How to Reset a Verizon Fios Router and Fix Fios WiFi Problems

Verizon FiosStep-by-step guideIndependent

Verizon Fios uses fiber, so the equipment includes an Optical Network Terminal (ONT) as well as a router, and both matter when you troubleshoot. This page explains how to restart and reset a Fios router and how to fix WiFi that is not working or a red light. Router models and lights vary, so check your model's guide if details differ.

Restart a Fios router

  1. Unplug the router's power cord.

  2. Wait about a minute.

  3. Plug it back in and wait several minutes for the lights to settle.

  4. Test the connection on a device.

You can also restart from the My Fios app, which helps when WiFi is down and you are on mobile data. Do not unplug the ONT unless support tells you to.

Factory reset a Fios router

If a restart fails, use the recessed reset button with a paperclip for the time your model specifies. This erases your WiFi name, password and custom settings; reconnect with the defaults on the label.

Fios router red light or no internet

  1. Check for an outage in the My Fios app or on Verizon's status page.

  2. Look at the ONT: make sure it has power and is not showing a fault.

  3. Check the cable between the ONT and the router; reseat it at both ends.

  4. Restart the router.

  5. Try another outlet for the router.

  6. Reset the router as a last step.

Fios WiFi not working: quick checklist

Check whether every device is affected. If only one device is, forget the network and reconnect. If all are, check for an outage, restart the router and test a device by Ethernet to separate a WiFi problem from an internet problem. Move the router to an open, central location if WiFi is slow or drops.

When to contact Verizon

If there is no outage and the light stays red or the internet stays down after a restart, an ONT check and cable checks, contact Verizon with your model and steps tried. Ask about equipment replacement if the router keeps failing.

The bottom line

Check the outage and ONT first, then restart the router. Factory reset only as a last step.

How do I reset my Fios router?

Restart first by unplugging it for about a minute, then plugging it back in and waiting several minutes. You can also use the My Fios app. A factory reset with the reset button erases your settings.

What does a red light on a Fios router mean?

A red light generally means the router has a problem or no connection. Check for an outage, the ONT and the cable between them, then restart.

Why is my Fios WiFi not working?

Common causes are an outage, a router that needs a restart, a loose cable or a problem on one device.

What is the ONT?

The Optical Network Terminal converts the fiber signal for your router. It has its own lights and should have power.

Will resetting delete my WiFi password?

A factory reset does. A restart does not.
