You get what you pay for. Speed boost is not working and only with compatible router. The signal reception strength is so poor. i have my notebook's wifi card doing better job than this wireless card with same distance from the AP/Router.Do you want wireless; you get it... performance .. yes it is wireless and can remove the wire in your premisesIf you are not expecting more than 50 feet, use this one or else go for other type of adaptors.. use a USB one would be better than these PCI cards... I will never buy a PCI type card anymore..
