There is an ongoing problem with dropouts with this adapter - check the support forums on the intel website. If you have one, make sure you turn off power saving mode. Because it is dual band (2.4 GHz and 5.2 GHz) and offers both "G" and "N" modes, it is difficult to tell from the submissions what the problem really is (as everyone is, unknowingly, using the card differently) and whether it is only a driver problem, or actually a hardware problem. (perhaps a conflict between Bluetooth 4 and one of the WLAN radios?). As it is now 9 months since the launch of the card (August 2012 -> April 2013), one begins to suspect the latter.
