Indoor Wi-Fi Roaming with OpenWRT

A home network running OpenWRT has significantly improved Wi-Fi roaming performance by deploying uSteer and static neighbor reports, enabling more reliable client handoff between access points without vendor-specific software.

The user operates a dual-band setup with separate SSIDs for 2.4GHz and 5GHz, maintaining legacy support for IoT devices on WPA2 and modern devices on WPA3. Despite enabling 802.11r/k/v and fast transition, clients often remained anchored to distant APs. The user identified that hostapd was not exposing neighbor reports, which hindered client steering. By installing uSteer and static neighbor reports on all four APs, they configured each to advertise only relevant peers per band, resulting in improved roaming behavior. Post-implementation, data showed better signal quality and more balanced client distribution across APs, especially on the 5GHz band, with noticeable shifts in client connection patterns.

Why It Matters

This development matters because it demonstrates a DIY method to enhance Wi-Fi roaming in a home environment without relying on proprietary vendor solutions. Better roaming reduces dead zones, improves device performance, and extends the usability of existing hardware, making advanced Wi-Fi management accessible to enthusiasts and small-scale setups.

Background

OpenWRT is a popular open-source firmware for routers, allowing extensive customization. While basic roaming features exist, their effectiveness varies, especially in complex home layouts. Previous efforts often relied on vendor-specific features; this approach leverages open-source tools like uSteer and neighbor reports to fill that gap. The user’s experience highlights ongoing challenges with cross-band roaming and client behavior, which remain partially unresolved but significantly improved through these configurations.

“Adding uSteer and static neighbor reports made a noticeable difference in client roaming, with devices switching more reliably between APs.”

What Remains Unclear

It remains unclear how well this setup performs over longer periods or in more congested environments, and whether cross-band roaming can be further improved with additional configurations. Client device behavior, especially with Apple products, continues to influence results and may vary depending on hardware and firmware versions.

What’s Next

Further testing is expected to refine neighbor report configurations, explore cross-band roaming improvements, and evaluate long-term stability. The community may develop more integrated solutions or scripts to automate these setups, expanding accessibility for other OpenWRT users.

Key Questions

Can this setup work with all Wi-Fi clients?

Most modern 802.11k/v capable clients should benefit, but some devices, especially Apple products, may still have limited roaming behavior due to client-side implementation.

Do I need to use separate SSIDs for each band?

Yes, in this setup, separate SSIDs are maintained for 2.4GHz and 5GHz to allow band-specific neighbor reports and control over roaming behavior.

Is this approach suitable for large or enterprise networks?

This method is primarily designed for home or small-scale setups. Larger networks may require more sophisticated solutions or vendor-specific features.

What hardware is needed to implement this?

Any router compatible with OpenWRT that supports hostapd, uSteer, and static neighbor reports can be used. The user’s example involved Cudy AX3000 units.
