How to Reset a Frontier Router and Fix a Red Light

Frontier equipment differs between fiber and DSL and across models, but the troubleshooting order is the same: check for an outage, check the connection to the network, restart and reset only if needed. This page explains how to restart and reset a Frontier router and how to approach a red light. Light meanings vary by model, so confirm details against your device's guide.

Restart a Frontier router

Unplug the router's power cord. If you have a separate modem or a fiber Optical Network Terminal (ONT), note its lights and leave it powered unless instructed otherwise.
Wait about a minute.
Plug the router back in and wait several minutes for its lights to settle.
Check the internet by loading a page on a device.

Factory reset a Frontier router

If a restart fails, press and hold the recessed reset button with a paperclip for the time your model specifies, then wait for it to reboot. This erases WiFi settings, so reconnect with the defaults on the label.

Frontier router red light

As a general rule, a red or blinking red light means the device cannot connect to the internet. Work through these steps:

Check for a Frontier outage using the Frontier app or outage page on mobile data.
If you have fiber, check the ONT lights for a fault and confirm it has power.
Reseat the cable between the wall or ONT and the router, and between any modem and router.
Restart the router, then the modem or ONT if the lights suggest a fault.
Try another outlet for power.
Reset the router as a last step.

Frontier WiFi slow or dropping

Place the router in an open, central spot away from microwaves and thick walls, keep it cool and use the 5 GHz network near the router for speed.

When to contact Frontier

If there is no outage and the light stays red after a restart, cable checks and an ONT check, contact Frontier and describe what you have tried. Ask about equipment replacement if the router keeps failing.

The bottom line

Check the outage status, then the cables, then restart. Reset only when needed, and call Frontier if a red light survives.
