Ideal for homes looking for maximum Wi-Fi coverage with speed and simplicity for every user, Deco replaces the collection of routers and extenders with a smart Wi-Fi system consisting of multiple units working seamlessly together. Deco maintains one network throughout the home, so you only see one network name and need only one network password. It provides the best connection to all your devices, even when you move from room to room, whether you're playing, streaming or browsing. In a few minutes, the intuitive Deco app guides you through an easy setup process that makes every device ready to use and all your devices connected and online. Deco delivers the best possible quality of home Wi-Fi.
The Deco application allows you to switch on both at the same time. However, please note that in case of a conflict, QoS takes precedence over individual devices.
Note: Some Deco models only support QoS devices such as Deco M4 and E4 etc.
If you want to use Deco with your existing router, do the following:
Define a different network name (SSID) and password than in the current network. Running Deco with the same SSID can lead to technical problems.
If possible, disable the Wi-Fi of your existing router. You will then have one SSID for the entire network, with minimal wireless interference. This will ensure a reliable internet connection and trouble-free roaming.
If your router is a combination of a modem and a router from your ISP, contact your ISP for instructions on how to disable its wireless features.
Your ISP may also receive instructions on how to set your device in bridge mode. If so, it is suggested that you configure your router in bridge mode to avoid some technical problems, such as double NAT.
