Email alert message
Upon registration, Bumblebee devices send periodic heart beat messages to the Bumblebee portal. If the portal does not receive the heart beat message for a configured period, it declares the device's WAN connectivity is down and triggers a email alert or Webhook callback function.
Before the email alert is sent, the portal runs a reachability test to the ISP default gateway and based on the reachability test result, one can take actions accordingly.
Here are scenarios and suggestions.
The last mile connectivity is down
If the diagnosis indicates ISP default gateway is reachable, it implies the connectivity issue is in the last mile between CPE and the default gateway. Do the following:
Check the CPE power is plugged in
Check the CPE WAN cable is plugged in
If you have onsite support personnel, connect a laptop to the CPE device diagnostic port (Eth3) and type in a browser http://cpe.bumblebee:8080 You should see the diagnostic page.
Run ping test
Run trace route test
The middle mile connectivity is down
If ISP default gateway is not reachable, it implies the connectivity issue is at least in the middle mile between the ISP default gateway and the Bumblebee portal. Do the following:
Raise a support ticket with the service provider.
Post mortem analysis
During the connectivity down time, the CPE device does trace route to identify where the connectivity breaks down. When connectivity is restored, the trace route information is uploaded to the portal for post mortem analysis.
