I have a three level house. My main Deco is in the basement office. I have the Deco on the second floor connected via ethernet backhaul. I assumed the Deco on the third floor would connect wirelessly to the Deco on the second floor, but the third floor unit always seems to be connected to the office (main Deco). Is there any way to force the third floor unit to connect to the second floor unit since it is closer and would have better signal?
