Our internet connections are increasingly becoming the lifeblood of our households. Whether you're working from home, taking extra online courses, streaming The Last of Us or overhauling your place with all the best smart home devices, your internet service provider is almost as important as your gas, water and electricity suppliers. What's one of the best ways to ensure your ISP delivers on its promises? Run a speed test.

A speed test will give you a snapshot of the megabits-per-second download and upload speeds you're getting from your provider. There are severalgood internet speed testsout there you could use. If you're a Comcast Xfinity customer, in particular, Xfinity boasts its own speed test, available at But as I delve more specifically into Xfinity speed test results, this page will largely reflect data from It's the tool from Ookla, which quarterly publishes the results gathered from millions of customer uses of its speed test.

Where did Xfinity speed test results place it among the top US internet providers?

For the first quarter of 2023, Xfinity fell from the top spot among the country's biggest ISPs. It landed just short ofSpectrum, which held the pole position midway through 2022.

Fastest internet providers in the US

Provider Median download speed
Spectrum 235Mbps
Xfinity 233Mbps
Cox 219Mbps
Optimum 196Mbps
Frontier 190Mbps
Verizon 186Mbps
AT&T Internet 180Mbps

In order to qualify as one of the country's top internet providers, an ISP must appear in 3% or more of the total test data taken during the three-month period. For example, EPB, a provider in Chattanooga, Tennessee, boasts the country's fastest residential internet plan at 25 gigabits per second. But since it's only available in that portion of the country, it won't show up on the national list (though it certainly registered in the state of Tennessee).

Also of note, that 3% threshold is based on the data taken from tests run by customers across the country, not simply whether a provider covers 3% of the country. T-Mobile Home Internet, for example, is now available to 89% of the country, according to the Federal Communications Commission's National Broadband Map. However, its customer base, which has grown to over 3 million subscribers, was not quite large enough for it to crack into consideration on that top list.

Does that mean every Xfinity customer will get 233Mbps?

Though Xfinity speed test results with Ookla garnered it a median download speed rating of 233Mbps, that doesn't equate to every Xfinity subscriber getting at least 233Mbps. But it does show that most Xfinity customers will have a consistent internet experience. In fact, Ookla has a "Consistency" ranking -- which shows the percentage of results that registered above broadband speed (25Mbps download and 3Mbps upload) -- and Xfinity landed near the top of that chart also with a 91.7% rating.

That can also be combined with the FCC's recent findings that over 90% of participants experienced actual median download speeds that were at least 95% of the ISP's advertised download speed. That's certainly another good way to determine consistency for the customer. But what are the advertised speeds offered by Xfinity?

Available internet speeds from Xfinity

Most ISPs offer three to five speed tiers, but Xfinity is unique in that it boasts seven to eight different internet speed options, depending on your location. That's quite a bit more choice for customers than one normally encounters.

Xfinity speed tiers

Plan Max speeds
Connect 75Mbps download, 10Mbps upload
Connect More 200Mbps download, 10Mbps upload
Fast 400Mbps download, 10Mbps upload
Superfast 800Mbps download, 20Mbps upload
Gigabit 1,000Mbps download, 20Mbps upload
Gigabit Extra 1,200Mbps download, 35Mbps upload
Gigabit X2 2,000Mbps download, 50Mbps upload
Gigabit Pro 6,000Mbps download, 6,000Mbps upload

Brian L. Roberts, chairman and CEO of Comcast,said during a January earnings call that Gigabit Plus customers comprise roughly one-third of Xfinity broadband subscribers. That's a bit higher thanOpenVault's latest data for internet customers across the US, which has gigabit (and above) consumption at 15%. Overall, according to OpenVault, most customers (55%) opt for a plan of 200-400Mbps. The rest of the data shows 10% go with 100-200Mbps, 8% are in the 50-100Mbps category, 7% choose 500-900Mbps and 5% are on plans under 50Mbps.

