Upgraded to this Card from a non-Rev A. card and was getting consistant DL speed of 1.4-1.6MB This speed of course is achived when used in area where you get good signal. I've used this card for about 6 months and I can only remember 1 time where it used National access in stead of broadband access(most of times, even with low signal, it still connected Broadband access) 100% satisfied with this product.
