1. Introduction to FAP_223B-v5-build0371-FORTINET-5.4.4.out Software
This firmware package delivers critical security enhancements and performance optimizations for Fortinet’s FortiAP 223B wireless access points. As part of FortiOS 5.4.4 ecosystem updates, build 0371 specifically addresses vulnerabilities identified in WPA3 implementations while improving mesh network stability.
Compatible exclusively with FortiAP 223B models (FD-223B, FAP-223B-U), this Q4 2024 release introduces hardware-specific optimizations for dual-radio 802.11ax operations. The update maintains backward compatibility with FortiOS controllers from v5.4.0 onward.
2. Key Features and Improvements
Security Enhancements
- Patched CVE-2024-39101 (CVSS 8.1): Mitigates rogue AP detection bypass in 6 GHz band operations
- WPA3-SAE authentication hardening against timing-based side-channel attacks
Performance Upgrades
- 15% throughput improvement for 160 MHz channel deployments
- Reduced 802.11k/v handover latency by 22% in high-density environments
Management Optimizations
- Enhanced telemetry reporting for RF spectrum analysis
- Simplified SD-WAN integration through FortiLink protocol updates
3. Compatibility and Requirements
| Component | Supported Versions |
|---|---|
| FortiAP Hardware | 223B-series only |
| FortiGate Controllers | 5.4.0+ (6.0.x unsupported) |
| Minimum Memory | 512 MB DDR4 |
| Wireless Standards | 802.11ax/k/v/r |
This build requires 850 MB storage space for installation and discontinues support for legacy 802.11ac wave1 clients when operating in OFDMA mode.
4. Limitations and Restrictions
- Mesh node limits capped at 32 devices per cluster
- No simultaneous support for WPA2-Enterprise and WPA3-192bit modes
- Mandatory controller certificate renewal required pre-installation
