I had a similiar problem that you described. My Linksys WRT54GS was
next to the cable modem in the basement. As as result, half of my
house had essentially no signal. I played around with signal boosters
at the basement AP, however, they do nothing to improve the signal from
the laptop back to the AP. A wireless card with a directional antenna
may work for you since the computer will be a desktop, however, for my
laptop it didn't seem practical.
My solution was to buy another WRT54GS and use it as a repeater. I
installed the latest Sveasoft Alchemy firmware on both units which was
easy. In the Sveasoft forum there are "how to'" guides to set up the
second router as a repeater. The whole thing took my about 1 hour to
set up. The end result...I can plug the second router (repeater) into
any outlet on my first floor and it rebroadasts the signal to the rest
of the house. No part of my house is weak. Encryption/security is
unaffected. The transmission rate is half'ed, however, I notice no
practical diference. I love it.
