The Results Are In: Xfinity Ranks Best for Consistent Quality & Download Speeds

The Opensignal “USA, Converged Experience Report” is the first of its kind, evaluating the experience of U.S. customers who bundle their mobile and home internet services with the same provider. Converged experience refers to the combined network performance that a customer receives across both cellular and Wi-Fi connections when bundling mobile and home internet services with the same provider.

Opensignal is an independent mobile analytics company that specializes in quantifying the consumer network experience, providing comprehensive data on network coverage and performance. The research and data they publish helps inform consumers and allows for benchmarking of mobile operators worldwide.

This new report, published in April 2026, focuses on convergence, or using the same company for both mobile and broadband services. Convergence is quickly becoming an important strategy across major providers, and this research helps distinguish these providers across key metrics.

When networks start to look similar in terms of products and performance, user experience becomes an important way for providers to stand out from the competition. This report analyzes three critical areas of the converged user experience—consistent quality, download speed and upload speed.

The results? Xfinity leads in both consistent quality (83.9 percent) and download speed (247.1 Mbps), while AT&T takes first in upload speed (109.0 Mbps). If you’ve been considering a new provider, or combining your mobile and home internet services, the findings from this report can be a useful tool for your research.

Quick Comparison: Overall Combined Experience Rankings

We’ll dive deeper into these numbers later, but here’s a quick overview of the report’s findings, showing where each provider ranked for consistent quality, download speed and upload speed.

Key Definitions

Here’s a breakdown of some of the specific terms you’ll see throughout this report:

• Consistent Quality: The percentage of tests that met minimum performance thresholds to support HD video streaming, group video conference calls and online gaming.
• Download Speed: The typical everyday speeds (measured in megabits per second, or Mbps) that users experienced across mobile and fixed broadband connections, necessary for streaming, browsing and downloading.
• Upload Speed: The average upload speeds (measured in Mbps) that users experienced across mobile and fixed broadband connections, necessary for video conferencing, online gaming and uploading files. 

Background Info

Convergence is becoming a hot topic among U.S. telecom providers—and it’s driven by two trends:

• Customers expect a seamless connection experience across both cellular and Wi-Fi.
• There are limited growth opportunities for service providers—the growth rate of mobile subscriptions was just two percent in 2025, and 90 percent of households already have broadband.

As a result, companies have turned their focus to finding strategies that attract more customers—and keep them. Convergence is noted for increased customer satisfaction, and as we know, happy customers tend to stick around for longer.

Cable and telecommunication providers have been moving quickly to bring convergence into their offerings.

Major cable companies Xfinity and Spectrum have been exploring convergence with mobile:

• Both Xfinity and Spectrum have pursued convergence via an agreement with Verizon for their consumer subscribers, and T-Mobile for business wireless offerings.
• Both companies are exploring ways to reduce mobile data costs, including Wi-Fi offload (aka: shifting mobile data traffic from cellular networks to Wi-Fi networks to reduce congestion) and other strategies.
• Xfinity’s infrastructure investments show up. Built on an advanced fiber-optic network, they provide reliable, ultra-fast internet with the low latency and high bandwidth required to support the growing needs of consumers’ homes.
• Both companies offer great deals when you bundle internet and mobile. As a new customer, you can bundle Xfinity’s reliable home Wi-Fi with Xfinity Mobile for nationwide 5G coverage. When you sign up for Xfinity home internet, your first Xfinity Mobile Select line is included for a full year. This combination provides wall-to-wall home coverage and 5G data on the go.

Meanwhile, telecommunications companies are starting to build out their broadband offerings:

• AT&T has shifted to focus on convergence, increasing their investment in expanding fiber and wireless offerings.

• Major telecom providers are acquiring fiber companies to get the infrastructure they need to move into the convergence space. Verizon acquired Frontier for fiber and Starry, which provides FWA in multi-dwelling units like apartments and condos. AT&T acquired Lumen for fiber and EchoStar for FWA. And T-Mobile acquired both Metronet and Lumos to enter into the fiber market.

Methodology

• Opensignal analyzed the five largest U.S. providers—AT&T, Spectrum, T-Mobile, Verizon and Xfinity—with data collected from converged users between January 1 and March 31, 2026.
• The analysis measured the experience of consumers who purchase broadband and mobile from the same provider, capturing performance across both cellular and Wi-Fi connections—this is what Opensignal calls the “combined experience” for each of their metrics.
• Plan characteristics, such as speed tiers or data caps, vary widely from provider to provider and have an impact on the average experience result. However, for the purpose of this report, Opensignal’s measurements capture users’ real-world experiences, regardless of which plan they are on, painting a clear picture of performance across all users’ plans.
• The metrics in this report (consistent quality, download speed and upload speed) account for the different ways to access a given broadband type, including 4G, 5G, satellite and coaxial cable networks. Newer technologies will generally perform better than older ones, but the results in this report include the experiences of users from both ends of the spectrum.

