This is actually a pretty good card with a really bad driver. As long as you use the Asus WL-138g driver as others have mentioned you should be fine. I would have given it 4 stars if it came with the Asus driver to begin with. Before you install this driver, I suggest you pull out the card, shut off your computer, then put it back in again. Then boot up your computer and install the driver. I got excellent test results with the Asus driver (measured with the Road Runner speed test).
