[John Rogers]

Make a drawing of your house, showing electrical outlets. Just connect to the wifi close to your Asus router. Use your laptop, open the network interface to see the bright green indicator signal light. Then slowly walk around to see what happens to the little icon. As lines turn yellow note on the map where it happens and note on the map as the little icon gets weaker and note where it finally turns black.

That is the map to add signal boosters.
