When the competition is AT&T Fiber vs. Xfinity Internet, we say AT&T is better than Xfinity. While our recent customer satisfaction survey put AT&T Fiber and Xfinity Internet on equal footing for reliability, we think you’ll get a lot more bang for your buck if you go with AT&T Fiber.

However, AT&T’s legacy network is a DSL and fiber internet hybrid, which isn’t as fast as its fiber-to-home tech. If you’ve got both AT&T and Xfinity in your area, make sure it’s AT&T Fiber internet before you try to sign up.

On most fronts, Xfinity internet and AT&T internet aren’t drastically different. Xfinity’s slower internet speeds are cheaper than AT&T’s slow DSL and fiber plans. But AT&T’s high-speed fiber plans are cheaper than Xfinity’s, so you’ll get a lot of bang for your buck with AT&T.

And while both providers have a reasonably sized data cap on some plans, most of AT&T’s plans come with unlimited data. In comparison, Xfinity’s only plan with unlimited data is the superfast, uber-expensive Gigabit Pro.

So if you have a lot of folks using your internet, or you download large files regularly, AT&T is the better choice to avoid overage fees.

When renting internet equipment, Xfinity’s Wi-Fi gateway will cost you $4 more per month than AT&T’s. However, Xfinity lets you bring your own compatible modem and router instead, while that’s not an option with AT&T.

If you’re looking for a way to cut down on monthly costs, skipping Xfinity’s provided Wi-Fi gateway is an excellent way to go.

Packages and pricing

If you’re the only person using your internet, check out the cheap plans in the lower range of Xfinity’s speeds. But if you’ve got a lot of folks at home, you can keep them all connected at an affordable price with AT&T’s plans.

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 Plus (50 Mbps) to the impressive-for-cable Gigabit (1,200 Mbps).

We like middle plans Performance Select (100 Mbps) and Performance Pro Plus (200 Mbps) for the average user, both of which offer plenty of speed at a manageable price. AT&T’s fiber internet will give you a better bang for your buck, but these Xfinity plans are a great alternative to AT&T’s DSL/fiber hybrid internet.

Editor’s note

“I personally have the Xfinity Performance Plus plan. I chose it based on the price-to-download-speed ratio. It’s only $29.99 per month in my area and generally performs well. But I do get some buffering when I’m streaming Netflix and Hulu in the evening, which is probably because I share bandwidth with the other Xfinity customers in my building.

Other than that, the price makes it worth it, especially since I haven’t had any customer service problems like other online reviewers have experienced.”

Mike Strayer, Managing Editor

If you’re running a home business where speed counts, Blast! Pro (400 Mbps) or Gigabit might be a wiser option. Remember that cable (and DSL) internet download speeds don’t mean equal upload speeds: for example, 100 Mbps download will get you only about 5 Mbps upload.

AT&T’s fiber plans are a much better deal than Xfinity’s high-speed plans, though, so if you have the option, we’d say save yourself a buck and go with AT&T.

Based on where you live, your AT&T’s DSL and fiber hybrid internet plan could be anywhere from less than 1 Mbps to as high as 100 Mbps. Unfortunately, no matter what speed you get, you’ll still have to pay $45 a month.

The best AT&T hybrid plan is AT&T Internet 100. You’ll get unlimited data, just like you would with AT&T Fiber plans. But this plan is still more expensive than AT&T Fiber Internet 300, which has three times faster internet speeds. AT&T’s hybrid internet just can’t keep up with its fiber internet counterpart.

Xfinity’s starting plans are much more affordable, so we say stick with Xfinity for plans up to 100—unless you need the unlimited data that comes with AT&T Internet 100.

Fiber offers a more consistent internet experience than cable and DSL, in more ways than one. 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.

Plus, AT&T Fiber comes with no data caps, so you don’t have to worry about going over your monthly data allowance and being slapped with a fine like you would with an Xfinity plan.

Compared to what you get with Xfinity, any of AT&T’s fiber plans offer an excellent deal price-to-speed-wise. If fiber is available in your neighborhood, we say jump on it.

Xfinity vs. AT&T fees and extra charges

With any internet service, you’ll probably end up paying more than the advertised price. Here are some hidden fees from Xfinity and AT&T to keep an eye out for.

Xfinity fees and extra charges

Professional installation
Modem/router rental
Data overage fee
Reactivation fee
Late payment fee
Taxes and surcharges
$10.00 per 50 GB over 1.2 TB

Some of Xfinity’s one-time fees are unavoidable—but you can purchase your own modem/router to use with Xfinity internet, which eventually saves you money compared to renting month to month. Just be prepared to do most of your own troubleshooting.

If you somehow surpass Xfinity’s monthly internet data cap (1.2 TB), you’ll be charged $10 for every 50 GB you go over. How much is a TB (terabyte) of data? To give you an idea, you’d have to stream over 11 hours of Hulu shows every day for a month to hit it.

Unlike Xfinity, AT&T doesn’t have a bring-your-own-modem option: you’ve got to take the company equipment for $10 a month. It’s unlikely you’ll find another modem that would work with AT&T’s network anyway.

Except for the $35 reactivation fee (ouch), AT&T’s extra costs are fairly similar to Xfinity’s. Check the table above for all the details.

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 internet line since most of what you’ll need is already in place.

Need help installing your Xfinity home internet? We’ve got a complete walkthrough for you.

If you have no existing internet hookups, on the other hand, you’ll want a professional for that from-scratch installation. The same goes for a new fiber installation, which many homes aren’t equipped for yet. If you don’t know whether your home is set up for fiber, check with your internet service provider.

Important note: Xfinity offers a 30-day money-back guarantee on internet service 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, go for Xfinity. There are many Xfinity-compatible modems on the market. Unfortunately, AT&T doesn’t let you bring a third-party modem to your service.

Xfinity vs. AT&T bundling with TV

Want to save some cash on TV and internet? Bundling your Xfinity services is the way to go—you’ll save $20 per month, based on what the services would cost alone.

But while you can bundle your AT&T internet with DIRECTV, AT&T doesn’t offer any bundling savings.

Final take: Is Xfinity or AT&T better?

Xfinity cable internet offers more speed in more places than either AT&T DSL internet or AT&T Fiber internet, 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 while its starting plans are affordable, its high-speed plans cost more than AT&T’s.

AT&T’s DSL internet isn’t as fast as Xfinity’s, and it can be a bit pricey. But AT&T Fiber is an especially great deal—if you can get it.
