With the standard built-in antenna, or a card-mounted "rubber ducky" antenna,
not likely. At that distance, you will need a directed antenna carefully
aimed at the AP. I've used such a setup across distances up to 7 miles
(about 10 km) with a 24db "fruit basket" antenna and no amplifier.
The good news is the antennas are really cheap. The bad news is the Low-Loss
coaxial cable you'll need to connect your system to the antennas is very
expensive.
