​​Introduction to FWF_80F_2R-v6-build5042-FORTINET.out Software​​

This firmware release (build 5042) targets FortiWiFi 80F 2R series appliances, designed for enterprise networks requiring dual-radio wireless connectivity alongside advanced threat protection. As part of FortiOS v6.4.15 branch updates, it addresses 14 CVEs identified in Fortinet’s Q1 2025 security advisories while optimizing Wi-Fi 6 performance and SD-WAN operations. The update specifically enhances radio frequency management for environments with high-density client deployments.

Compatible exclusively with FortiWiFi 80F 2R hardware (FG-80F-2R), this build aligns with Fortinet’s lifecycle support policy, providing security updates until Q4 2027. The “v6” designation confirms compatibility with FortiOS 6.4.x, resolving wireless client steering issues reported in earlier 6.4.12 deployments.
