What is the average range of wifi equipment?

The average range of Wi-FI equipment to access internet used to be between 100 to 700 feet. Last year, the company hField Technologies introduced to market the device called Wi-Fire that extends the range to 1000 feet.

unless you live near water ie. lakes,or a bay, I live at least 2000 feet from the yacht club and my computer connects to their router automatically.
