Your router and ONT (fiber box) have multiple lights that show the current status of power, internet, and connection activity.
If these lights are blinking continuously, it doesn’t always mean a problem — some blinking is normal.
However, constant or unusual blinking (especially red or orange lights) can indicate a signal, connection, or configuration issue.
Here’s how to understand and fix it. 👇
🧩 1️⃣ Understand What the Lights Mean
| Light Name | Normal Behavior | Problem Indication |
|---|---|---|
| Power | Solid Green | 🔴 Off or blinking → Faulty adapter or power issue |
| PON / Internet | Solid Green | 🔴 Off or blinking → Network not connected |
| LOS | Off (Normal) | 🔴 Blinking → Fiber signal loss or disconnection |
| LAN / Wi-Fi | Blinking | Indicates active data transfer (Normal) |
| WPS | Blinking for 1–2 mins | Normal during WPS setup only; constant blinking = stuck process |
🧩 2️⃣ Normal vs Abnormal Blinking
✅ Normal Blinking:
- Wi-Fi or LAN lights blink when devices are connected and transferring data.
- PON light blinks briefly during startup or reconnection.
⚠️ Abnormal Blinking:
- LOS blinking red continuously → Fiber line issue.
- Power light flickering → Adapter fault or voltage fluctuation.
- All lights blinking at once repeatedly → Router reboot loop or firmware crash.
⚙️ 3️⃣ Step-by-Step Troubleshooting
🔹 Step 1: Restart Your Devices
- Turn off both your router and ONT (fiber box).
- Wait for 30 seconds.
- Power on the ONT first, wait until PON light becomes solid green.
- Then power on your router.
This resets the connection between your devices and our network.
🔹 Step 2: Check Fiber Cable Connection
- Ensure the fiber cable is securely inserted into the ONT port.
- Do not bend, twist, or pull the cable — it’s extremely sensitive.
- If the LOS light is blinking red, there’s likely a line cut or loose connector.
📞 Contact support for inspection if LOS doesn’t stop blinking.
🔹 Step 3: Check Power Adapter & Socket
- Make sure the power plug is firmly connected.
- Avoid using extension boards — plug directly into the wall socket.
- If the Power light flickers, the adapter may need replacement.
🔹 Step 4: Check Router Configuration
If the Internet/PON light keeps blinking green/orange:
- It means your router is on but not authenticated with our server.
- Re-enter your Mahek Broadband PPPoE username and password in the router’s settings page (
192.168.0.1or192.168.1.1). - Save and reboot.

🔹 Step 5: Observe After Reboot
After following the steps above:
- Power: Solid
- PON: Solid green
- LOS: Off
- Wi-Fi/LAN: Blinking normally
If all these look correct and you still have no internet, it may be a backend issue — contact support for quick resolution.
🧰 Still Blinking Continuously?
If your router or ONT continues blinking abnormally (especially Power or LOS lights):
- It may indicate faulty equipment, loose fiber, or firmware corruption.

💡 Quick Tips
✅ Ignore Wi-Fi blinking — it just means data is flowing.
✅ If LOS blinks red, avoid touching the fiber — it needs expert handling.
✅ Keep both ONT and router powered continuously for stable service.
✅ Restart devices weekly to refresh connection.
✅ If lights blink randomly after power cut, wait 1–2 minutes for automatic re-sync.
