AT&T vs. Mediacom 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.
Mediacom offers a decent overall experience, with fast speeds and modern Wi-Fi gear. However, big rate hikes, a hefty installation cost, and lots of small fees bring the rating down.
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.
Rating Mediacom’s value requires a long-term mindset. When you first sign up, the prices are extremely low—possibly the best on the market. Some come in at just 20% of the national benchmark, if you opt for paperless billing and autopay (1). However, each year, your cost gradually increases until it reaches a “standard value” (usually after three years). These prices are less exciting: you’ll end up paying roughly double what you initially signed up for. Depending on the length of your contract term, you may be able to jump ship before the price gets too high, but this might be too much effort for some.
Now, to be fair, many internet service providers (ISPs) do this (with a few notable exceptions, like CenturyLink). Mediacom is also pretty transparent about these price hikes and when you can expect them. However, the low starting prices here make the increases feel worse than they are, and that’s not great.
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.
We have no major complaints about Mediacom’s performance. There’s a range of plans available (up to 1 Gbps), so you can find something to suit whatever your needs are. We do have a couple of small gripes, though.
First, there are data caps on all internet plans, with no unlimited data option. The lowest-tier package has a cap of just 350 GB, which is pretty harsh, given the average person uses 536 GB per month (2). The middle-tier internet plans have 1.5 and 3 TB limits, and that's better—this should be plenty for most users and is in line with most other providers that have data caps.
The 1 Gbps plan bumps data caps up to 6 TB, which is effectively unlimited for most use cases, although a household streaming in 4K could theoretically max this one out, too. Going over the cap costs $10 per 50 GB, which, again, is in line with other providers charging overage fees.
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.
Mediacom offers a home networking combo called Xtream WiFi360pro. It uses a cable modem and eero Pro 6 mesh routers to ensure coverage over your whole house. The cost is $10 per month for a pair of routers, and you can add additional units for $6 each if needed.
Installation is less exciting. A professional installation and an activation fee will cost you around $120 total, and there’s no option to do it yourself. The fees can sometimes be waived with certain promotions—we recommend shopping around for one or asking a sales rep because these are steep.

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.
The Mediacom customer experience is decent overall. The provider scores a bit below average on customer satisfaction surveys like the American Customer Satisfaction Index (ACSI) (3), but overall, the service itself is fine. Speeds are solid and reliable, the Wi-Fi equipment is good, and the prices are competitive (at least initially).
Our biggest knock against Mediacom is the tremendous amount of small fees the company hits you with. In addition to the equipment and installation fees already mentioned, the company charges one-time fees for activation, early termination of your contract, and “Wi-Fi certification” (whatever that means). There’s a fee every time you have a technician come out for service. All these fees add up and can really sour the experience over time.
