As the world’s leading network connectivity tester, LinkRunner™ provides immediate visibility and value to network professionals responsible for delivering network services. By combining Ethernet test capabilities for copper and fiber links with the Android™ OS1, LinkRunner G2 represents a breakthrough in handheld network test that elevates the proficiency and productivity of network technicians responsible for troubleshooting as well as deployment and validation of network connected devices.

Importance of Automated Network Connectivity Testing

Paramount to the deployment of any type of network-connected device is validating link and network services from the point where end devices connect to the network. By automating those many tests in a simple but complete AutoTest, instead of requiring specialized expertise to understand the many underlying elements of network connectivity, even the least experienced technician can execute the test.

AutoTest performs a default set of key network connectivity tests in seconds, providing a standardized test process that enables technicians to quickly and accurately identify if the problem is in the connected device, the network, or lack of proper PoE being supplied to the RJ-45 jack.

Standard AutoTest includes:

  • TruePower™ PoE Class 0-4, UPOE
  • Link speed/duplex
  • Nearest switch including slot/port/VLAN/Voice VLAN
  • DHCP IP Address assignment


  • DNS Validation
  • Gateway Router Validation
  • Reachability to target resource i.e. internet

When customization of the AutoTest is needed, profiles can be defined to ensure a standardized test process is executed when variables about the link under test are needed. While these settings can be easily changed in use, profiles can be configured by a senior team member to ensure less-skilled technicians are executing an AutoTest that is specific to their network environment, which is particularly useful in organizations who manage distributed locations.

Examples include:

  • Site-specific PoE configuration
  • 1000BASE-T validation
  • 802.1x authentication
  • IPv4/IPv6
  • DHCP/Static IP


  • Proxy settings
  • VLAN ID and Priority
  • User-defined MAC
  • Up to 10 custom-defined ping or TCP port open targets

At the completion of each AutoTest, the result is automatically uploaded into the included Link-Live results management and reporting database and sent to any number of recipients via email. Users have the ability to add additional information that will append to the link test either directly from LinkRunner G2 or through email.

Examples of useful information to document with the AutoTest result:

  • Trouble ticket number
  • Jack location
  • Use the on-board camera along with an Android app to scan a QR/Barcode
  • Attach a photo of a serial number, asset tag or just proof of device install

Benefits of Android OS


Eliminate Security Risk of Using Personal Devices
Many technicians today use their personal mobile device on the job to access vendor apps, check trouble tickets, look up technical documents, calculate IP address ranges, configure network equipment, and more. However, the use of a personal device for job-related tasks could be considered a security risk. In addition, it may have only limited access to network infrastructure information (if connected to a guest VLAN, for example).

But the mobile device has no ability to validate wired Ethernet infrastructure – it cannot test PoE, cabling, link negotiation or network services. While it features Wi-Fi and Bluetooth connectivity, many networked end-point devices do not support these connection methods. So multiple tools are needed.

Workflow Efficiency Gains
Imagine how much time it would save to have a single device that could:

  • Receive a trouble ticket
  • View .pdf documents
  • Verify network services via AutoTest
  • Automatically document test results
  • Do all things Wi-Fi and Bluetooth that you can do with your personal mobile device with the optional Edimax2 Wi-Fi/Bluetooth USB Adapter
  • On-board camera to document installed devices, scan QR/barcodes, etc.
  • Configure any IoT device that supports an Android app or web connection via Chrome browser
  • Use Android apps to do things like:
    • Configure an IoT device (security camera, AP, lighting, HVAC)
    • Telnet into a switch
    • Run a speed test
    • Access an IP calculator
    • View info provided by a Bluetooth-supported sensor
    • Plug in a USB printer and along with the companion Android app, print labels
    • Get help – start a webex, invite others and share your screen enabling quick assistance without unnecessary downtime

The possibilities are endless as the world of smart devices goes. Apps are available for virtually anything you need to do. Visit https://link-live.com/public/apps to see the current list of readily available free apps. Don’t see something you need, just request it at the NETSCOUT® App Store and we will verify the app and get it posted. Note: only apps that are free to consumers are available for install on LinkRunner G2, chargeable apps are not supported.
