Introduction to FWF_81F_2R_3G4G_POE-v6.M-build2000-FORTINET.out Software
This firmware package (build 2000) delivers critical updates for Fortinet’s FortiWifi 81F-2R-3G4G-POE series devices running FortiOS 6.4.15. Released under Fortinet’s Q2 2025 security advisory cycle, it addresses 9 CVEs rated “critical” while optimizing dual-radio WiFi 6 performance and 4G/LTE failover capabilities for distributed enterprise networks.
Designed specifically for the 81F-2R-3G4G-POE hardware variant with 24-port PoE+ switching capacity, this update introduces 30% faster threat inspection throughput through NP6 processor optimizations. Network administrators managing campus Wi-Fi deployments or remote industrial sites will benefit from its enhanced dynamic frequency selection (DFS) algorithms and improved cellular modem stability.
