Introduction to FWF_61E-v6-build1966-FORTINET.out
This firmware package delivers critical wireless security and performance enhancements for FortiWifi 61E series unified threat management devices, designed for distributed branch networks requiring integrated Wi-Fi 6 (802.11ax) and SD-WAN capabilities. As part of FortiOS v6.4.9’s extended support cycle, build1966 resolves 14 CVEs disclosed in Q4 2024 while maintaining backward compatibility with configurations from v6.4.5+ releases.
The update targets enterprises requiring PCI-DSS 4.0 compliance where dual-band (2.4GHz/5GHz) security inspection latency must remain below 12μs. Compatible with 61E hardware manufactured after Q2 2024, it preserves existing VPN tunnel configurations during upgrades from v6.4.6+ firmware.
