I have seen how helpful this page is from others and I am wondering if you have any advice for me. 
It’s a new build house…..a 2 storey with a single long wing attached going outwards. Satellite internet installed in the attic on the gable of the single storey. living area is in the back left of the 2 storey. Again, double block walls between the 2 parts and the alls foiled insulated with hallow core on the second floor. 
I have the Deco E4 but it isn’t strong enough to send around all areas of the house. Any advice
