Comcast is the fastest broadband ISP, and T-Mobile is the fastest wireless carrier, Ookla says

Comcast is the fastest broadband ISP in the United States, according to Ookla, the developer behind the popular website. Ookla also named T-Mobile as the fastest wireless carrier in the U.S.

Ookla found that Comcast Xfinity narrowly topped Verizon’s FiOS service as the fastest broadband ISP, while T-Mobile just edged out Verizon Wireless as the fastest wireless carrier. The data reflected 26 million unique broadband users, performing over 111 million tests across Ookla’s service. In the mobile space, about 3 million unique devices were used to generate 14 million tests, generating a comprehensive look at how each service performed both nationwide and over time.

In both wired and wireless tests, Ookla generated its own “speed score” to measure such factors as latency, and how the networks in question varied from region to region.


Who has the fastest broadband service? Comcast

In order, the fastest broadband ISPs are:

  • Comcast Xfinity
  • Verizon FiOS
  • Cox
  • Spectrum
  • AT&T Internet
  • Frontier 
  • CenturyLink

The most significant factor in increasing broadband speeds, Ookla found, was the transition to DOCSIS 3.1 modems, which helped boost speeds dramatically and made pricing innovations, such as a $69 gigabit package offered by Verizon, feasible.

What’s a “good” download speed? Well, according to Ookla, the average within the U.S. for the first and second quarters of 2017 was 64Mbps down, and 22.8Mbps up.

“These developments lead to direct improvements in speeds for individual ISPs and also spur the kind of competition that makes better, faster service available to more people,” Ookla found.

Comcast’s Xfinity also scored the highest when measuring what Ookla called “acceptable speed,” or the number of times that the available speed climbed above 10Mbps. That’s fast enough, according to Ookla, to stream HD video while someone else on the same connection can adequately access the Internet. Comcast delivered that level of service over 90 percent of the time.

Comcast may be the fastest overall, but in certain areas, other competitors prevailed. In Southern regions like Texas and Florida, you’ll want to buy broadband service from Suddenlink. In Midwestern regions like Chicago and St. Louis, Mediacom provides the fastest broadband service, according to Ookla. In fact, Ookla also looked at the “winners” in major metropolitan areas, and found that Spectrum was the fastest in 24 of them, topping both Cox (19) and Comcast (18).


Who has the fastest wireless service? T-Mobile

The average download speed by a wireless user was 22.69Mbps, according to Ookla—good, but just 44th in the world behind Fiji and Germany. Some of that is affected by the decreased speeds in rural areas, naturally.
