I tested the wi fi signal strength from an Xfinity router using a Cornet ED78S RF meter before placing the router in the cage. The signal was full strength red in the danger level from 4 feet away. After placing the router in the cage and properly routing the wires and cables the signal was now in the green (as low as it could go) from 4 feet away.
