Sep 1, 2025September 2025 (2025-09) — Freifunk Berlin: bb configs module. Delivered four high-impact network configuration enhancements focusing on security, stability, and reachability. Implemented a private wireless network for S35 with a dedicated private DHCP network, filtering/isolation, and a WPA3-Personal (SAE mixed) wireless profile. Migrated knallt-m42 hardware from Zyxel to a Cudy AP3000 Outdoor, introducing new VLAN configurations and WireGuard tunneling. Introduced Link Quality Metric (LQM) configurations to zwingli and baumex to reduce OLSR route flapping, including Baumex router model alignment. Updated c-base-sky host entry to improve network reachability and cleaned up artifacts. These changes reduce configuration drift, improve security and reliability, and enhance overall network performance across locations.
