9100EM Router Issues

You can use the Power, Internet, and Ethernet lights on the front panel of the Verizon router to help diagnose home networking connectivity problems. Follow the steps below to diagnose and test the possible solutions for any connectivity problems you are experiencing.

Note: You might want to print these directions to make the troubleshooting process easier.

  1. Is the Power light illuminated?
    • Light is green: The Verizon router power is on. Go to Step 2.
    • Light is not solid green: The router isn't getting power.
  2. Is the WAN Coax light illuminated?
    • Light is green: The connection between the router and Verizon Online is established. Go to Step 3.
    • Light is off: Your router is unable to connect to the Verizon FiOS service.
  3. Is the Internet light illuminated?
    • Light is green: The transmission of data is confirmed. Go to Step 4.
    • Light is off: Data transmission is not confirmed.
  4. If the Verizon router is connected to your computer using an Ethernet cable, are any Ethernet lights illuminated (E1, E2, E3, or E4)?
    • Light for the port where a cable is connected is green: The Ethernet connection between the router and the computer or network device is established. Go to Step 5.
    • Light for the port where a cable is connected is off: No link is established between the Verizon router and your computer or network device.
  5. Reboot your computer by turning it off, waiting for 45 seconds, and then turning it back on. Re-check your router lights.

  6. Disconnect all networked computers and restart the computer connected to the router. Reconnect the other computers one-by-one to isolate the problem.

  7. If you still can't connect to the Internet, please contact Verizon Fiber Solutions Center.
