Ubiquiti released UniFi Network 10.2 for its UniFi Hosting and Cloud Key platforms, introducing a Topology Time Machine feature that allows administrators to review historical network maps. This update marks a significant shift in how the UniFi ecosystem manages historical data, providing a visual timeline of device connections, port status, and link changes over a rolling period.
The headline feature, Topology Time Machine, addresses a long-standing request for better diagnostic visibility. Users can scrub through a timeline to see exactly when a device disconnected or a specific link downgraded its speed. This tool is paired with a new Critical Events view, which surfaces high-priority alerts such as power failures, gateway disconnections, or loops detected by Spanning Tree Protocol (STP) to the top of the management dashboard.
Security enhancements in UniFi Network 10.2 include the implementation of Opportunistic Wireless Encryption (OWE). Also known as Wi-Fi Certified Enhanced Open, OWE provides individualized data encryption on open Wi-Fi networks without requiring a shared passphrase. This is particularly relevant for guest networks where WPA3-Personal or WPA3-Enterprise might be too restrictive for transient devices. The update also adds support for WPA3-Enterprise 192-bit mode, which utilizes the 256-bit Advanced Encryption Standard (AES-256) and the Galois/Counter Mode Protocol (GCMP-256).
Enhanced VLAN and client management
The update streamlines Virtual Local Area Network (VLAN) administration by consolidating VLAN-only networks and standard virtual networks into a single creation workflow. Ubiquiti also introduced a native DHCP Guarding feature that prevents unauthorized DHCP servers from assigning IP addresses on the network, which is critical for preventing rogue router interference in large-scale deployments.
The client list has been reworked to improve performance on controllers managing thousands of endpoints. New filtering options allow administrators to sort by Wi-Fi band, signal strength (RSSI), and connection duration simultaneously. For hardware like the Dream Machine Pro and the newer Dream Machine Special Edition, the software improves the reporting of SFP+ module temperatures and link synchronization status.
This release follows the recent rollout of the UniFi 8.6 firmware branch, signaling a rapid acceleration in Ubiquiti's software development cycle. UniFi Network 10.2 is currently available for UniFi Cloud Gateways and self-hosted Linux installations, with a rollout for the Windows and macOS versions expected to follow shortly.
