The bottom line
Xfinity cable internet is not only available nearly everywhere, but also fast anywhere you get it. Cable is already the second-best connection out there, and Xfinity is building infrastructure toward the first-best connection: fiber. Unfortunately, the company’s fiber coverage is still limited, and its overall customer service reputation is the stuff of internet legend (read: full-scale contempt).
According to the numbers, AT&T does better by its customers, and its internet coverage is close to that of Xfinity’s. But right now, that coverage is mostly telephone-line DSL, the slowest connection available above old-school dial-up (yes, that’s still a thing) and satellite internet (which isn’t as fast as you’d assume). Like with Xfinity, AT&T’s fiber footprint is still toddler-sized.

On most fronts, Xfinity internet and AT&T internet aren’t drastically different. Xfinity’s speed range is higher thanks to its legacy coaxial cable lines, but its promise of 2,000 Mbps fiber comes with several caveats regarding availability and required equipment.
AT&T’s 1,000 Mbps connection—known as AT&T Fiber—is closer to the fiber norm, which would put both providers on equal footing once complete US fiber coverage happens. That’s still years away, though—by then, we could have bioengineered telepathic internet. Those could be some wild service reviews: stay tuned.
Xfinity vs. AT&T prices and plans
Xfinity pricing and plans
Plan | Price‡ | Max download speed | Connection type |
---|---|---|---|
Performance Starter | $29.99/mo. | 15 Mbps | Cable |
Performance Plus | $39.99/mo. | 60 Mbps | Cable |
Performance Pro | $54.99/mo. | 150 Mbps | Cable |
Blast! Pro | $69.99/mo. | 250 Mbps | Cable |
Gigabit | $109.99/mo. | 1,000 Mbps (1 Gbps) | Cable |
X1 Gigabit Pro | $299.99/mo. | 2,000 Mbps (2 Gbps) | Cable |
Not all of Xfinity’s plans are available in all service areas. Being fiber-based, the insanely fast (and expensive) X1 Gigabit Pro will be the most difficult to get. You’d also need the gear to keep up with it—your five-year-old laptop probably won’t be able to achieve 2,000 Mbps, as Xfinity lays out.
The rest of the plans are cable internet, ranging from the aptly named Performance Starter (15 Mbps) to the impressive-for-cable Gigabit (1,000 Mbps). For the average user, we like middle plans Performance Plus (60 Mbps) and Performance Pro (150 Mbps), both of which offer plenty of speed at a manageable price.
If you’re running a home business where speed really counts, Blast! Pro (250 Mbps) or Gigabit might be a smarter option. Keep in mind that cable (and DSL) internet download speeds don’t mean equal upload speeds: for example, 150 Mbps download will get you only about 10 Mbps upload.
AT&T pricing and plans
Plan |
Internet 100 |
Internet 1000 |
Price | Max download speed | Type |
$35.00-$45.00* | 5 Mbps–100 Mbps | DSL |
$60.00/mo.† | 940 Mbps | Fiber |
Let’s just ignore AT&T’s Internet Basic plan—5 Mbps is barely adequate to send an email that simply says, “Couldn’t upload the attachment; will drop off a floppy disk.” So 1999.
The speed range of the Internet 100 package only looks confusing because it is; it’s dependent on the infrastructure of your area. Some locales have the line capacity to deliver only 10 Mbps, others can do 100 Mbps. DSL is uneven like that.
Fiber is a more uniform internet experience, in more ways than one. Unlike cable and DSL, fiber internet’s upload speeds mirror its download speeds—which means no more waiting for an hour for the latest episode of your Typography Talk podcast to upload.
Obviously, in the DSL tier, we’d recommend the fastest plan available. Also, any of AT&T’s fiber plans, compared to what you get with Xfinity, are a great deal price-to-speed-wise. If fiber is available in your neighborhood, we say jump on it.

As with any provider, most one-time fees are unavoidable—but you can purchase your own modem/router to use with Xfinity internet, which eventually saves you money over renting month to month. Just be prepared to do most of your own troubleshooting.
If you somehow surpass Xfinity’s monthly internet data cap (1 TB), you’ll be charged $10 for every 50 GB you go over. How much is a TB (terabyte) of data? You’d have to stream over 11 hours of Hulu shows every day for a month to hit it. (We’d be willing to put Letterkenny on a perpetual loop to test this, btw.)

Unlike Xfinity, AT&T doesn’t have a rental option for its modems/routers: you either take the company equipment (included with install price) or shop for your own. Either way, you own it.
With the exception of the $35 reactivation fee (ouch), AT&T’s extra fees aren’t much different than Xfinity’s—including the 1 TB data cap. Our Letterkenny challenge still stands.

Both Xfinity and AT&T can mail kits to your home for self-installation, which is a cheaper route if you’re looking at a simple setup. You shouldn’t need a technician to connect to a previously-installed cable or DSL line, since most what you’ll need is already in place.
From-scratch installation in a home or office with no existing internet hookup, on the other hand, will likely need a professional’s touch. The same goes for a new fiber installation, which uses different lines and equipment than cable or DSL. If you don’t know, call a pro.
Important note: Xfinity offers a 30-day money-back guarantee on its service, whereas AT&T allows only a 14-day trial period.

Xfinity and AT&T make their own modem/routers available for new customers, which can be helpful. Both providers offer 24/7 support and regular software updates.
If you don’t want to use the company gear and would rather buy your own third-party modem/router, there are several alternatives available for Xfinity and AT&T service.

Bundling with TV
Need TV service to go with your internet? Not a problem: Xfinity was a cable TV company long before it was an internet provider, and AT&T owns DIRECTV. We’ve reviewed them head-to-head, and we like both TV services for different reasons—either could complete a cool bundle.
Our final take
Xfinity offers more speed in more places, plain and simple. Its cables cover a good chunk of the US, and cable internet has upped its tech considerably in recent years to keep up with fiber. But more speed and more availability costs more money.
AT&T’s DSL internet, while not as fast as Xfinity’s, still hits decent speeds that an average household could make use of and more easily afford. AT&T Fiber is an especially great deal, if you can get it—since it’s rolling out aggressively, it could be available near you sooner than Xfinity’s fiber alternative. AT&T customers also seem to be happier—and you can’t put a price on that.
Xfinity vs. AT&T FAQ
Which has faster internet, Xfinity or AT&T?
Comparing base delivery systems, Xfinity’s cable internet has faster speeds than AT&T’s phone-line DSL—more than double, in some cases. Most internet surfers probably wouldn’t see much difference between 100 Mbps (AT&T’s top DSL speed) and 250 Mbps (Xfinity’s second-best cable speed), but connection speed becomes more dramatically noticeable in the 1,000 Mbps (1 Gbps) range.
What’s the difference between DSL, cable, and fiber internet?
DSL (digital subscriber line) uses telephone wires, while cable internet is delivered through cable TV lines. Fiber, the newest (and least available) internet upgrade, uses fiber-optic glass strands to transfer data as bursts of light. It’s the fastest and most efficient internet connection there is in 2019, but the infrastructure hasn’t yet caught up to the demand.
