The Fiber War in Spain Is No Longer Won Just by Increasing Speed

The Spanish fixed internet market has entered a phase where Mbps no longer tell the full story. The latest nPerf barometer on fixed connections in Spain, compiled from measurements taken between April 1, 2025, and March 31, 2026, shows a highly competitive landscape among MasOrange, Digi, Movistar, and Vodafone. The differences are increasingly in latency, web browsing, streaming, and the actual user experience.

MasOrange leads the overall ranking with 135,819 nPerf points, ahead of Vodafone, Movistar, and Digi. But the most striking data is Digi’s clear dominance in download and upload speeds, especially with FTTH fiber. This apparent contradiction neatly summarizes the market’s direction: having the fastest network doesn’t always translate to offering the best overall experience.

nPerf combines speed, latency, and quality of experience tests, such as web browsing and YouTube streaming. That’s why its final score does not reward just peak download speeds but the overall behavior of the connection. For users who telecommute, play online, watch videos, use video calls, and synchronize files in the cloud, this broader view is more useful than a simple speed test.

MasOrange leads in latency and balance

MasOrange scores the highest overall in the report with 135,819 points. Its advantage doesn’t stem from maximum speeds, where it falls behind Digi and Vodafone in downloads, but from a more stable combination of indicators. The provider records the best overall latency at 20.26 milliseconds and offers highly competitive web browsing and streaming performance.

In fixed connections, MasOrange achieves 291.94 Mbps download and 270.52 Mbps upload speeds. These are solid figures, though not the top of the leaderboard. Its strength lies in consistently delivering good results in areas that significantly impact daily quality perception.

Latency is becoming increasingly important because many applications no longer depend solely on downloading large volumes of data but require quick responses. Online gaming, remote desktops, video calls, SaaS tools, digital banking, productivity platforms, and cloud apps all benefit from connections with low and stable response times.

MasOrange’s leadership comes at a critical moment for the company. The integration of networks, brands, and customer bases following its group formation is one of the major processes in the Spanish telecom sector. Maintaining a high overall score in this context reinforces the idea that network quality will be a key variable in the new competitive phase.

Digi demonstrates that pure fiber continues to make a difference

If the overall ranking rewards balance, the FTTH category has a clear winner: Digi. The operator achieves 162,727 nPerf points with 597.36 Mbps download, 528.62 Mbps upload, and 16 ms latency. These are the best figures in the report for speed and response time within this technology.

From a technical perspective, it’s evident. Digi has built a very strong fiber position, with average speeds well above its competitors. In a market where many users are already contracting symmetric or high-capacity plans, upload speed has become as important as download speed.

This advantage impacts real-world usage. Uploading videos, working with code repositories, syncing large projects, backing up data, using cloud storage, or maintaining multiple simultaneous video calls increasingly depend on upload channels. In households with multiple users, symmetry and stability may outweigh promotional deals.

Digi’s challenge is translating this technical superiority into overall experience. Despite being the fastest, it ranks fourth in the global score. The report suggests its navigation and streaming metrics lag behind MasOrange, Movistar, and Vodafone. While this doesn’t diminish Digi’s strengths, it highlights that perceived quality depends on more than just the fiber access itself.

Vodafone and Movistar compete in daily experience

Vodafone ranks second overall with 132,390 points. Its performance is notable for improvements in upload speed and strong web browsing and streaming results. In the fixed connection set, it reaches 314.99 Mbps download—second only to Digi—and 231.00 Mbps upload.

The nPerf report also highlights Vodafone’s approximately 29% increase in upload speeds compared to the previous period. For a provider competing in a highly mature market, improving this metric is crucial as it better responds to evolving use habits: more cloud use, telecommuting, and user-generated content.

Movistar finishes third with 130,676 points. Its position remains stable, though it struggles with overall latency, at 28.03 ms—the worst among the four operators. However, in FTTH, it maintains competitive numbers: 483.08 Mbps download and 442.91 Mbps upload, surpassing MasOrange and Vodafone on fiber download speeds.

In FTTH streaming, Movistar achieves the best result with 90.17%. This is noteworthy because it reflects performance in typical daily use. Watching high-resolution videos without buffering or quality drops remains one of the most tangible indicators of user experience at home.

WiFi becomes the home’s bottleneck

The fixed network no longer ends at the router. In many homes, the real experience hinges on WiFi. The nPerf barometer includes a specific classification for wireless connections, where Digi and MasOrange are almost tied at the top.

Digi scores 133,791 WiFi points, with 258.22 Mbps download and 227.37 Mbps upload speeds. MasOrange achieves 132,619 points with the best WiFi latency at 21.20 ms. Movistar and Vodafone trail behind, with scores of 125,436 and 124,101 respectively.

This aspect is becoming increasingly important for operators. Fiber can offer hundreds of megabits, but if the router is poorly placed, walls are thick, interference occurs, or there are too many devices, the experience degrades. That’s why solutions like mesh WiFi systems, more capable routers, and remote diagnostic tools have become part of the commercial offering.

For users, the message is clear: getting good fiber is just part of the equation. The router quality, indoor coverage, and device management can radically change the perception of the connection.

A mature but unresolved market

Spain boasts one of the most extensive fiber networks in Europe, but the nPerf report shows there’s still room for differentiation. Operators are no longer competing solely on coverage or price—they now compete on experience, sustained performance, latency, and peak-hour quality.

nPerf analyzes tests conducted during peak hours (between 6:00 PM and 11:00 PM) as well as at other times of day. This detail is important because many networks appear excellent during low demand but reveal their limits when homes connect simultaneously to TVs, consoles, laptops, mobiles, and streaming services.

The test distribution also helps understand the sample. MasOrange accounts for 33% of tests, Movistar 27%, Digi 21%, and Vodafone 19%. nPerf only includes domestic operators with over 5% market share in testing, excluding smaller or regional players.

The final results do not offer a one-size-fits-all answer. MasOrange leads in overall balance. Digi is the strongest in speed and fiber technology. Vodafone remains competitive in browsing and video experience. Movistar maintains a robust fiber network with good streaming results but needs to improve latency to climb higher.

The next frontier in fixed connectivity in Spain will not only be about marketing. It will be technical. Users are beginning to notice the difference between a fast connection and a truly consistent one. Here, operators will need to look beyond headlines like “up to 1 Gb/s”: stability during peak hours, actual upload speeds, low latency, home WiFi, and quality of experience will become the new differentiators.
