The Ubiquiti Device Discovery Tool v2.4.1 is a specialized network utility designed to locate and identify Ubiquiti hardware on a local network. While it was once a staple for network administrators, the tool is now considered legacy or deprecated. The Evolution of Device Discovery
Originally released as a Java-based application and a Chrome browser extension, the v2.4.1 tool served a singular, critical purpose: scanning local subnets to find IP and MAC addresses of devices like airMAX radios and UniFi access points.
Functionality: It uses a local network probe (UDP/TCP port 10001) that all compatible Ubiquiti devices respond to.
The Shift: As Google phased out Chrome Apps, the legacy tool became increasingly difficult to run on modern systems.
Current Status: While the Java version (v2.4.1) can still be found in various archives or on GitHub for Linux users, it often requires older versions of Java (like Java 8) to function correctly. Installation and Setup
For those needing the specific v2.4.1 version for legacy hardware: Discovery Tool - Ubiquiti Community
Since Ubiquiti has shifted much of its management to the UniFi Network Server and UISP (for airMAX), the standalone UBNT Discovery Utility remains a critical legacy and troubleshooting tool. This guide covers what it is, where to get it legitimately, and how to install it.
For those new to the ecosystem, Ubiquiti Discovery Tool is a utility used to locate Ubiquiti devices on your local area network (LAN). It is essential when:
Navigate to the official Ubiquiti Community forums → Tools section. Verified links to v2.4.1 are often pinned by moderators.
If you are using modern Ubiquiti hardware (U6 Access Points, Wave devices, or UDM-Pro), UBNT Discovery v2.41 may not detect them. Consider these modern alternatives:

Installing Ubiquiti Discovery Tool on new Windows 10 Pro laptop
Q: Is "ubnt discoveryv2 41" the same as "UBNT Discovery Utility 2.4.1"? A: Yes. The search term drops the dots but refers to version 2.4.1.
Q: Can I install it on Windows 11? A: Yes, fully compatible. Run as administrator if you encounter any permission errors.
Q: Does it work with UniFi switches? A: For older UniFi switches (US-8-60W, US-24), yes, but newer Pro or Enterprise models are better discovered via the UniFi controller.
Q: Is there a portable version?
A: No official portable version exists. However, you can copy the installed folder (C:\Program Files (x86)\UBNT\...) to a USB drive and run the .exe manually on another Windows PC.
Q: Why does my antivirus flag it?
A: Some antivirus programs flag it for its broadcast packet behavior, which resembles network scanning malware. This is a false positive. Add an exception for the .exe.
The Ubiquiti Discovery Tool (Version 2.41) is a legacy utility software used to locate Ubiquiti Networks (UBNT) devices on your local network. This tool is essential for network administrators installing Ubiquiti equipment for the first time, as it helps find devices that do not appear in the standard user interface or are set to a different IP subnet.
⚠️ Important Note: Version 2.41 is considered legacy software. Ubiquiti has since moved toward "Ubiquiti Discover" (web-based) and the WPA mode in modern firmwares. However, v2.41 remains popular for managing older devices like the NanoStation, Rocket M, and airMAX M series.
Ubiquiti no longer prominently displays legacy discovery tools on its main website, but they are preserved in the community archives.
