How to connect a device to my Deco?

Deco supports both wired and wireless connections.

For wireless devices, you only need to search Deco's Wi-Fi name on the client and connect with the Wi-Fi password.

For wired devices, each Deco provides two Ethernet ports on the back for wired devices such as PC, printers, TVs, etc. You can also connect a switch to the Ethernet port to expand the wired connections.

Note: Deco M3W does not have an Ethernet port.


What to do if I fail to connect my devices to Deco?

If you fail to connect to the Deco, here are some troubleshooting suggestions.

  1. Confirm you connect to the correct Wi-Fi network and enter the correct password.
  2. Refer to the link to check whether the device is in the blacklist. If yes, remove it from the blacklist.
  3. Turn off the Fast Roaming feature.

Some old devices may not be compatible with Fast Roaming and fail to connect to the Wi-Fi network. In this case, it’s suggested to open Deco app and tap More -> Advanced. Find and turn off the Fast Roaming feature.

  1. Turn off the 5GHz Wi-Fi network temporarily.

Some smart devices which require configuration with a mobile device may support 2.4GHz Wi-Fi only. They need to be on the same Wi-Fi band with the mobile device during configuration. In this case, it’s recommended to turn off the 5GHz Wi-Fi network temporarily when setting up the smart device. Open Deco app, tap More -> Wi-Fi, and then turn off the 5GHz Wi-Fi network.

  1. Ensure the client doesn’t have a static IP address.


Note: Some Deco models do not support the feature to turn on/off the 2.4G and 5G Wi-Fi network. Thus, you will miss the Wi-Fi switches if adding these Deco models to your existing Deco network. You can power off these Deco units temporarily if you need to turn off the 2.4G/5G Wi-Fi network. And don’t worry, these Deco models will support this feature via firmware updates in the future.
