Introduction to FAP_221E-v700-build0367-FORTINET.out

This enterprise-grade firmware release (v700-build0367) delivers critical security enhancements and operational optimizations for Fortinet’s 221E series wireless access points. Designed for mid-market retail and hospitality deployments, the update resolves 7 CVEs identified in legacy versions while introducing Wi-Fi 6 performance tuning capabilities. Officially released on May 10, 2025, it aligns with FortiOS 7.8.2’s centralized management requirements for distributed networks.

Specifically engineered for high-client-density environments, this build introduces adaptive band steering algorithms and enhanced spectrum analysis. Compatible exclusively with FortiAP-221E hardware (models FAP-221E/FAP-221E-POE), it requires minimum FortiCloud Controller v6.6.2 or on-premises controllers running FortiOS 7.4.7+.
