Since you asked the question in the most generic way possible, here
are some generic answers:

1. Different hardware
	a. Different wlan cards (as you pointed out)
	b. Different laptops
	c. Different harddrives
2. Different speedtests (java, flash, etc.)
3. Different protocols (802.11[abg])
4. Different settings on the wlan cards (beacons, etc.)
5. Some sort of preference settings (user-visible or not) on the AP
that prefers one card over the other

In other words, you haven't given us nearly enough information to
determine anything useful.


hope this helps,

Doug
