When I connect devices to the wireless network they do not connect to the deco closest to them. My fire stick in my basement keeps connecting to the deco on the second floor. My ring outside in the garage connects to the deco in the basement unit all the way across the house and down a floor. I am not getting good enough signals to use the devices. How can I fix this or I will need to return these decos for something else as they are worthless if I can't get good signals.
