January 2026 (2026-01) monthly summary for DragonBluep/openwrt. Focused on expanding wireless hardware support and refining the OpenWrt IPQ/ath79 wireless stack. Key deliverable: added TP-Link TL-WA1201 v2 support to the IPQ firmware package, including an ipq-wifi entry and a calibration variant to improve wireless performance and compatibility. This work enhances device coverage, reduces customer support overhead, and positions the project for broader hardware adoption. While there were no explicit major bugs closed this month, the work yielded tangible performance and compatibility improvements across the WiFi stack. Technologies demonstrated include IPQ firmware integration, ath79 calibration variants, and OpenWrt packaging best practices.

Monthly summary for 2025-11: Delivered targeted platform expansion and stability improvements for the DragonBluep/openwrt repo. Netgear Orbi device family support and enhancements were extended to cover RBS20 and RBK40/RBx40 lines, including router/satellite separation, WAN port designation, and LED/backlight indicators, with packaging integration to streamline firmware builds. Linksys MX4200v1 MAC extraction enhancements were implemented by adopting the ascii-env driver at the ipq807x tier, improving MAC configuration reliability. A UBI partition unit-address correction was applied to Netgear LBR20 in the device tree to align with the correct starting offset, reducing configuration errors. These changes collectively broaden device compatibility, improve configuration accuracy, and reduce field support needs.
