I do not know what the other reviewers have, but only under Windows Vista before felt 100 years I had problems with this card. Under current operating systems like Win7 or Win8.1 these WLAN card runs with 3 antennas for improved range and better signal without any problems. I'm super happy and for some years already. So much hatred deserves not the product.
Windows automatically loads the appropriate drivers from the driver library and it just works. Had before a Allnet card and has prepared an excessive number of problems. That was really annoying.
