​​Introduction to FWF_60E_DSL-v6-build1828-FORTINET.out Software​​

This firmware release (build 1828) provides critical updates for ​​FortiWifi 60E DSL​​ security appliances running FortiOS 6.4.5, specifically designed to enhance DSL modem stability and wireless network security. As part of Fortinet’s Q4 2024 security maintenance cycle, it addresses 9 CVEs identified in previous versions while optimizing threat detection throughput for small-to-medium business networks.

Compatible exclusively with ​​FortiWifi 60E DSL models​​ (FWF-60E-DSL), this build requires FortiOS 6.4.5 as its baseline operating system. The firmware follows Fortinet’s standardized versioning pattern observed in similar releases like FGT_500D-v6-build1828-FORTINET-6.4.5.out, with deployment timestamps indicating availability through authorized channels since November 2024.
