The Deco X50 is positioned as a solid mesh solution with good throughput and coverage, but under real-world load its latency behavior reveals a gap that significantly impacts user experience.

When the network is saturated (uploads, downloads, or mixed traffic), bufferbloat becomes evident: latency spikes, jitter increases, and interactive applications degrade (gaming, VoIP, video calls). Raw bandwidth is not the problem here—queue management is.

Request: Implement SQM (e.g., fq_codel or CAKE) on the WAN interface.

Why this matters:

• Maintains low and stable latency under load

• Prevents bufferbloat without requiring manual traffic shaping hacks

• Improves fairness across devices and flows

• Brings the Deco line closer to prosumer-grade network behavior

Current QoS options are insufficient—they prioritize but do not control queue depth effectively. SQM operates at a lower level and solves the root issue rather than masking it.

Given the hardware capabilities of the X50, this is a firmware-level improvement that would meaningfully elevate the product without requiring new hardware.

If implementation constraints exist (CPU overhead, etc.), even a simplified SQM mode with user-defined bandwidth caps would be a major improvement.

This feature would directly translate into better real-world performance, especially in households with multiple active users.

Please consider adding SQM in a future firmware update.
