Step 1 Ensure that the IPC works in stable voltage.
Step 2 Capture data packets sent by the IPC and analyze the captured data packets.
If the IPC continuously sends broadcast packets to 0.0.0.0, upgrade the IPC to the latest version.
There might be network storms when the IPC connects to the optical network unit (ONU) of some models. If this occurs, upgrade the IPC to the latest version.
If the IPC sends packets normally, go to Step 3.
Step 3 Reset the IPC and ping the IPC again after powering it on.
Step 4 Check whether the fault is rectified.
If yes, no further operation is required.
If no, contact your service provider for assistance.
