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.
