AT&T vs. Cox Communications Internet plan comparison





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

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.
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.
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.
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.
