Setting up a TP-Link Deco mesh Wi-Fi system is designed to be simple, even for non-technical users. The process begins by downloading the TP-Link Deco app on your smartphone and signing in with your TP-Link ID. Once logged in, you connect the primary Deco unit to your modem using an Ethernet cable and power it on.

The app then walks you through creating your Wi-Fi network name (SSID) and password, selecting the Deco’s location, and configuring basic network settings. After the main Deco is set up, you can easily add additional Deco nodes through the app to extend coverage to every room. This ensures seamless, fast, and stable internet connectivity across your entire home with a single unified network.
