Introduction to ISR-AP1100AC-ME-8-10-151-0.zip Software

This firmware package enables Cisco ISR 1100 series routers to operate as secure wireless access points while maintaining SD-WAN functionality. Designed for hybrid work environments, it integrates Viptela operating system capabilities with enterprise-grade Wi-Fi 5 (802.11ac Wave 2) management, supporting dual-radio operations at 2.4GHz and 5GHz frequencies.

Compatible with ISR1100X-4G/6G models, this release (Version 8.10.151) became available through Cisco’s validated software channel in Q4 2024. It addresses critical vulnerabilities identified in CVE-2024-20351 while enhancing interoperability with Catalyst 9800 wireless controllers.
