If your router is connected to a UPS or inverter but your internet disconnects during a power cut, the issue isn’t with your router — it’s because the fiber network (OLT / junction box) outside your building also loses power.
Your Wi-Fi signal remains ON, but the optical fiber line temporarily goes offline until power is restored to the network source.
⚙️ Understanding the Issue
Mahek Broadband uses FTTH (Fiber to the Home) technology, where your internet connection depends on two power sources:
- Your Router and ONT – Inside your home
- The Fiber Node or OLT (Optical Line Terminal) – Located outside your home/building
During a power outage:
- Your router continues working (thanks to UPS/inverter).
- But the external OLT or fiber distribution point may not have power backup in all areas.
- This results in a temporary signal loss, even though your Wi-Fi appears ON.
💡 Think of it like your router being powered but the “internet highway” outside is temporarily closed.
🧭 How to Confirm It’s a Power Outage Issue
Check your ONT device (Fiber Box) during a power cut:
| Light | Status | Meaning |
|---|---|---|
| PON (Green) | ✅ Fiber signal active | |
| LOS (Red/Blinking) | ⚠️ Signal lost (network node offline) | |
| Power (ON) | ✅ Device receiving power from your UPS |
If LOS turns red or blinks during the power cut — it confirms the network node (OLT) has lost power, not your home setup.
⚡ Solutions & Recommendations
🔌 1. Ensure Both ONT & Router Are on Backup
- Make sure both devices — router and ONT — are connected to UPS or inverter.
- If only the router is powered and ONT turns off, the internet will disconnect even if Wi-Fi stays on.
🔋 2. Check Your Backup Duration
- Typical small UPS units (600–800 VA) provide around 30–45 minutes of power.
- If power cuts last longer, your ONT or UPS may shut down mid-outage.
- Consider upgrading to a longer backup or DC UPS specially designed for routers + ONTs.
🧰 3. Ask About OLT Power Backup in Your Area
- In some areas, Mahek Broadband has installed OLT backup systems to prevent signal drop during outages.
- Contact support to check if your building or network zone has this feature — or request one if frequent cuts occur.

💡 Pro Tips
- Use a Router + ONT DC UPS combo — small, efficient, and ideal for power-cut areas.
- Avoid frequent power cycling during short outages.
- For business users, consider high-capacity UPS or inverter connection to ensure uninterrupted service.
