directionaly antennas at both ends will easily give you 50m, i have personally 
done about 30km with 25db antennas.

the silly pole antennas with ap's and cards might be 3db if youre lucky.
a directional should give 15db or more. you might also be able to increase the 
output from the AP and from your card.

even a larger pole antenna in the AP will help out.

try walking away from the AP to see how much range you get. if possible 
replaces the AP's antenna and boost its signal.
