In 2026, the Deco X90 mesh Wi-Fi system has become a popular choice for households seeking high-speed internet coverage. Its performance varies depending on the size and layout of the home. This article presents the latest speed test results across different home sizes, providing insights into the Deco X90's capabilities.

Overview of Deco X90

The Deco X90 is a tri-band Wi-Fi 6E mesh system designed to deliver fast and reliable internet throughout large and complex homes. It features multiple units that work together to eliminate dead zones and support multiple devices simultaneously. Its advanced technology ensures high throughput and low latency, making it suitable for gaming, streaming, and smart home applications.

Speed Test Methodology

Speed tests were conducted using a standardized protocol across various home sizes. Each home was equipped with a Deco X90 system, and tests were performed using a high-performance laptop connected via Ethernet to the main router unit. Speed measurements were taken at multiple points within each home to assess coverage and performance.

Results in Small Homes (up to 1,000 sq ft)

In small homes, the Deco X90 delivered impressive speeds, often exceeding 900 Mbps on the main floor. Signal strength remained consistent throughout, with minimal dead zones. The system effectively handled multiple devices streaming 4K content and online gaming without noticeable lag.

Results in Medium Homes (1,000 - 2,500 sq ft)

For medium-sized homes, the Deco X90 maintained high speeds, averaging around 700-800 Mbps in central areas. Some peripheral rooms showed slight drops, but overall coverage was strong. The system's mesh capability ensured seamless connectivity as devices moved between zones.

Results in Large Homes (2,500 - 4,000 sq ft)

In larger homes, the Deco X90's performance depended heavily on the placement of units. When properly configured with multiple units, speeds remained above 500 Mbps in most areas. Without optimal placement, some zones experienced reduced speeds and increased latency, highlighting the importance of strategic placement in large spaces.

Results in Very Large Homes (over 4,000 sq ft)

In very large homes, the Deco X90 system required multiple units spaced evenly to achieve satisfactory coverage. Even then, some distant zones saw speeds drop below 300 Mbps. Users reported occasional buffering during high-demand activities in the most remote areas, indicating limitations in coverage without extensive node deployment.

Conclusion

The Deco X90 demonstrates excellent performance in small to medium-sized homes, providing fast, reliable Wi-Fi coverage. In larger residences, optimal placement and multiple units are crucial to maximize speeds and coverage. Overall, it remains a top choice for users seeking a high-performance mesh Wi-Fi system in 2026.
