Xfinity Review

If Comcast Xfinity is the main — or only — cable internet option where you live, then we have good news for you: Xfinity is one of the best internet service providers (ISPs) in the US. It offers a wide variety of plans, with download speeds ranging from 25 to 2,000 megabytes per second (Mbps). To top it off, Xfinity is ranked among the most reliable ISPs. This means that you’re a lot more likely to actually receive the internet speeds you pay for.

Xfinity's Claim

Xfinity claims that its internet delivers the most reliable high-speed internet and Wi-Fi for all devices, all the time.

Is it true?

Yes. Technically, we can’t call Xfinity the most reliable provider, as Optimum eked past it in the Federal Communication Commission’s (FCC’s) latest report. But Xfinity passes the 80/90 benchmark, meaning that at least 80% of customers receive advertised speeds 90% of the time. In terms of reliability, Xfinity beats most cable internet providers — and it far surpasses DSL and satellite options.

It’s also worth mentioning that, while Optimum took home the gold for reliability, it only serves four states. Xfinity Internet is available in 39. This means that in every state Xfinity serves — besides Connecticut, New Jersey, New York, and Pennsylvania — it really is the most reliable option. It’s also likely to be one of the fastest. In 2018, the internet performance ratings site ranked Xfinity as the fastest internet provider nationwide. Available speeds vary by location, so be sure to use our ZIP code tool to check plans in your area.

Standout Xfinity Features

Reliably fast internet

Xfinity Internet not only promises some of the fastest speeds available — from 15 Mbps up to 2,000 Mbps — but it also does a great job keeping that promise. Xfinity customers are more likely to actually experience the download speeds they pay for than those with other internet service providers. Proven reliability is the reason Xfinity was rated Fastest Internet Service Provider by SpeedTest in 2018.

Wide range of equipment features

Not many providers can match the variety of equipment that Xfinity offers. The xFi Gateway is one of the most intelligent and secure gateways in the industry, combining the traditional modem and router, while also boasts major security features. For an additional $5.99 per month, you’ll have access to Xfinity’s Advanced Security. With this add on, you can protect all your smart home devices from malware, phishing threats, and hackers. All you have to do is download the xFi app and you’ll receive real-time notifications giving you the ability to report and block any suspicious activity.

Those who opt to rent the xFi Gateway will also have access to XFi Pods. These little devices work to enhance WiFi coverage by eliminating dead spots and increasing connectivity range. These are ideal for anyone with a larger home that has battled with connectivity lapses in the past. We recommend talking to an Xfinity specialist to see if your home would actually benefit from an enhancement in coverage.

Generous data allowance

Even though Xfinity technically has a data cap, most customers will never have to worry about maxing out their internet usage. Xfinity sets its limit at 1 TB per month in most states; for context, two people can play online games 24 hours per day for 30 days straight and still have enough data left over to watch all 629 episodes of "The Simpsons" in high-def. In other words, Xfinity will feel unlimited to most people.

If your household does use more than 1 TB of data per month — think multiple people streaming on multiple devices every day — Xfinity has a solution. The service offers an Unlimited Data Option for an extra $50 per month. However, Xfinity recommends signing into your account to monitor your personal data usage before making the upgrade. You may find that 1 TB of data stretches further than you think.

Flexible contract options

Xfinity shines when it comes to contract flexibility, though the amount of available packages can be a bit overwhelming. With nine packages to pick from, it’s easy to get lost in all the deals and bundling options. We recommend looking at the higher speed packages first, as they provide the most value. For those looking to stay put for a few years, packages with 24 month locked-in prices can save you hundreds of dollars compared to month-to-month or 12 month options. When it comes to installing the equipment, Xfinity offers both professional installation as well as self installation for those looking to save a little extra money. For users who aren’t as tech-savvy and would rather have a professional come out, spend some time looking through all the deals as Xfinity often offers free professional installation (normally $60) for higher speed packages.

