What's the best way of increasing my Wi-Fi. In one room I can only get a faint signal due to the thickness of the walls. Currently I have a network cable from the router into a switchbox into the room I want Wi-Fi, but I'm getting fed up with the number of network cables I have lying around. 1 x Acer Revo 1 x Desktop PC 1 x Laptop. I've looked at the AirPort Extreme but isn't there a cheaper option which allows me to connect a network cable from the router to the extender and then improve the Wi-Fi signal in that room.
