FiOS Internet

 Using the WAN Coax light to troubleshoot the Verizon 9100EM router  
  1. The most common cause of a lost connection to your FiOS service is a bad connection between the router and your FiOS wall connection.
    • Check the connection where the coaxial cable attaches to the coaxial connection on the back of the Verizon router.
    • Check the connection where the same coaxial cable attaches to your FiOS wall connection.

  2. If the WAN coax light is now illuminated but you can't connect to the Internet, continue with Troubleshooting Step 3.
  3. If the WAN coax light remains off, contact the Verizon Fiber Solutions Center.
