Unboxing and Preparing for Setup

Begin by unboxing your Tp-Link Deco Be85. Inside, you should find:

  • Deco Be85 units
  • Power adapters
  • Ethernet cable
  • Quick start guide

Ensure you have a stable internet connection and a compatible device such as a smartphone or tablet. Download the latest Tp-Link Deco app from the App Store or Google Play.

Connecting Your Deco Be85

Choose a central location in your home for the primary Deco unit. Plug it into a power outlet and connect it to your modem using the included Ethernet cable for a wired connection, which can improve stability during setup.

Wait for the LED indicator on the Deco to turn solid blue, indicating it's ready for setup.

Using the Deco App for Setup

Open the Deco app and create a Tp-Link account or log in if you already have one. Follow the on-screen instructions to detect your Deco Be85 unit.

The app will prompt you to name your network and set a secure password. Choose a strong password to protect your Wi-Fi.

Adding Additional Units

To extend your Wi-Fi coverage, add more Deco Be85 units. Place them in different areas of your home, ideally within the range of the primary unit.

Follow the app instructions to connect each additional unit. They will automatically sync and optimize your network.

Optimizing Your Network

After setup, access the Deco app to view device status, update firmware, and customize settings. Consider enabling features like:

  • Guest Network: Create a separate network for visitors.
  • Parental Controls: Manage and restrict access for children.
  • QoS Settings: Prioritize bandwidth for important devices or applications.

Troubleshooting Tips

If you encounter issues during setup:

  • Ensure your modem is functioning correctly and connected properly.
  • Restart your Deco units and your device.
  • Update the Deco app and firmware to the latest versions.
  • Check the placement of your Deco units; avoid interference from thick walls or electronic devices.

Final Tips for a Smooth Setup

For optimal performance, place Deco units in open areas, away from metal objects and appliances that emit radio signals. Regularly update firmware via the app to benefit from security patches and new features.
