Sorry to tell you that we only provide English Service for Global users, so we tried to translate your question into English and continue to help you. I wish your understanding.

What is the hardware version of your Deco M9 plus? For your information, V1 supports the feature to display which client is connected to which deco and which Wi-Fi band. And the Deco units can connect to each other by wired cable or wireless. 

Have a good day.
