March 2026 focused on delivering robust Multi-Link Operation (MLO) support across the wifi stack, delivering both feature improvements and data-model enhancements that strengthen monitoring, management, and reliability of multi-link clients. Key work spanned rdk-wifi-hal (feature enhancement) and OneWifi (MLO improvements, TR-181 DM support, and reporting alignment). The work yielded improved client visibility, consistent association reporting to WebUI/NOC, and standardized MLO configuration through TR-181 DataModel. Commit-driven changes were validated via TR-181 data model checks (dmcli) and driver-level verification.

February 2026 monthly summary for rdk-wifi-hal. Focused on stability improvements for MLO/MLD VAP handling and preventing crashes when disabling a VAP in an MLD group. This work reduces outages in multi-AP deployments and improves client connectivity consistency across SSIDs. Highlights include a targeted fix with RDKB-63482 and associated changes to MLO-enabled VAP handling.

January 2026: Delivered scalable MLO/MLD improvements and stability fixes across OneWifi and rdk-wifi-hal, enabling higher capacity and more reliable operation in multi-MLD deployments while simplifying configuration and build management.

December 2025 monthly summary for rdkcentral/OneWifi focusing on targeted optimization of MLD address change detection. Implemented a function to check MLD address changes exclusively on MLD-enabled VAPs, preventing unnecessary checks on non-MLD VAPs, thereby reducing false positives and improving overall WiFi stability and performance during dynamic MLO configurations.

Month: 2025-11 Key features delivered: - Dynamic MLD Addressing for Runtime MLO Reconfiguration in OneWifi: Updated MLD address generation logic to regenerate MLD_Addr in response to runtime MLO configuration changes, enabling seamless MLO VAP reconfiguration with no downtime. Commit 465af1474fa5b17b7b2ca457f61ab2611983c7d3 (BCOMB-3166). - Wireless Connectivity Reporting Enhancement: MLO fields in Reduced Neighbor Report IE in rdk-wifi-hal: Added MLO-related fields to the RNR Information Element to expose MLD link information, improving roaming decisions and diagnostics. Commit 1c72e54405b61b41463566534a143994fd9e4cc7d (RDKB-61822). Major bugs fixed: - None reported this month. Work focused on feature delivery and hardening of runtime MLO configuration paths and reporting features. Overall impact and accomplishments: - Improved runtime configurability and reliability for MLO setups, reducing manual intervention and potential downtime during topology changes. - Enhanced visibility into MLO connectivity for client devices and access points, enabling faster diagnostics and better roaming performance across multi-link deployments. - Strengthened collaboration across repos (OneWifi and rdk-wifi-hal) to deliver end-to-end MLO support. Technologies/skills demonstrated: - TR-181 Data Model driven runtime reconfiguration, MLD address generation, MLD link concepts. - Reduced Neighbor Report IE enhancements and MLO parameter propagation. - Cross-repo integration, code collaboration, and issue tracking (BCOMB-3166, RDKB-61822).

October 2025 — RDK WiFi HAL (rdkcentral/rdk-wifi-hal): MLO VAP reliability improvements and build-time hardening. Implemented conditional reconfiguration for split_assoc_req and mbssid_num_frames to keep MLO VAPs up after VAP down-up changes and persisted split_assoc_req to nvram to minimize runtime interface down-ups. Fixed build issues for MLO VAP reconfiguration via conditional compilation, handling ports inactive and platforms lacking FEATURE_HOSTAP_MGMT_FRAME_CTRL. Result: higher MLO uptime, fewer runtime disruptions, broader cross-platform support, and clearer CI/build signals.

Summary for 2025-09: In rdk-wifi-hal, delivered critical work on Multi-Link Operation (MLO) stability and hostapd compatibility, driving higher network reliability and interoperability across deployments. Focused on robust initialization, configuration handling, and compatibility with older hostapd versions while enabling MLO features for modern devices. Business value includes reduced downtime during VAP reconfigurations, more predictable BSS behavior, and easier future enhancements.

End-to-end MLO enhancements across the rdk-wifi-hal and OneWifi teams were delivered in August 2025, emphasizing reliability, upgrade safety, and data-model driven configuration for multi-link WiFi. Key work includes integration with TR181 DataModel, stability fixes under dynamic reconfiguration, and a safe upgrade path for MLO configurations. This work reduces runtime crashes, enables centralized management, and supports smoother deployments for devices with multiple wireless links.

July 2025 (rdkcentral/OneWifi): Implemented MLO-aware MAC address handling for VAPs to ensure correct MLD address assignment across VAPs within the same MLO group. This involved updating wifi_db_apis.c to derive MLD addresses based on MLO group configurations, ensuring shared MAC for VAPs in the same MLO group while preserving individual MACs for non-MLO VAPs. The changes were tied to RDKB-60772 and delivered through the commit that implements proper mld_addr selection (#485). Overall, this work reduces MAC/address conflicts, improves client connectivity in multi-AP scenarios, and lays groundwork for more robust MLO support.
