Hi, 
For the reported phenomenon, please provide the following information for further analysis.

  1. Please describe your network diagram. Are the two satellite Deco wirelessly connected to the main Deco?
  2. When the connection drops on your client device, what's the LED status on the two satellite Deco? Are the client devices connected to the Deco's Wi-Fi but have no internet connection, or are they disconnected from the Wi-Fi?
  3. Do you have the same phenomenon when connecting to the main Deco's Wi-Fi?
  4. How often do connections drop on your client device, such as how many times a day? Do all client devices drop connection at the same time?
  5. Please refer to the instructions below to send us the Deco app log. After that, please attach your reference number (such as email TKIDXXX) to this thread so we can find your app log.
