Troubleshooting Offline UniFi Devices

There are various "layers" of connectivity which may result in UniFi devices appearing as "Offline." Follow these steps to perform basic Layer 1 (physical) troubleshooting:

  1. Check your device for signs of power. If the LED or LCD screen is on, try to troubleshoot your UniFi Device Connectivity.
    Note: Switch LCD screens may remain dark for several minutes following an update.
  2. Replace the cables. Damaged cables are one of the most common causes for devices not receiving power. Try one of our high-quality UniFi cables.
  3. Try a different switch port or PoE adapter to rule out port damage.
  4. Get a replacement device. If your device is within its warranty period, you can submit a request for a new unit at our RMA Portal.
