Once installed, you can launch it from your Chrome Apps page ( chrome://apps Option B: Standalone Download (Desktop) Visit the official Ubiquiti Downloads page Select the category from the sidebar. Look for the Device Discovery Tool
The discovery feature relies on UDP/TCP port 10001. EdgeRouter devices with default WAN firewall policies (from the Basic Setup wizard) block all probes to this port, making them undiscoverable from the WAN.

For non-EdgeRouter devices or for network-wide policy, you can block these probes at your firewall by dropping all incoming connections to UDP/TCP port 10001 .
The query "ubnt discovery v2.4.1 free download install" reflects a real need for efficient device discovery on Ubiquiti networks. While the software is legitimately free, the risks of downloading from unofficial sources are severe. By obtaining the installer directly from Ubiquiti, verifying dependencies like Java and Npcap, and running the tool with administrator privileges, network technicians can safely manage legacy Ubiquiti hardware. However, for any new deployment, one should embrace Ubiquiti’s current management platforms, leaving v2.4.1 as a tool for specific historical contexts rather than everyday use. Always prioritize security over convenience when sourcing network administration utilities.
