Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your Deco M3 system.

Troubleshooting

If you encounter issues with your Deco M3 system, try the following troubleshooting steps:

No Internet Connection

• Check Modem: Ensure your modem is working correctly and has an active internet connection. Try restarting your modem.
• Cable Connections: Verify that all Ethernet cables are securely connected between the modem and the main Deco unit.
• Deco LED Status: Check the LED status on your main Deco unit. A solid green light indicates a healthy connection. If it's red or pulsing, refer to the Deco app for specific error messages.

Weak WiFi Signal or Dead Zones

• Relocate Deco Units: Try moving satellite Deco units closer to the main unit or to a more central location within the problematic area.
• Obstructions: Ensure there are no major physical obstructions (thick walls, large appliances) blocking the signal path between Deco units.
• Add More Units: For very large homes or homes with many signal-blocking elements, consider adding additional Deco units to expand coverage.
