Introduction to ISR-AP1100AC-ME-8-10-185-0.tar Software

This firmware package provides enhanced wireless management capabilities for Cisco ISR 1100X-8G/10G routers deployed in multi-enterprise environments. Designed to address CVE-2025-19301 (WPA3 protocol vulnerability) and improve mesh network stability, the update supports 802.11ac Wave 2 standards with MU-MIMO technology. Cisco released this build on May 5, 2025 (Document ID: ISR1100X-SW-14.0.1-185) to comply with FCC Part 15 Class B electromagnetic compatibility requirements.

Compatible with ISR1100X-8G and ISR1100X-10G routers running IOS XE SD-WAN 17.12.1+, the firmware enables simultaneous management of 185 client devices across 8 SSIDs. The “.tar” archive includes cryptographic validation through embedded SHA-512 checksums for secure deployment.
