Introduction to FWF_90D-v6-build0419-FORTINET-6.0.12.out Software
This firmware release (build 0419) delivers FortiOS 6.0.12 for FortiWiFi 90D wireless firewall appliances, providing extended security maintenance under Fortinet’s Long-Term Support (LTS) program. Designed for enterprises maintaining legacy network infrastructure, it bridges compatibility gaps between older hardware and modern cybersecurity protocols. The update focuses on critical vulnerability remediation and wireless performance optimization while preserving operational continuity for 802.11ac deployments.
Compatible exclusively with FortiWiFi 90D hardware (model FWF-90D), this firmware supports dual-radio 5GHz wireless access and integrates with FortiManager centralized management platforms. Originally released in Q2 2022 as part of FortiOS 6.0 feature branch, build 0419 represents the final cumulative security update before the platform’s scheduled end-of-support in June 2026.
Key Features and Improvements
1. Security Infrastructure Reinforcement
