Release the button, and the device will reboot with factory defaults.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power / LED off | Power adapter not connected; PoE+ not active or faulty cable. | Check power adapter connection and outlet. Verify PoE+ switch/injector is active and Ethernet cable is functional. |
| Cannot connect to Wi-Fi network | Incorrect Wi-Fi password; AP not broadcasting SSID; AP not configured. | Verify Wi-Fi password. Check AP configuration via web interface or Nebula. Ensure AP is powered on and LED is solid green. |
| Slow Wi-Fi speeds | Interference; AP placement; outdated firmware; too many connected devices. | Relocate AP away from obstructions/interference sources. Update firmware. Reduce number of active devices or consider adding more APs. |
| Cannot access AP web interface | Incorrect IP address; network connectivity issue; AP in Nebula mode. | Verify AP's IP address. Ensure your computer is on the same subnet. If using Nebula, manage via the cloud platform. Try resetting the AP to factory defaults. |
| Nebula cloud connection issues | Internet connectivity issue; firewall blocking; incorrect Nebula registration. | Check internet connection. Ensure firewall allows outbound connections to Nebula servers. Verify AP is correctly registered in your Nebula account. |
