If your router keeps restarting on its own, or you notice the Wi-Fi disconnects and reconnects frequently, it usually means there’s an issue with the power supply, overheating, or internal hardware.
This problem can be frustrating, especially during online meetings or streaming, but it’s easy to diagnose with a few quick checks.
🧩 Step-by-Step Troubleshooting Guide
🔹 1. Check Power Adapter & Plug Connection
- Make sure your router’s power adapter is properly connected and not loose.
- Avoid using extension boards or multi-plugs — connect directly to a wall socket.
- If the adapter wire feels loose, warm, or flickers, it may need replacement.
- Use only the original power adapter supplied with your router.
⚡ Tip: Faulty adapters are the #1 cause of random router restarts.
🔹 2. Check for Power Fluctuations or Outages
Frequent voltage drops can cause your router or ONT to reboot repeatedly.
- Plug both into a UPS or inverter backup if your area faces power instability.
- Make sure your ONT (fiber box) is also getting constant power, since router restarts often follow ONT reboots.
🔹 3. Ensure Proper Ventilation (Avoid Overheating)
Routers generate heat during long use. Overheating can cause auto shutdown or restart to protect the circuit.
To prevent this:
- Keep your router in an open, airy space, not on carpets or closed shelves.
- Avoid placing it near direct sunlight, TVs, or modems generating heat.
- Clean the ventilation holes periodically with dry air to remove dust.
🔥 If the router feels unusually hot, switch it off for 10–15 minutes.
🔹 4. Check for Overload (Too Many Devices Connected)
Each router has a connection limit (usually 10–25 devices).
If too many devices connect simultaneously:
- The router memory overloads and triggers an auto-reboot.
- Disconnect unused devices and monitor if the issue stops.
For 50 Mbps+ or multi-user plans, use a dual-band router for better handling.
🔹 5. Update Router Firmware
Outdated firmware can cause system instability.
To update:
- Log in to your router’s admin panel (
192.168.0.1or192.168.1.1). - Go to Administration → Firmware Upgrade.
- Check for the latest update from your router manufacturer’s website.
- Apply the update and restart your router manually.
🧠 Firmware updates improve stability and fix automatic reboot bugs.
🔹 6. Disconnect Faulty LAN or USB Devices
If you’ve connected external devices like a hard drive or printer to the router’s USB port, try unplugging them.
Sometimes faulty peripherals draw excess power, forcing the router to shut down.
🔹 7. Perform a Factory Reset (Last Option)
If reboots continue:
- Press and hold the RESET button for 10 seconds using a pin.
- Reconfigure your Wi-Fi name and password.
- Check if the issue persists after a clean setup.
⚠️ Note: This will erase old settings, so note down your login details before resetting.
🧰 Still Rebooting Automatically?
If your router reboots even after checking all steps:
- It could be a hardware fault in the router or unstable ONT signal.
- Our technician can test your connection and replace faulty equipment if required.
