3 Fixes for My Fios Gateway Blink Red Light

You can fix My Fios Gateway router blinking red or orange using these steps.

Fix 1: Restart Your Entire Fios System (Works 60% of the Time)

1. Unplug your Fios gateway (router)
2. Locate your ONT box (white/gray panel, usually in basement/garage)
3. Unplug the ONT’s power
4. Wait 30 seconds (critical!)
5. Plug ONT back in, wait for the lights to stabilize (about 2 minutes)
6. Plug the router back in
7. Wait 5 minutes for a full reboot

This fixes the temporary glitches and software hiccups.

Fix 2: Check Your Fiber Cable Connections

1. Find where the fiber cable connects (either at ONT or gateway)
2. Disconnect and reconnect the thin fiber wire (handle gently!)
3. Inspect for damage – look for:
   • Bent or kinked cables
   • Chewed wires (pets/rodents)
   • Corroded connectors
4. Try a different fiber port if your ONT has multiple

These steps will fix the lost connections, physical damage.

Fix 3: Test for Power Issues

1. Check if other ONT lights are on:
2. No lights at all? Power supply failed
3. Only battery light on? Electrical issue
4. Try a different power outlet
5. Test with different power cables if possible
6. Look for tripped circuit breakers

Note: If your ONT battery is beeping, it may need replacement (call Verizon support service number 800-922-0204)