Xfinity also offers money-saving data plans for light internet users. If you only use Wi-Fi to check email and surf the web (rather than to stream video or online game), then you may be eligible to enroll in Xfinity’s Flexible Data Option. This plan credits $5 back each month to customers who use less than 5 GB of data. Before enrolling, though, be sure to verify that your data usage truly falls below that 5 GB mark — if not, you’ll be charged $1 for each extra gigabyte, up to $200 per month.

Ultra high-speed network options

Xfinity is currently rolling out Gig-speed internet — an ultra-fast fiber internet option that can reach download speeds of up to 2,000 Mbps (2 Gbps). The catch? Its Gig-speed connection is still in its early stages, and it's only available in a handful of cities. It’s also costly: Xfinity’s fastest fiber option rings in at a stunning $300 per month, with $500 installation and $500 activation fees. The lower-tier, 1 Gbps plan costs $110 per month (with a two-year agreement) — which is more reasonable, but still pricier than most cable internet plans.

Possible drawbacks

Customer service

ISPs don't rate highly for customer service, and Xfinity is no exception. It has a reputation for long wait times to reach a representative and difficulty disconnecting services. The American Customer Satisfaction Index, which conducts thousands of customer surveys annually, ranks Xfinity as fifth best out of 12 providers, but with a score that's below the national average. It’s not all bad news though. For the first time in many years, Xfinity saw a huge boost in rankings from J.D. Power, another independent third party. Xfinity received an average rating of 4/5 in customer satisfaction across the four major market segments: North Central, South, East, and West. That said, Xfinity is striving to make improvements by hiring more representatives and creating appointment slots to reduce hold times, so customers should see improvements in the future.


Xfinity isn’t always the best value when compared to the competition. For instance, $45 per month gets you up to 150 Mbps with Xfinity but up to 200 Mbps with Charter Spectrum. Of course, it’s worth remembering that Xfinity is more likely to meet its promised speeds than many other providers — so paying less with another ISP may still mean slower internet. As you would with any other provider, make sure you keep an eye on your bill for miscellaneous charges. Cable companies are notorious for adding additional taxes and fees.

Coverage varies by ZIP code. Check your address and see which Xfinity plans are available where you live.

What is the fastest Xfinity internet speed?

In most areas, Xfinity offers internet speeds between 15 and 250 Mbps. Prices range from $30 to $60 per month for these plans if you choose the no term agreement option. Certain areas also have access to Gig-speed internet, Xfinity’s ultra-fast fiber internet option. Gig-speed offers download speeds up to 2,000 Mbps — but it’s less accessible and much more expensive than traditional cable internet. To see which plans are available in your area, use our ZIP check tool.

What Xfinity speed should I get?

The right internet speed for your household depends on how many devices you use, how often you’re on them, and what activities you primarily do on the internet. The table below can serve as a guideline to get you started. Once you’re signed up, we also recommend checking data usage in your Xfinity user account. This is a good way to ensure that you’re not in danger of exceeding data limits or paying for more speed than you actually need.

The speed provided by Xfinity will be determined by the plans offered in your area. Speeds range from 15 Mbps to 2,000 Mbps. Once you're signed up, use the Xfinity speed test tool to make sure you're getting the speeds you paid for, and check your data usage in your Xfinity user account.

What is the difference between Comcast and Xfinity?

There isn’t one. Xfinity is owned by Comcast — it’s the company’s cable TV, internet, and phone branch. The two names are sometimes used interchangeably when talking about these services. You may also see it called “Comcast Xfinity” or “Xfinity by Comcast.” All names refer to the same suite of TV, phone, and internet services provided by Comcast.

The Bottom Line

The first step in choosing an ISP is to see which companies are available in your area and to compare plans and pricing offered by those companies. If Xfinity has service where you live, then it’s likely one of your best options. With multiple speed tiers, decent value, and certified reliability, Xfinity tops much of the competition. And while customer support has been a sticking point for the company, efforts to improve its service point toward a more positive customer experience in the future.
