Ethernet Connection is Not Functioning

Symptoms

On the Network page, Ethernet has been configured but the system is not connected to Tesla (indicated with a red exclamation point icon).

Steps to Troubleshoot

If you have an Ethernet tester, test the connection on a successfully connected device.

  1. If the connection is not functioning:
    1. Select Check Internet Connection. If there is a checkmark next to Local Network Connected but not Tesla Services and Internet Connected, the issue is with the firewall and Powerwall 3 is unable to connect to Tesla's servers. Contact the customer's internet provider or create another network SSID without restriction that Tesla's servers can connect to.
    2. Ensure your router is set up for dynamic assignment of IP addresses (DHCP).
    3. If the Ethernet connection has been set up manually, ensure the Router IP and Subnet Mask are correct.
    4. Check the functionality of the DHCP connection by looking for the Powerwall 3 in the network list of the customer router. If the connection was successful, the Powerwall 3 serial number will be displayed in the list.
    5. If your device is directly connected to the Powerwall 3 via Ethernet cable, you can test the functionality of the Ethernet connection by performing a ping test. Set the laptop / device IP to 192.168.90.10 via the Network Adapter Settings.
    6. If the Powerwall 3 has successfully connected to the customer router, complex firewalls could have blocked the ports. Ensure that Port 443 is useable by the Powerwall 3 for in/out communication.
    7. Confirm the internet connection is functioning and the connection speed is fast enough by streaming a video or using a speed test webpage.
  2. If the connection is functioning:
    1. Confirm the Ethernet cable is plugged in at both ends.
    2. Confirm Ethernet runs are no longer than 150 ft (45 m).
    3. If the run is longer than 150 ft (45 m), install an Ethernet Power Line Adapter.
    4. Confirm the Ethernet cable is viable using a data cable tester.
    5. Verify that Ethernet has a checkmark and an IP address is displayed.
    6. Confirm the router / modem has power.
    7. Confirm the Ethernet cable is plugged into a LAN port.
    8. Power cycle the modem and routers.
