and $25 per month starting in year 3). This is a bit steep for just the extender—you can grab an excellent Wi-Fi extender for right around $50. However, using Xfinity's equipment gives you unlimited data, and you qualify for a free upgrade after three years.

If you use your own equipment, unlimited data costs an extra $30 per month for lower tier plans, but is included for plans of at least 1 Gbps.

Better customer service, with more options

Internet providers have traditionally had a terrible reputation for customer service, but AT&T scores above average with national rating organizations like the American Customer Satisfaction Index (ACSI). These ratings have improved over the last few years, which is encouraging.

AT&T offers several options for getting help:

The support site also has lots of information available. It’s easy to use, and if you do need more help, the options involving service reps usually get a quick, friendly response. While it’s not perfect 100% of the time, AT&T customer support tends to be better than average.

AT&T makes it easy to stay connected away from home, too. Subscribers get access to a nationwide network of free Wi-Fi hotspots. Since AT&T offers mobile phone service in addition to internet, you'll be able to log on in from almost anywhere.

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.

Rapidly improving customer service scores

The Xfinity internet customer experience is kind of a mixed bag. On the one hand, you have reliable service, with the option for unlimited data if you want it. This makes for a great day-to-day experience.

On the other hand, Xfinity internet has a spotty customer service track record. Technically, it ranks above average on customer surveys (4). That said, we all remember the memes from a few years ago. While customer service seems to be improving (based on survey scores, at least), not everyone has a great experience, and we still see a lot of complaints about billing issues and miscommunication between the company and the techs it hires.

If you need to connect with the company, we recommend using its customer service portal and downloading the Xfinity app first before trying to reach reps by phone.