For Xfinity, all plans are a hybrid fiber-coaxial cable connection, so customers' download speeds will be much faster than their upload speeds. The one exception is the Gigabit Pro plan, which is a 100% fiber connection. While it's theoretically available throughout Xfinity's national footprint, FCC numbers indicate it's only available to approximately 4% of Xfinity's customer base.

US states where Xfinity was the top ISP

State Median download speed
Arizona 237Mbps
Colorado 245Mbps
Delaware 237Mbps
Kentucky 245Mbps
Massachusetts 227Mbps
Michigan 237Mbps
New Hampshire 240Mbps
New Mexico 233Mbps
Oregon 236Mbps
Pennsylvania 231Mbps
Washington 237Mbps

Comcast's Xfinity internet service is available in 39 states and the District of Columbia, so that gives it a decent chance at grabbing the top spot in a number of states. It had the slowest showing in Massachusetts at 227Mbps and its fastest download speed at 245Mbps in both Colorado and Kentucky.

US cities where Xfinity was the top ISP

City Median download speed
Albuquerque, New Mexico 238Mbps
Aurora, Colorado 260Mbps
Baltimore, Maryland 209Mbps
Colorado Springs, Colorado 255Mbps
Denver, Colorado 232Mbps
Fort Wayne, Indiana 203Mbps
Fremont, California 207Mbps
Fresno, California 248Mbps
Memphis, Tennessee 185Mbps
Miami, Florida 202Mbps
Portland, Oregon 218Mbps
Sacramento, California 233Mbps
San Jose, California 237Mbps
Seattle, Washington 217Mbps
St. Paul, Minnesota 215Mbps
Stockton, California 244Mbps
Tucson, Arizon 245Mbps

As for city speeds, the Ookla data takes into account only the top 100 most populous cities in the country. On that list, Xfinity was the fastest provider in 17 cities, which again put it in second place to Spectrum, which grabbed the top spot in 18 US cities. Memphis, Tennessee, brought up the rear for Xfinity, with a median download speed of 185Mbps (that also put it at the very bottom of the list of the top 100 US cities). Xfinity scored its fastest median download speed in Aurora, Colorado, with 260Mbps.

Xfinity speed test: Final thoughts

If you've read any of CNET's home internet coverage, you've heard us say that fiber internet trumps cable internet in just about every way. That's certainly true. But most fiber ISPs with a large national footprint -- , CenturyLink, Frontier, Optimum and Verizon -- don't exclusively offer fiber internet plans. Their coverage areas also include a mix of slower connection types like digital subscriber line. The speed test results in those areas will be significantly lower than the fiber numbers, thus making the providers' total numbers lower. But Xfinity, and other cable internet providers that don't have to deal with DSL dragging down their numbers, will see a much more consistent performance across the country. In that way, cable trumps the fiber-DSL combo.

Xfinity Speed Test FAQs

Why should I bother to run an Xfinity speed test?

If you feel like your internet connection is performing poorly, running a speed test is one of the quickest ways to see if you're getting the speed your ISP advertised. If you are getting the internet speed you're paying for, then perhaps your struggles mean you need to upgrade to a faster plan. But if your speed test results show speeds below what you should receive, then further investigation is warranted. It could be an issue with your provider (especially if you ran the test while connected via ethernet cable), or you may have uncovered some problems with your Wi-Fi connection.

How fast is Xfinity's cheapest plan?

Xfinity is unique in that it offers at least seven different speed tiers. On top of that, it has different pricing for those plans depending on the area of the country in which you're located. In some areas of the country, the cheapest plan is a 400Mbps plan; in others, the cheapest is its 75Mbps option. Finally, Xfinity also offers a low-income option, Internet Essentials, for eligible customers. That plan is 50-100Mbps.

What is a good speed for Xfinity?

During a recent earnings call, Comcast executives noted that nearly one-third of its customer base subscribes to its 1,200Mbps plan. That said, Xfinity speed test data from Ookla shows that Xfinity's median download speed is 233Mbps, and recent data from OpenVault shows that most US subscribers (approximately 55%) receive 200-400Mbps. Ultimately, a "good speed" depends on the needs of your household. The more users (and connected devices) you have, the greater your need for a higher internet speed tier.
