Using the WAN light to troubleshoot the Verizon MI424WR router
- 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 Ethernet cable connects to the WAN port on the back of the Verizon router.
- Check connection where the same Ethernet cable connects to your FiOS wall connection.
- If the Ethernet WAN light is now illuminated but you can't connect to the Internet, continue with Troubleshooting Step 3.
- If the Ethernet WAN light remains off, contact the Verizon Fiber Solutions Center.
