In April 2026, Hu contributed to the DragonBluep/openwrt repository by adding support for the I-O DATA WN-AX2033GR2 router, expanding device compatibility within the ramips target. Working primarily in C, Hu focused on Linux kernel and embedded firmware development, detailing device specifications and ensuring proper integration for the MT7621A-based platform with NAND flash (MX30LF1G18AC). The implementation included a clear upgrade process using initramfs-kernel.bin and sysupgrade.bin, aligning with existing device family standards. Hu’s work was delivered as a focused patch, documented for traceability in PR 22762, and demonstrated a thorough approach to hardware enablement and maintainability.
