I received Hfield's WiFire as a gift. Hfield's Wi-Fire use its proprietary directional antenna and sensitive receiver to find and enhance weak WiFi signals. With WiFire plugged in your USB, you can use many free legitimate internet provided by your city, piggy back on at someone's generosity (or ignorance) or share internet with your neighbors. The saving will be at least few hundred dollars per year. The Hfield equipment cost around $59 is comparable to your one month of internet fee. I am indeed flirting with an idea of cutting off my cable internet as well.
