Introduction to ISR-AP1100AC-ME-8-10-190-0.tar Software

This firmware package (version 8.10.190) delivers critical enhancements for Cisco ISR 1100 Series Integrated Services Routers with embedded wireless access point functionality. Designed for branch office deployments, it combines SD-WAN capabilities with advanced security protocols to optimize hybrid network performance. The release addresses 14 CVEs identified in prior versions, including vulnerabilities in DHCPv6 packet processing and control-plane policing mechanisms.

Compatible with both ISR1100-4G/6G and ISR1100X-4G/6G models, this update supports simultaneous operation of 802.11ac Wave 2 access points while maintaining WAN throughput up to 1.8 Gbps under SD-WAN IPsec encryption loads. Cisco officially published this build on March 26, 2025, as part of its quarterly security maintenance cycle.
