If the LOS (Loss of Signal) light on your ONT (Optical Network Terminal) or router is red or blinking, it means your device is not receiving a stable fiber signal from Mahek Broadband’s network.
This is one of the most common indicators of a line disconnection, fiber cut, or signal fault — but don’t worry, it can be fixed quickly.
🚨 What the LOS Light Indicates
| LOS Light Status | Meaning | Action Needed |
|---|---|---|
| ❌ Red (Blinking or Stable) | No fiber signal / broken connection | Contact Mahek support immediately |
| ⚪ Off | Normal – Fiber signal detected | No action needed |
| 🟢 Green (Steady) | Fiber link stable (depends on model) | Connection working properly |
💡 LOS stands for “Loss of Signal.” When it’s red or blinking, your ONT cannot communicate with our network.
⚙️ Common Causes of LOS Red Light
- 🔌 Loose or Disconnected Fiber Cable
- The fiber connector may have come loose from the ONT or wall socket.
- 👉 Gently reinsert the connector and avoid touching the fiber tip.
- ✂️ Fiber Cut or Damage
- The cable might be bent, cut, or broken due to movement, furniture pressure, or cleaning.
- 👉 Do not try to repair the fiber cable yourself. Contact support for technician replacement.
- ⚡ Power or Network Outage
- Temporary fiber fault in your area or network maintenance underway.
- 👉 Wait a few minutes — if the LOS light remains red, contact support.
- 🔧 ONT or Router Fault
- Rarely, the ONT may malfunction or require reconfiguration.
- 👉 Restart your ONT and router — if LOS stays red, technician visit may be required.
