Typical wifi is 300M (Around 1000ft ) in coverage, but things like walls, and other obstacles dramatically reduce this range. Think of the wifi signal as a bubble emanating form the antenna on the router (AP) . The closer you are to that center of that bubble the better your reception. You may be able to improve reception using cantenna type antennas, which require precise aiming put extend range.
