I use the Actiontec PC750 on my PC.
Actiontec PC750
Had problems at first with no "hot swapping." Only way it worked was to put card in and re-boot. Tech support sucked.
Finally figured out that the drivers 2K was installing (Texas Instruments PCI-1225 CardBus Controller) were wrong.
Changed drivers to "Generic Card Bus Controller" and it works fine now.
