Any ideas? Is the AirPort Card just weaker? You didn't say whether the PCs have any part of their cards exposed outside of their cases. Are the cards being used in the PC laptops the PCMCIA variety? Do they have an external portion of the card that sticks out of the PCMCIA slot? It is very probable that those cards have their antennae concealed in the portion that protrudes outside the laptop case. In which case, they would have the benefit of a more sensitive antenna than the Mac laptop. My PC laptop (used only at work to learn how to run WhineDoze) has an internal wireless card and does not get any more signal strength than my Pismo with an Apple Airport card installed. My Wallstreet with an Orinoco PCMCIA wireless card inserted gets two bars more signal strength when I go outside the building. From this, I would suggest that your difference in signal strength and performance is more dependent on the external antenna that a PCMCIA card sticks outside the laptop case.