Overall Rankings

As we mentioned, the five largest providers were ranked according to consistent quality, download speed and upload speed.

So how did each company stack up? Let’s take a look.

Overall Combined Experience

Overall combined experience compares results across the key metrics, regardless of broadband connection type. In a later section of the report, we’ll see how each of these companies rank for the specific connection type they offer, including fiber, cable and FWA.

Xfinity tops the leaderboard for consistent quality with 83.9 percent, with a short lead over Verizon, who came in second place with 83.4 percent. This was a close category overall, with only a small margin between first place (83.9 percent) and fifth place (81.4 percent).

Consistency is key when it comes to Wi-Fi, and Xfinity delivers worry-free Wi-Fi with their advanced Gateway technology that optimizes network traffic, helping eliminate dead spots and reducing buffering during high-bandwidth activities.

Xfinity also wins for download speed experience, with a score of 247.1 Mbps. That’s a 7 Mbps lead over Spectrum, who came in second place with 240.1 Mbps. AT&T is a close third with 233.3 Mbps.

In the category of upload speed experience, AT&T came in on top with 109.9 Mbps, more than double the speed of Verizon, who came in second. However, second and third place are much closer, with Verizon at 48.0 Mbps and Xfinity at 47.1 Mbps. For reference, upload speeds between 10 Mbps and 20 Mbps is sufficient for most average households.

How Broadband Connection Affects Combined Experience

Users that participated in this report spent more than 65 percent of their time on Wi-Fi, which shows that broadband connection type has a big impact on a user’s combined experience. 

This next section of the report includes a breakdown of Opensignal’s data that looks at converged experience across the main types of broadband connections: fiber, cable and FWA. Less-popular connection types, such as DSL and satellite, were not included in this report.

As you’ll see below, Xfinity’s connection type is listed as cable, but primarily uses a hybrid fiber-coaxial (HFC) network, which employs fiber optic cable for the connection between the provider and a node in your neighborhood, and coaxial cable to bring the connection from the node into your home. While Xfinity has limited fiber-to-home networks, their HFC network is known for its performance, fast speeds and high reliability.

Consistent Quality Across Connection Types for Broadband

First up, let’s see how the five main providers rank for consistent quality by broadband connection type:

As you can see, only four percentage points separate first, second and third place in this category. First place is Verizon’s fiber connection with 87.9 percent, second is AT&T’s fiber connection with 85.2 percent and third is Xfinity’s cable connection with 83.9 percent. What this tells us is that fiber and cable deliver a similar level of consistent quality across providers.

Traditionally, fiber-to-the-home connections are deemed to be the best of the best. However, the results in this report challenge that notion, showing that Xfinity can meaningfully stack up against fiber competitors.

Previous research conducted by Opensignal showed that users with fiber and cable typically saw the highest speeds. And there is a similar trend in this report, with converged subscribers on fiber networks seeing a slightly better combined experience than those with cable, who in turn see slightly better results than those on FWA.

However, the data in this new report shows that for combined experience, FWA is able to deliver comparable results in some instances. Both T-Mobile and Verizon’s FWA ranks close to Spectrum’s cable service, all three coming in between 80.1 and 81.3 percent. However, AT&T’s FWA is considerably lower at 72.9 percent.

One other point to note is that providers that offer both fiber and FWA see a more noticeable difference between consistent quality scores. For instance, Verizon’s fiber ranks almost eight percentage points higher than their FWA service. And similarly, AT&T’s fiber ranks more than 12 percentage points higher than their FWA service.

Download Speed Across Connection Types

When we look at download speed experience, we start to see more significant differences between providers:

Converged users with AT&T fiber have the highest download speed, at 290.6 Mbps—37 Mbps faster than second place. However Xfinity comes in strong in second place—a cable connection with 253.2 Mbps, outperforming Verizon’s fiber connection in third place with a download speed of 248.6. Spectrum’s cable users are slightly behind Verizon fiber with 243.5 Mbps.

And then there’s a bigger drop to FWA providers—with T-Mobile leading the pack with 199.7 Mbps and Verizon and AT&T FWA more than 50 Mbps slower at 146.9 Mbps and 139.1 Mbps, respectively. T-Mobile’s significantly higher mobile speeds likely contribute to this result.

Upload Speed Across Connection Types

Upload speed shows an even greater separation between connection types, with fiber providers outperforming cable and FWA connections in this category:

Of the two fiber providers, AT&T outperforms Verizon with 161.2 Mbps compared to Verizon’s 102.3 Mbps upload speeds.

Cable providers deliver the next-highest upload speeds: Xfinity with 47.7 Mbps—that’s more than 11 percentage points higher than Spectrum’s 36.4 Mbps. Like we mentioned earlier, these speeds are more than sufficient for the average household. 

FWA providers follow a similar trend to what we saw with download speeds: T-Mobile’s FWA upload speeds are strongest with 28.8 Mbps, while AT&T and Verizon FWA offer the lowest upload speeds of 18.7 Mbps and 18.1 Mbps, respectively.
