Where do Xfinity's speed test scores rank among the top US ISPs?

For the first quarter of 2023Xfinity has fallen from the number one spot among the largest Internet service providers in the country. He landed a little earlierSpectrum, who held pole position in mid-2022.

Fastest Internet Service Providers in USA

Giver Average download speed
Spectrum 235 Mb/s
Xinfinity 233 Mb/s
Helmsman 219 Mb/s
Optimum 196 Mb/s
Border 190 Mb/s
Verizon 186 Mb/s
Internet AT&T 180 Mb/s

To qualify as one of the country's leading ISPs, an ISP must appear in at least 3% of all test data collected over a three-month period. For example,EPB, a Chattanooga, Tennessee-based provider, boasts the country's fastest 25 gigabit-per-second household Internet access plan. 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 Tennessee).

It's also important to note that this 3% threshold is based on customer test data across the country, not just whether the provider covers 3% of the country.Tmobile home internet, for example, is now available in 89% of the country, according to the Federal Communications CommissionNational broadband map. However, the user base, which has grown to over 3 million subscribers, was not large enough to be included on this list.

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

While Xfinity's speed test results from Ooklo gave an average download speed of 233Mbps, that doesn't mean that every Xfinity subscriber is getting at least 233Mbps. But it shows that most Xfinity users will have a consistent online experience. In fact, Ookla has a "Consistency" ranking - which shows the percentage of scores recorded above broadband speed (25Mbps download and 3Mbps upload) - and Xfinity also landed near the top of that ranking with 91.7%.

It can also be combined withRecent FCC disclosuresthat over 90% of participants experienced an actual average download speed that was at least 95% of the download speed advertised by their ISP. Certainly, this is another good way to define consistency for the client. But what are the advertised speeds offered by Xfinity?

Internet speeds available from Xfinity

Most ISPs offer three to five levels of speed, but Xfinity is unique in that it offers seven to eight different internet speed options, depending on your location. It's a little more choice for customers than usual.

Xfinity of speed levels

Plan Max speed
To combine 75 Mb/s download, 10 Mb/s upload
Connect more 200 Mb/s download, 10 Mb/s upload
Quick 400 Mb/s download, 10 Mb/s upload
Super fast 800 Mb/s download, 20 Mb/s upload
Gigabit 1000 Mb/s download, 20 Mb/s upload
Gigabit addition 1200 Mb/s download, 35 Mb/s upload
Gigabit X2 2000Mbps download, 50Mbps upload
Gigabit Pro 6000Mbps download, 6000Mbps upload

Brian L. Roberts, president and CEO of Comcast,he said during an earnings call in Januarythat Gigabit Plus customers account for approximately one-third of Xfinity broadband subscribers. It's a little more than thatThe latest OpenVault datafor Internet users in the entire US, whose gigabit (and above) usage is 15%. Overall, according to OpenVault, the majority of customers (55%) opt for a 200-400Mbps plan. Other figures show that 10% choose 100-200Mbps, 8% fall into the 50-100Mbps category, 7% choose 500-900Mbps, and 5% have plans below 50Mbps.

With Xfinity, all plans are hybrid fiber and coax connections, so users' download speeds will be much faster than their upload speeds. The only exception is the Gigabit Pro plan, which is 100% optical. Though theoretically available nationwide Xfinity,FCC numbersshow it's only available to about 4% of Xfinity's customer base.

US states where Xfinity was the leading ISP

Michigan 237 Mb/s
New Hampshire 240 Mb/s
New Mexico 233 Mb/s
Oregon 236 Mb/s
Pennsylvania 231 Mb/s

Comcast's Xfinity internet service is available in 39 states and the District of Columbia, giving it a decent chance of taking the top spot in many states. The slowest was in Massachusetts at 227 Mbps, and the fastest download speed was 245 Mbps in Colorado and Kentucky.

U.S. cities where Xfinity was the top ISP

Grad Average download speed

St. Paul, Minnesota 215 Mb/s
Stockton, California 244 Mb/s
Tucson, Arizona 245 Mb/s

When it comes to city speeds, Ookla's figures only count the 100 most populous cities in the country. On this list, Xfinity was the fastest provider in 17 cities, which again placed it in second placeSpectrum, which took first place in 18 US cities. Memphis, Tennessee leads the Xfinity, with an average download speed of 185 Mbps (which also places it at the bottom of the top 100 US cities list). Xfinity achieved the highest average download speed in Aurora, Colorado at 260 Mbps.

Xfinity Speed ​​Test: Final Thoughts

If you've read any of CNET's home web coverage, you've heard us say itoptical internetadvantagesCable internetjust fine in every way. This is certainly true. However, most fiber ISPs with a large national reach --,Century Link,Border,OptimumIVerizon- do not offer fiber-only plans. Their coverage areas also include a mix of slower connection types such asdigital subscriber line. The speed test results in these areas will be much lower than the fiber numbers, making the overall number of providers lower. But Xfinity and other cable providers that don't have to deal with DSL throttling will see much more consistent performance across the country. In this way, the cable outperforms the fiber-DSL combination.

Xfinity Speed ​​Test FAQ

Why would I bother to run the Xfinity Speed ​​Test?

If you feel your internet connection isn't working well, running a speed test is one of the quickest ways to see if you're getting the speeds advertised by your ISP. If you're getting the internet speed you're paying for, perhaps your difficulties mean you need to upgrade to a faster plan. But if your speed test results show speeds below what you should be getting, further investigation is warranted. It may be a problem with your service provider (especially if you ran the test with an ethernet cable connection) or you found problems with your Wi-Fi connection.

How fast is the cheapest Xfinity plan?

Xfinity is unique in that it offers at least seven different speed levels. In addition, there are different prices for these plans depending on the area of ​​the country you are in. In some parts of the country, the cheapest plan is the 400Mbps plan; in others, the cheapest option is 75 Mb/s. Finally, Xfinity also offers a low-income option, Internet Essentials, for eligible customers. This plan is 50-100Mbps.

What is a good speed for Xfinity?

During a recent earnings call, Comcast executives noted that nearly a third of their customer base is subscribed to a 1200Mbps plan. However, Xfinity speed test data from Ookla shows that Xfinity's average download speed is 233 Mbps, and recent data from OpenVault shows that the majority of US subscribers (around 55%) are getting 200-400 Mbps. Ultimately, "good speed" depends on the needs of your household. The more users (and connected devices) you have, the more you need a higher level of internet speed.
