1. Introduction to FWF_60E_DSLJ-v6-build1914-FORTINET.out Software

This firmware release (build 1914) delivers critical security enhancements and connectivity optimizations for FortiWiFi 60E DSL series devices running FortiOS 6.4.15. Designed for branch office deployments requiring integrated DSL connectivity, it resolves 12 CVEs identified in previous versions while improving WAN link redundancy capabilities.

Compatible exclusively with FortiWiFi 60E DSLJ models (FWF-60E-DSLJ) manufactured after Q3 2023, this update supports DSL Annex A/B/C configurations for global telecom standards. Officially released on February 10, 2025, the build completed 1,200+ validation tests across 40 network profiles under Fortinet’s Security Fabric certification program.
