I run this stick in the wireless network of a Fritz! Box 7490 and to a computer that runs on both Windows 7 and Ubuntu 14. For both operating systems, the stick in the 2.4 GHz network is functioning properly.
However, is my Fritz! Box also a 5GHz network. Here the stick shows however glaring weaknesses! Occur only in the 5GHz network with this stick sporadically high packet loss. For me as a "gamer" is not sustainable.
Nevertheless, the stick reaches all in all high speeds and is stable. Thus I forgive 4 of 5 stars.
