4. Operating Your Mesh System
4.1 Seamless Whole-Home Coverage
The Deco mesh system creates a unified WiFi network, allowing your devices to automatically switch to the Deco unit with the strongest signal as you move around your home. This ensures a consistent and strong connection without interruptions.

4.2 Ethernet Backhaul
Each Deco X55 unit is equipped with three Gigabit Ethernet ports. These ports can be used to connect wired devices directly to the Deco unit for maximum speed and stability. Additionally, you can use an Ethernet cable to connect Deco units to each other (Ethernet backhaul), which can significantly improve WiFi performance, especially in larger homes or areas with thick walls.
4.3 Deco App Management
The TP-Link Deco app provides comprehensive control over your mesh network. Through the app, you can:
- View connected devices and their status.
- Prioritize devices for optimal performance (Quality of Service - QoS).
- Set up parental controls to manage internet access for family members.
- Monitor network usage and security alerts.
- Manage guest networks.
4.4 HomeShield Security
Your Deco X55 system includes TP-Link HomeShield, offering advanced security features to protect your home network and connected devices. Included features are Home Network Scanner, Parental Controls, and Quality of Service. An optional HomeShield Pro subscription is available for additional features like DDoS Attack Prevention, IoT Device Protection, and advanced parental controls.

5. Maintenance
To ensure optimal performance and longevity of your Deco X55 mesh system, consider the following maintenance practices:
- Firmware Updates: Regularly check for and install firmware updates through the Deco app. Updates often include performance improvements, security patches, and new features.
- Optimal Placement: Ensure Deco units are placed in open areas, away from obstructions and sources of interference (e.g., microwaves, cordless phones, large metal objects). Proper ventilation is also important to prevent overheating.
- Periodic Restart: Occasionally restarting your Deco units and modem can help resolve minor network issues and improve overall stability.
- Cleaning: Keep the units clean and free of dust. Use a soft, dry cloth for cleaning.
6. Troubleshooting
If you encounter issues with your Deco X55 mesh system, try the following steps:
- No Internet Connection: Verify that your modem is working correctly and that the Ethernet cable connecting the main Deco unit to the modem is secure. Restart both your modem and the main Deco unit.
- Weak Signal or Dead Zones: Adjust the placement of your satellite Deco units to ensure they are within optimal range of each other and the main unit. Consider using Ethernet backhaul if possible.
- Device Connectivity Issues: Ensure your device is connected to the correct WiFi network. Try restarting the problematic device. If older devices have difficulty connecting, ensure their firmware is up to date.
- Deco App Not Detecting Units: Ensure all Deco units are powered on and the LED indicator is showing the correct status (e.g., solid white/green for normal operation). Try restarting the app or your mobile device.
- Slow Speeds: Perform a speed test using the Deco app to identify potential bottlenecks. Ensure your internet service provider (ISP) is delivering the expected speeds. Check for excessive network traffic or interference.
- Factory Reset: As a last resort, you can perform a factory reset on a Deco unit by pressing the reset button on the bottom of the unit for several seconds until the LED blinks red. Note that this will erase all custom settings.
