I often use my Macbook Pro out on the deck. Problem is, with my Airport Extreme Base Station hundreds of feet away on the opposite far end of the house, I can hardly pick up a Wi-Fi signal. What is the most effective way to boost the signal strength? I came across a product http://www.macwireless.com/html/products/antennas_boosters/airport_booster_mini.php, but not sure how well it will work. Appreciate any suggestions -- especially from those who have successfully boosted their signal.
