Our internet connections are increasingly becoming the cornerstone of our homes. That you are work from hometake additional online courses, stream The last of us or the redesign of your place with all the best smart home devicesyour internet service provider is almost as important as your gas, water and electricity suppliers. What’s one of the best ways to make sure your ISP keeps its promises? Run a speed test.

A speed test will give you an overview of the download and upload speeds in megabits per second that you are getting from your provider. There are many good internet speed tests there you could use. If you are a Comcast Xfinity customer, in particular, Xfinity offers its own speed test, available at But since I’m looking more specifically at Xfinity speed test results, this page will largely reflect data from It is the tool of Ookla, which publishes quarterly the results collected from millions of users using its speed test.

Where did Xfinity’s speed test results place it among the top US ISPs?

For the first quarter of 2023, Xfinity has fallen from the top spot among the largest ISPs in the country. He landed just before Spectrumwho held pole position in the middle of 2022.

The Fastest Internet Service Providers in the United States

AT&T Internet180Mbps

In order to qualify as one of the top ISPs in the country, an ISP must appear in 3% or more of the total test data taken during the three month period. For example, PEB, a provider in Chattanooga, Tennessee, offers the nation’s fastest home internet plan at 25 gigabits per second. But since it’s only available in that part of the country, it won’t appear on the national list (although it’s certainly registered in the state of Tennessee).

It should also be noted that this 3% threshold is based on data from customer testing across the country, not simply that a provider covers 3% of the country. T-Mobile Home Internet, for example, is now available in 89% of the country, according to the Federal Communications Commission’s National Broadband Map. However, his customer base, which grew to over 3 million subscribers, was not large enough to be considered in this list.

Ookla speed test information does not use the mean (or average) of its data set, but the median, aiming to better represent the typical customer experience.

Ok so

Does this mean that every Xfinity customer will get 233 Mbps?

Although Xfinity speed test results with Ookla gave it a median download speed of 233 Mbps, that doesn’t equate to every Xfinity subscriber getting at least 233 Mbps. But it shows that most Xfinity customers will have a consistent internet experience. In fact, Ookla has a “Consistency” ranking – which shows the percentage of results recorded above broadband speed (25 Mbps download and 3 Mbps upload) – and Xfinity landed near the top of that chart as well with a score of 91.7%.

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

Internet speeds available on Xfinity

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

Brian L. Roberts, president and CEO of Comcast, said on a January earnings call that Gigabit Plus customers make up about a third of Xfinity broadband subscribers. That’s a bit higher than OpenVault’s latest data for US internet customers, which has 15% gigabit (and above) consumption. Overall, according to OpenVault, most customers (55%) opt for a 200-400 Mbps plan. The rest of the data shows that 10% opt for 100-200 Mbps, 8% are in the 50-100 Mbps category, 7% choose 500-900 Mbps and 5% are on plans below 50 Mbps.

For Xfinity, all plans are a hybrid fiber-coax connection, so customers’ download speeds will be much faster than their upload speeds. The only exception is the Gigabit Pro plan, which is a 100% fiber connection. While theoretically available across Xfinity’s nationwide footprint, FCC figures indicate it’s only available to about 4% of Xfinity’s customer base.

US states where Xfinity was the first ISP

Comcast’s Xfinity internet service is available in 39 states and the District of Columbia, giving it a decent shot at grabbing the top spot in a number of states. It had the slowest streaming in Massachusetts at 227 Mbps and its fastest download speed at 245 Mbps in Colorado and Kentucky.

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

Xfinity Speed ​​Test: Final Thoughts

If you’ve read any of CNET’s home internet coverage, you’ve heard us say that fiber internet assets Cable Internet in just about every way. It is certainly true. But most fiber ISPs with a large national footprint — AT&T, CenturyLink, Border, Optimum And Verizon — do not exclusively offer fiber internet packages. Their coverage areas also include a mix of slower connection types like digital subscriber line. Speed ​​test results in these areas will be significantly lower than fiber counts, reducing the total number of providers. But Xfinity, and other cable ISPs that don’t have to deal with DSL driving their numbers down, will see much more consistent performance across the country. This way, cable trumps the fiber-DSL combo.

Xfinity Speed ​​Test FAQ

Why should I bother running an Xfinity speed test?

If you feel like your internet connection is malfunctioning, performing a speed test is one of the quickest ways to see if you’re getting the speed your ISP claims. If you’re getting the internet speed you pay for, your struggles may mean you need to upgrade to a faster plan. But if your speed test results indicate lower speeds than you should be receiving, further investigation is warranted. It could be an issue with your provider (especially if you ran the test while connected via an Ethernet cable) or you may have discovered issues with your Wi-Fi connection.

How fast is Xfinity’s cheapest plan?

Xfinity is unique in that it offers at least seven different speed levels. In addition to that, it has different prices for these packages depending on which region of the country you are in. In some parts of the country, the cheapest plan is a 400 Mbps plan; in others, the cheapest is its 75 Mbps option. Finally, Xfinity also offers a low-income option, Internet Essentials, for eligible customers. This plan is 50 to 100 Mbps.

What is a good speed for Xfinity?

In a recent earnings call, Comcast executives noted that nearly a third of its customer base subscribed to its 1,200 Mbps plan. That said, Xfinity speed test data from Ookla shows the median download speed of Xfinity to be 233 Mbps, and recent data from OpenVault shows that most US subscribers (around 55%) receive 200-400 Mbps. Ultimately, a “good speed” depends on the needs of your household. The more users (and connected devices) you have, the higher level of internet speed you need.
