    1

    Download the Deco App

    ~15s
    Search for "TP-Link Deco" in the App Store (iPhone) or Google Play Store (Android) and install the free app. Open it and create a free TP-Link account or sign in if you already have one.
    2

    Connect the Main Deco Unit to Your Modem

    ~25s
    Use the Ethernet cable included in the box to connect one port on the Deco unit to a LAN port on your modem. Plug the Deco into a power outlet. Wait about 60 seconds for it to power on — the LED light will change to indicate it is ready.

    Quick Tip

    Place the main Deco unit as close to your modem as possible. A short cable run reduces interference and keeps the connection stable.

    3

    Follow the App Setup Wizard

    ~16s
    In the Deco app, tap the "+" icon and select your Deco model from the list. The app will scan for your Deco unit and guide you through connecting it to the internet. You will choose your Wi-Fi network name and create a password during this step.
    4

    Add Satellite Deco Units

    ~24s
    Place additional Deco units in rooms where your previous Wi-Fi was weak. Plug each into a power outlet, then go back to the Deco app, tap "Add Deco," and follow the prompts to bring each unit online. The app confirms when each one joins the network.

    Quick Tip

    For the best coverage, place satellite units roughly halfway between the main unit and the room you want to cover. Avoid placing them behind large appliances or inside cabinets.

    5

    Set Up HomeShield and Guest Network

    ~16s
    In the Deco app, go to More > HomeShield to enable parental controls or device protection. Go to More > Guest Network to create a separate Wi-Fi network for visitors — they get internet access but cannot reach your personal devices like printers or smart speakers.

    TP-Link Deco is a family of mesh Wi-Fi systems that provide strong wireless coverage throughout your home by using multiple small units that work together as a team. Instead of one router struggling to reach every corner, Deco units spread coverage evenly so you get a reliable connection in the bedroom, the backyard, and everywhere in between.

    What makes Deco appealing is the price. Deco systems are typically less expensive than Eero (Amazon) or Netgear Orbi while delivering similar coverage. TP-Link offers a wide range — from the budget-friendly Deco M4 (good for smaller homes) to the premium Deco XE75 (handles very large homes and supports Wi-Fi 6E for faster speeds).

    To get started, download the free Deco app on your iPhone or Android phone before you touch any hardware. Search for "TP-Link Deco" in the App Store or Google Play.

    Once the app is installed, open it and tap "Get Started." The app will walk you through every step. Connect your main Deco unit to your modem (the device your internet provider gave you) using the included Ethernet cable, then plug the Deco into power. The app detects it and guides you through naming your Wi-Fi network and creating a password.

    After the main unit is connected, the app will ask if you have additional Deco units. Place them in rooms where Wi-Fi was weak before — a back bedroom, upstairs hallway, or detached garage. Plug them into power and add them through the app one at a time by tapping "Add Deco."

    The Deco app shows you every device connected to your network in real time. You can see your phone, your TV, your smart speaker, and more — all listed by device name.

    TP-Link HomeShield is a built-in security feature that offers parental controls, network quality controls (QoS), and antivirus scanning for connected devices. The basic version is free. An optional premium subscription unlocks more detailed reports and advanced features.

    Creating a Guest Network is straightforward: in the app, go to More > Guest Network and turn it on. Give your guests a separate Wi-Fi name and password so they can access the internet without reaching your main network and personal devices.

    Firmware updates come through the app. When an update is available, the app sends a notification and you can update with one tap.

    If you use TP-Link's Tapo smart home devices (smart plugs, cameras, light bulbs), they integrate with the Deco ecosystem, letting you manage your smart home and your network from the same app.

    Compared to Eero: Deco is generally cheaper for the same coverage area. Eero has a simpler, more polished app and integrates more deeply with Amazon Alexa. For most people, Deco offers outstanding value.
