What You’ll Need Before Setup

- An active internet connection
Step 1: Download the TP-Link Deco App
- Install the TP-Link Deco app from the App Store (iOS) or Google Play (Android).
- Open the app and create a TP-Link account (or log in if you already have one).
Step 2: Connect Your Main Deco Unit
- Power off your modem (if it’s on).
- Connect the main Deco unit to your modem using an Ethernet cable:
- Plug one end into the modem’s LAN port.
- Plug the other end into the WAN port of the TP-Link Deco X55.
- Power on the modem and wait 1-2 minutes.
- Plug in the main Deco unit—the LED should pulse blue, indicating it’s ready for setup.
Step 3: Configure the Deco via the App
- Open the Deco app and tap “Set Up a New Deco”.
- Select “Deco Mesh Wi-Fi System” and follow the prompts.
- Customize your Wi-Fi settings:
- Network Name (SSID) – Choose a unique name.
- Password – Use a strong password (WPA3 recommended).
- Admin Password – Secure your Deco system.
- Wait for the setup to complete (LED turns solid blue).
Step 4: Add More Deco Units (For Full Mesh Coverage)
- Place the second Deco unit within range of the main Deco.
- Plug it in and wait for the LED to pulse blue.
- In the Deco app, go to “Add Deco” and follow the instructions.
- Repeat for additional units if needed.
Optimal Placement Tips:
- Keep Decos central to high-traffic areas.
- Avoid thick walls, metal objects, and microwaves.
- For the best performance, use Ethernet backhaul (wired connection between Deco units).
