Fix Fiber Jack Connection Issues

Learn how to identify status light signals, troubleshoot internet connectivity issues, and properly power cycle your gFiber Fiber Jack.

To fix gFiber connection issues, check the lights on your Fiber Jack. If you see a red light or no light, disconnect its power source (unplug the AC adapter or the Ethernet cable), wait 30 seconds, and plug it back in. Allow 2 to 3 minutes for the Fiber Jack to restart and show a solid blue or green status light.

Locate your Fiber Jack

The Fiber Jack is a wall-mounted device that connects your home to the gFiber network, translating optical light signals into internet data for your Wi-Fi router. To find your device:

Location: Look low on an interior wall, typically where utility lines enter your home.
Cabling: Check for an Ethernet cable connecting the Fiber Jack directly to your main gFiber router.
Power source: Identify whether it uses an AC power adapter plugged into a wall outlet or receives power directly through the Ethernet cable.

Identify your Fiber Jack model

Your Fiber Jack model determines how network status and power issues are displayed:

Single-light models: Feature 1 LED light on the front panel that changes color and blink patterns.

Four-light models: Feature 4 separate LED indicators labeled Power, Optical, Network, and Alarm.

Troubleshoot status light indicators

If your Fiber Jack goes offline, check the gFiber App for real-time network alerts.

Troubleshoot single-light status indicators

Use this guide to identify status codes on single-light Fiber Jack models:

Light LED	Meaning	What to Do
🔵 Solid blue	Normal operation	Your Fiber Jack is online. If internet access is down, inspect your gFiber Wi-Fi router or mesh points.
🔵 Blinking blue	Booting or updating	The device is starting up or downloading a software update. Wait 5 minutes for the light to turn solid blue.
🔴 Solid or blinking red	Line or hardware fault	Disconnect power from the Fiber Jack for 30 seconds, then reconnect it. If the light remains red, contact gFiber Support.
⚪ Off (No light)	No power	Verify that the cable is firmly connected to the Fiber Jack and power outlet. Test the wall outlet with another electronics device.

Troubleshoot four-light status indicators

Use this guide to diagnose status and connectivity issues on four-light Fiber Jack models:

Indicator name	Normal state	Problem state	Action required
Power	🟢 Solid green	⚪ Off	Verify that the AC power adapter is securely connected to the wall outlet and the Fiber Jack.
Alarm	⚪ Off	🔴 Solid red	The unit is not receiving an optical light signal. Check the fiber line for bends or physical damage, or check the gFiber App for service outages.
Optical	🟢 Solid green	🟢 Blinking green or ⚪ Off	Blinking indicates initial boot sequence; Off indicates no light signal. Wait 5 minutes. If status does not update to solid green, restart the device.
Network	🟢 Solid or pulsing green	⚪ Off	The Fiber Jack is online, but communication with your Wi-Fi router has stopped. Inspect the Ethernet cable connecting the Fiber Jack to your router.

Reset Your Fiber Jack

If your Fiber Jack displays a red light or no light, performing a hard reset clears system cache and re-establishes your network connection.

Disconnect the power source:
- Single-light models: In the room where your device is mounted, disconnect the Ethernet cable directly from the Fiber Jack or from the WAN port on the back of your main gFiber router.
- Four-light models: Unplug the AC power adapter from the wall outlet or pull the power pin directly from the bottom power port on the Fiber Jack.
Leave the device completely disconnected for 30 seconds.
Plug the power adapter or Ethernet cable securely back into your device.
Wait 2 to 3 minutes for the hardware to finish its boot sequence and register on the gFiber network.
Observe the front panel lights.
- Single-light models: Confirm the indicator turns solid blue.
- Four-light models: Confirm Power, Optical, and Network lights display solid green, and Alarm remains off.

When to Contact Support: If the Fiber Jack displays a red light or no light after completing the reset sequence, your fiber line may require external technical assistance. Contact gFiber support immediately. Inform the agent that you have a "red light on the Fiber Jack." This allows us to fast-track your service ticket and schedule a technician to inspect your external fiber line.
