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:
- Check your device for signs of power. If the LED or LCD screen is on, try to troubleshoot your UniFi Device Connectivity.
- 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.
- Try a different switch port or PoE adapter to rule out port damage.
- 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.
