PROFILE

Zhi-jun You

Worked on OpenWrt and DragonBluep/openwrt repositories to enhance wireless device reliability and configuration management. Delivered features such as NVMEM-based storage for EEPROM and MAC addresses, manual control for HE TWT responder, and improved gating for wireless protocol options. Addressed bugs affecting hostapd compatibility, Wi-Fi configuration stability, and device boot reliability by refining device tree structures and scripting logic. Used C, DTS, and Shell scripting to implement targeted fixes and features, ensuring safer configuration paths and reducing support overhead. Demonstrated a disciplined approach to firmware and Linux kernel development, with changes focused on maintainability, interoperability, and upstream alignment.

February 2026 monthly summary for DragonBluep/openwrt focusing on stabilizing W6 device boot and network initialization by provisioning precal data across the W6 family. Delivered kernel/DT changes to ensure precal data is present for W6 devices (W6 common DTS, Acer Predator W6, Acer Vero W6m), addressing bootlog errors and aligning with the NVMEM-based data provisioning migration. This work improves device boot reliability, reduces failure modes during startup, and supports consistent wifi initialization on W6 variants.

November 2025: Delivered a targeted Wi‑Fi reliability improvement for namiltd/openwrt by fixing ht_capab initialization for 20MHz mode in hostapd.conf. The change prevents empty ht_capab entries, stabilizing 20MHz configurations across devices and reducing post-deploy support issues. Implemented in wifi-scripts/u-code with a clear init path; patch prepared for upstream review and signed off by maintainers (commit 7ea377ed715078c9559891d69a455e0796be4eed).

October 2025 — Stability and interoperability improvement for OpenWrt wireless configuration. Implemented a targeted fix so airtime_mode is appended to hostapd.conf only when the value is greater than 0, addressing hostapd-mini compatibility issues and preventing invalid config lines. Delivered with a focused patch in namiltd/openwrt, reducing startup/config errors for devices using hostapd-mini and lowering support overhead. Demonstrated disciplined config templating and version-controlled changes with minimal risk.
