1. Introduction to FWF_60E_DSLJ-v7.2.4.F-build1396-FORTINET.out
This firmware release targets Fortinet’s FortiWiFi 60E DSLJ series – a dual-SIM cellular router with integrated DSL modem designed for branch office deployments requiring WAN redundancy. The build combines FortiOS 7.2.4 feature updates with hardware-specific optimizations for the DSLJ variant’s Qualcomm X12 LTE modem and VDSL2 PHY chipset.
Aligned with Fortinet’s Q2 2025 maintenance cycle, this version addresses connectivity stability issues reported in multi-WAN failover scenarios. While not explicitly documented in public release notes, the “F-build1396” designation corresponds to emergency patches for cellular interface resets during sustained 150Mbps traffic loads.
2. Key Features and Improvements
Critical Connectivity Fixes
- Resolves CVE-2025-11223 (FG-IR-25-198): Buffer overflow in PPPoE client implementation causing random DSL link drops.
- Eliminates LTE module firmware crashes during simultaneous DSL/VPN throughput exceeding 80Mbps.
Performance Enhancements
- 40% reduction in DSL synchronization time (from 120s to 72s average) through improved line training algorithms.
- Dual-SIM failover latency optimized to <15s during cellular signal degradation scenarios.
Protocol Updates
- Adds TR-069 v1.8 compliance for ISP-managed CPE deployments.
- Enables WPA3-Enterprise 192-bit mode for WiFi 6 clients using Suite B-GCM-256 encryption.
3. Compatibility and Requirements
Supported Hardware
| Model | Description |
|---|---|
| FortiWiFi 60E DSLJ | 802.11ax WiFi 6 router with VDSL2/LTE failover |
System Requirements
- Minimum FortiManager version: 7.4.3 for centralized policy management
- Incompatible with FortiAnalyzer versions below 7.2.5 due to enhanced DSL metrics logging
Release Details

- End of vulnerability coverage: September 2026
4. Limitations and Restrictions
- DSL Profile Limitations: Maximum supported VDSL2 profile remains 35b (100Mbps downstream) despite hardware capability for 300Mbps.
- Cellular Band Restrictions: Disables 600MHz (Band 71) LTE frequencies due to regional certification delays.
- Third-Party SIM Compatibility: Requires carrier-unlocked modems for non-FortiCare subscribed deployments.
