Extremely low rate when you arrive to get network

I bought this WLAN key for an older PC lacks WiFi. On two floors above my box at home, this key TV reception WiFi one in ten and when I had it, the flow rate was low (on the order of 40Mbps, knowing that my box has WiFi n) while other WiFi devices perfectly capture the network with almost maximum throughput in the same room.

Stop using the key (I put the CPL for the old PC), I lent a friend who recovered a PC that does not have WiFi, this PC is also installed two floors above its box, and there is even worse. Certainly, the key captures the WiFi network all the time, but output tops out at 21Mbps, and turns most often around 7 Mbps (at this rate, the research update Windows updates are endless, and 3/4 of the sites web does not load properly when they deign to appear). His old Samsung netbook was placed in the same room, WiFi works perfectly to 54Mbps (WiFi g).

Apart from this unbearable loss rate, we must recognize that the installation is very simple, to note that I did not use the supplied connection manager, I have installed the driver and I manage the network using Windows . We regret that the key is not natively recognized by Windows (tested with XP and 7), but installation is very simple.

Despite the simple installation, I highly recommend this product (unless you do abound patience).
