​​Introduction to FAP_221E-v600-build0465-FORTINET-6.4.6.out Software​​

​​FAP_221E-v600-build0465-FORTINET-6.4.6.out​​ is a critical firmware update for Fortinet’s FortiAP 221E wireless access points, addressing security vulnerabilities and enhancing Wi-Fi 6 (802.11ax) performance. Released under Fortinet’s Q3 2024 Security Advisory Program, this build resolves 17 documented CVEs while optimizing radio resource management for high-density environments.

Compatible exclusively with FortiAP 221E hardware revisions C and later, this firmware (version ​​6.4.6 build 0465​​) introduces adaptive RF spectrum analysis and improved WPA3-Enterprise authentication protocols. Enterprise administrators managing healthcare, education, or IoT deployments will benefit from its enhanced threat containment capabilities.
