Not all internet is created equal. Sometimes, those fast internet speeds on paper don’t always match expectations in practice. If your internet connection drops in the middle of a video call or your stream buffers right as the game goes to overtime, those specs don’t mean too much. What really matters for everyday internet users is how your internet performs in the real world, during the moments that count.
In its May 2026 U.S. Fixed Broadband Experience Report, Opensignal set out to determine which internet providers delivered for users, conducting an independent analysis of the real-world performance of the five largest internet providers in the country across five key categories. The verdict? Xfinity ranked #1 nationally in three of the five: Consistent Quality, Download Speed, and Video Experience.
Here’s a look at what those wins mean for you.
Consistent Quality: What is it and how is it measured?
Consistent Quality is one of the most meaningful ways to evaluate an internet connection because it measures reliability at the task level—not just in ideal conditions, but across everything you’re actually doing online. According to Opensignal, Consistent Quality tracks how well a network meets the requirements for common applications from the perspective of a single device, once connectivity is established.
To determine a score, Opensignal evaluates six performance indicators: download speed, upload speed, latency, jitter, packet loss, and time to first byte. Thresholds are set to reflect individual (not multi-device) usage, and the metric captures the percentage of tests that meet those thresholds across all hours of the day. In practical terms, that means Consistent Quality reflects whether your connection is up to the task when you’re on a group video call, uploading photos to social media, controlling smart home devices, or gaming online.
Xfinity earned the top national ranking in this category, edging out second-place Verizon. That result reflects not just peak performance, but steady, dependable quality across the network—the kind of connection that doesn’t let you down when it matters.
Download Speed: Fast when you need it
Download speed is the metric most people think of first, and for good reason—it affects nearly everything. Streaming in 4K, downloading large files, loading web pages, running cloud-based apps. Most online activity relies on how quickly data can travel from the internet to your devices.
Opensignal defines Broadband Download Speed as the typical everyday speeds a user experiences across a provider’s network, measured in Mbps. It’s not a theoretical maximum or a laboratory result. It’s what real users actually get, drawn from billions of measurements collected across devices during use.
Xfinity ranked #1 in this category nationally, outpacing Spectrum, which came in second. The win reflects the strength of the Xfinity network infrastructure, including ongoing DOCSIS upgrades that have contributed to a 20% increase in upload speeds year over year. Faster uploads are an added benefit, further narrowing the performance gap between cable and fiber networks.
Video: Streaming without the struggle
Streaming is now a daily habit for most households, whether it’s a movie night, catching a live game, or keeping the kids entertained with their favorite shows. So it’s no surprise that Video Experience is one of the most consumer-relevant metrics in the Opensignal report.
Opensignal’s Video Experience score measures how well a connection handles streaming quality across three dimensions: start times (how quickly content begins playing), resolution (whether you’re watching in HD or something less impressive), and buffering performance (how often playback is interrupted while the video loads).
Xfinity came in first nationally in this category, reflecting how consistently strong Xfinity Internet performs for streaming. Notably, the report found that all five major ISPs scored in the “Very Good” range for Video Experience, meaning users across the board were able to stream at 1080p or better with satisfactory loading times and minimal stalling.
One more win: Most reliable WiFi in head-to-head comparisons
Beyond the national rankings, Opensignal also conducted head-to-head comparisons—pitting providers against each other only in the geographic areas where they directly compete. In those matchups, Xfinity earned its second consecutive win for Most Reliable WiFi, reinforcing that the network’s strength isn’t just a national average—it holds up locally, too.
Independent Data. Real-World Results.
Opensignal is one of the most respected independent broadband research firms in the world. The May 2026 report analyzed data collected between January and March 2026, drawing on billions of real measurements from actual user devices—not controlled tests or self-reported surveys. When an independent organization with that methodology ranks your network #1 in three categories, it means something.
