I have a small house with fiber optic cable. The wi-fi reception is poor at one end of the house, about 40 feet away from the router, but with several walls in between. A purchased an AX1500 Wi-Fi Range extender. The third light down does not seem to go on when I relocate closer to the kitchen where the problem is. It works in the room adjoining the router, but there is no problem with reception there. Is there a way to get this to work or do I need a different product?
