Comcast Xfinity Internet Review

Comcast Xfinity offers a lot of variety when it comes to plans-- and speeds are fast and reliable. We do wish their customer service was a bit better, though.

Comcast Xfinity is one of the largest and most widespread cable internet service providers (ISPs) in the U.S., with service available in 41 states. It’s one of the fastest and most reliable ISPs around, with naming them #1 for both top speeds and consistency, contributing to why we named them our #1 overall choice for best internet provider. But Xfinity’s plans vary, plus their prices can be higher than competitors offering similar speeds — so are they really that good? And more importantly, are they the best choice for you? Let’s find out.

**Actual speeds vary with location.

While there are a lot of Comcast Xfinity internet options, which is great, there’s a pretty big kicker: while varying availability for faster speed plans is a general rule with ISPs, changing prices should not be.

If you’ve been wondering, “How much is Comcast internet going to set me back?” Well, that’s exactly the problem we were just alluding to. While you may pay $29.99 a month for 15 or 25Mbps, I might pay just $19.99 a month. Inversely, of course, you might pay just $19.99 a month while I would pay $29.99 a month, instead — so it can work both ways.

That said, you can get some consistent, fast speeds for “okay” prices in most cases. But not always — the Xfinity Blast! Pro internet package nets you a top-end speed of 250Mbps for $59.99 a month, while Charter Spectrum offers up to 200Mbps for the $44.99.

Yet it’s worth remembering that you’re more likely to actually reach faster speeds with Xfinity than with Spectrum, which we’ll discuss a little later.

Bundling options

Plan Speeds Price View Plan
X1 Saver Pro Double Play 100Mbps $79.99/mo. View plans
X1 Starter Pro Triple Play 250Mbps $109.99/mo View plans
X1 Premier Pro Triple Play 1000Mbps $159.99/mo. View plans

Xfinity also offers a variety of cable and internet bundles that give you decent combos of internet speed and cable channels — my options were anywhere from 140 digital channels to almost 300, including popular ones like ESPN, HGTV, and TBS. The third option even gave me HBO, CINEMAX, and SHOWTIME.

Flexible data plan

A cool thing that Xfinity offers is the “Flexible Data Option.” It’s a cool internet deal designed for super light data users and is available for Performance Starter customers. Basically, you get back $5 if you use 5GB or less of data each month.

But on the flip side, if you have the FDO activated and go over 5GB? You won’t get your $5 credit and you’ll get charged $1 per GB over– up to $200.

So, Xfinity recommends you track your data usage on the normal plan first to see if it’ll be a good fit for you. It’s also important that you’re aware of how visitors might be using your internet; for instance, don’t let someone download a huge 50+ GB game.

Contracts + fees

Another great thing about Xfinity: if you are looking for into getting Xfinity internet only, they offer both no-contract and 12-month contract options. Go with the contract, and you’ll save about $10 bucks a month– which could net you a total of $120 in savings for the year. Not bad.

Still, if you prefer no-contract, you can do that and cancel any time, no fees.

And a side note: once your comcast internet deal as a new customer (if no contract) or your contract is over (with the 12-month), expect prices to go up by $15-$20 a month.

Editor’s Note: the basic plan for me is $20 a month for the first year thanks to a $20 discount for the first year and a $10 discount for doing a contract. Without either of those, I’d be paying $50 a month.

That said, Xfinity takes back some of the power it exchanges in giving no-contract options by tacking on fees. The “good” news is these are fees that are standard for most ISPs, so nothing new here when compared to competitors:

  • Installation: Depending on the plan you choose and where you live, this Xfinity’s installation fee can vary quite a bit. But rest assured (or uneasy) knowing it can cost you between $60 and $500. On some plans, though, you can do a self-installation option, which will only cost $29.95.
  • Equipment rental: The modem and router will cost you $11 a month, but you can also bring your own instead — just check here to see if it’ll be approved.
  • Late fee: $10 for a late payment
  • Data overage: It’ll cost you $10 per 50GB over; however, with a 1TB data cap, you probably won’t have an issue here.
  • Early Termination Fee: If you go with a contract, then decide to cancel part way through, you may face early termination fees based on the remainder of your contract length.
  • Reactivation: If you cancel your service, then would like to have it reactivated, you’ll pay $6. 

One thing Xfinity definitely has going for it is fast, reliable upload speeds, including the highest top speed: 2,000Mbps, or 2Gbps — more than double their competitors AT&T internet or Spectrum.

According to the FCC, you’ll actually get the speeds you pay for when you subscribe to Xfinity. While previous reports indicated that 80% of users were getting at least 99% of advertised speeds (not bad at all), the latest report actually shows a higher percentage of users getting greater than 100% of advertised speeds.

Essentially, the first report showed that if there were 100 people that had purchased 100Mbps internet, at least 80 of them were getting 99Mbps speeds; the latest report, from 2018, showed users getting greater than 100Mbps speeds for the same.

Other speed tests have shown Xfinity to have not only fast speeds but also the most reliable ones, too. Ookla’s was one such test, with 84.5% of speed samples taken from a variety of different regions met or exceeded a minimum threshold of 25Mbps. Spectrum was the next-closest for reliability, with 83.5% of samples achieving the same result.

All in all, Xfinity’s internet performance is one of the best in the industry.

