This release introduces several important improvements focused on real-world Wi-Fi reliability and smarter network management. It brings meaningful refinements that reduce network congestion, and streamline configuration workflows for UniFi deployments.
Channel AI Optimization
Uses neighboring AP signals to optimize channel distribution. Designed for controlled, very high-density deployments where external interference is limited.
Provides a visual channel map for quick insights.
Automated optimization ensures balanced channel usage.
Quick-Scan Environment Analyzer
Adds an instant RF scan feature that identifies nearby networks, interference sources, and active channels in seconds.
Quick-Scan enables faster site evaluation, easier troubleshooting, and more informed deployment decisions — without taking radios offline or interrupting client traffic.
Instant Changes - Configuration Engine
Implements a high-speed configuration pipeline that applies changes directly to active subsystems without rebooting the entire device.
This greatly reduces downtime when adjusting SSIDs, VLANs, or radio settings, allowing administrators to make frequent updates in live networks without disrupting connected clients.
In larger installations, Instant-Changes can shorten network-wide updates from minutes to seconds.
Improvements
- Added packet capture support.
- Added Roaming Assistant support.
- Improved the 5GHz auto-channel selection algorithm ensuring a less noisy channel selection.
- Improved wireless adoption of mesh/auto-link devices in dense environments.
- Improved adoption stability.
- Improved interoperability across platforms.
- Improved DHCP traffic monitoring.
- Improved dual RADIUS server failover connectivity.
- Improved client connectivity.
