What can I say - it runs perfectly. Connected, current driver previously downloaded (Win 7) installed, almost full link quality through a really thick reinforced concrete ceiling through across the whole House. Now according to various Internet DSL speed tests I get thanks to the 802.11n standard (albeit "only" 150 Mbit / s to the adapter) is a compound of almost 29,000 Kbit / s - at a 32.000er connection.
My other computer which is connected to the router via Gigabit Ethernet wired is only minimally faster and reached the 32,000 short. I did not think that the full speed of wireless is there. Since I was wrong probably.
By comparison, the PCI card has been able to establish any connection, had the stick (if it was time constant) always to the 1500 to 2000 Kbit / s (though in 802.11g mode, ie with 54 Mbit / s).
A difference like night and day. I am very satisfied and can only recommend highly that thing, also because of the unbeatable price.
