Learn how to use the simplified web interface of the Access Point to troubleshoot connectivity issues with Nebula.

Instructions:

  1. Accessing the AP:
    • Connect to the AP using the management IP address from the DHCP server or the default IP address (192.168.1.2).
    • Log in using the device password from Nebula or the default AP password.
  2. Dashboard Overview:
    • Upon login, you'll see the device's cloud control panel.
    • The AP automatically checks each connection stage when going online with Nebula and displays the results in the web-based graphical user interface (GUI).

    • If a stage fails (indicated by an orange circle), the AP will not proceed to the next stage. Hover over the circle for detailed error information.
  4. Detailed Stage Explanation:
    a. Check "Internet" Connection:
    • Ensure the AP's uplink ethernet is correctly configured to connect to the internet.
