  First, verify that all connectors, including the telephone line, Ethernet cables, and power adapter, are securely connected. Next, check if you can log in to the web management page of the Network Router. Then, contact your ISP to confirm that the VPI/VCI, Connection Type, account username, and password are correct. If any settings are incorrect, correct them and try again. If problems persist, restore your Network Router to its factory default settings and reconfigure it.
