Troubleshooting Sudden Resets

Back to Top

Unexpected device resets/factory default can often be caused by the following:

  • Short in the ethernet cable. To troubleshoot, inspect the cable, test it by changing with another one known to be working and remove if necessary.
    • Often related to water in the cable.  
    • Physically damaged cable 
  • End-user resetting via PoE Reset. To troubleshoot, disable the Reset button under airOS's System section as a test. 
    ATTENTION:All airMAX radios (excluding Nanostation5AC) have a remote reset circuit that allows you to factory default a radio remotely via the "Reset" button located on most Ubiquiti PoE injectors.  This works by applying a voltage to one of the data pairs.  While it is possible to disable the remote reset function on the System tab, this should only be used to verify the issue and not as a long-term fix.
  • Device connected to the airMAX radios ethernet port is faulty and applying a voltage to data pairs. This includes, but is not limited to: PoE injectors, PoE switches, or PoE voltage converting adapters. To troubleshoot, replace the connected device.