Comcast Xfinity does apply a data cap to your internet. However, it’s a 1TB cap — you’d have to play video games 48 out of 24 hours a day for 30 days without stop, plus binge 629 episodes of the Simpsons in HD to use it all up.

If you do exceed that limit, you won’t find your speeds slowed down; no, you’ll be automatically given a “block” of 50GB of extra data and charged $10 per block, up to $200 a month.

But, if you’re one of these super-users, Comcast offers an Unlimited Data Option. It costs $50 extra per month, but you won’t face any overage charges.

You’d have to use 5 whole extra 50GB blocks, or 1250GB total, to actually make it worth paying that extra $50, though. Because of this and the generous data allowance, Xfinity strongly recommends you track your data usage from your account before upgrading.

J.D. Power ranked Comcast Xfinity with just 2 power circles in 2018, labeling them “The Rest” (i.e. average or below). The American Customer Satisfaction Index (ACSI) scored them 60/100, putting them in the middle of the pack. Given the internet service industry’s poor record for customer service, that’s about what can be expected.

Online reviews are none too kindly to the cable giant, either, complaining most about service outages, expensive prices, and a lack of personal attention. As always, it’s important to remember that forums and reviews reflect a minuscule portion of subscribers, and typically the ones with the worst things to say.

In any case, Xfinity’s support center is fairly easy to navigate. They offer a wide range of ways to contact them, as well as community forums: Phone: 1-800-934-6489 Twitter: @Xfinity Messenger Xfinity Support Forums Reddit

Our reviews Review Review Review Review

Comcast’s prices start at just $29.99 a month (in some areas, $19.99), making them at first glance the cheapest of the ISPs we compare here. But, that’s also for the lowest data speeds (15Mbps), too. Comparable starting speeds (100Mbps for competitors, 150Mbps for Xfinity) favor Xfinity slightly more, and then at the top of competitors’ speed (940-1000Mbps) Xfinity balances out about right.

But, as prices are pretty similar across the board, there are other reasons to consider different providers.

AT&T Internet

AT&T Internet ranked well in customer satisfaction by the ACSI, just 1 point behind Verizon Fios. They actually earned the #1 spot by J.D. Power in 2018, too. And when it comes to price-for-data, you might get a little more out of AT&T.

For example, AT&T internet starts at 100Mbps for just $40 a month. Comcast’s closest plan to that gives you just 60Mbps for $34.99. A small difference, certainly, but it’s an extra 40Mbps of speed for just a few bucks.


Charter Spectrum’s plans start at 100Mbps -- more than 5 times higher than Xfinity’s starter pack. It is true, however, that you can get 50Mbps more from Xfinity’s Performance Pro plan for the same price -- assuming those speeds are available in your area.

That plan aside, Spectrum typically comes in about the same or a little cheaper. In some cases, it can be more expensive, depending on what speeds you’re able to get.

For example, Spectrum’s 30Mpbs plan all the way up to its 400Mbps plan cost just $44.99 a month. If you’re able to get the 200 or 400 Mbps speeds, then you’ll pay less-per-Mbps with Spectrum; if only the 30, 60, or 100Mbps speeds are available, then you’ll pay the same or more than for Xfinity.

Prices are similar, but Verizon Fios is only available in about 9 states currently, all on the eastern seaboard.


Xfinity is reliably fast and available across the country. Pretty much no matter where you are in their coverage area, you’ll be able to get at least 25Mbps speeds for your home internet. Whether that is at an affordable rate will depend on the plans available in your region — other ISPs may provide better.

We’d like to see Comcast improve their customer service and be a little more transparent about plans and pricing. But, as available speeds vary across the country, we can certainly understand it to some degree.

Overall, we still think they top much of the competition nationwide as the best overall internet service provider for most people.


What’s the difference between ‘Comcast’ and ‘Xfinity’?

Comcast is the overarching company; Xfinity is specific to Comcast’s TV, internet, and voice services. They’re often used interchangeably (as you’ve seen).

Is Comcast Xfinity available where I am?

Xfinity is available in 41 states, so it’s quite possible that they are. However, as they are a cable provider, they’re more limited to cities and surrounding regions. For example, take a look at this coverage map:

In less populous areas, like the American West and southwest, Xfinity is not available. You can use this link to input your zip code and see if they’re available where you live.

What speeds do I need for my household?

That depends on what you use your internet for, and how many users are typically on it at a time. For example:

Data speeds 15-60Mbps Up to 150Mbps Up to 250Mbps Up to 400Mbps Up to 1000Mbps
Number of devices connected at once Up to 5 Up to 8 Up to 11 12+ Unlimited
Best Uses Light streaming Stream + Download shows Download music + photos Multi-device streaming + Download shows faster + Download large files Download show within seconds + Multi-device HD streaming + Multiplayer gaming Heavy usage + Super speeds + Multiplayer gaming Ultra-heavy usage + Very large households

Other things aside from number of devices and usage can affect your speeds, too, though.

  • Outdated equipment – That includes your modem and router, as well as keeping your connected devices updated.
  • Modem/router placement – The best place to put your router is in the center of your home and away from any walls or other obstructions.

Does Xfinity offer fiber-optic internet?

Comcast uses primarily old-style copper coaxial cable to provide service. However, they’re beginning to offer some fiber-optic or partial-fiber-optic service in some areas, but this is a work in progress at the time of writing.

Traditional cable is still Xfinity’s primary means of providing service.
