For installation / configuration under Raspbian Wheezy:
For me, the adapter was immediately recognized by the system, there was no driver installation required. Perfect!
There were problems, however, when connecting to the network. Inexplicably, a device did not work by iwconfig. After some research, I've found the solution: a fixed setting in the / etc / network / interfaces file
So it might look at a WPA2 connection:
# The loopback network interface
Car Lo
iface lo inet loopback
# The Ethernet network interface
iface eth0 inet dhcp
# The WIFI Network Interface
auto wlan0
iface wlan0 inet static
WPA SSID wireless SSID
WPA-PSK WLAN password
WPA-PSK WPA key_mgmt
address IP-address-of-PI
netmask 255.255.255.0
Network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
Depending on the network, can at network, broadcast and gateway the first three IP blocks look different (eg 192.168.178.0, 192,168,178,255 and 192.168.178.1).
I am satisfied with the adapter and can recommend it for use on Raspberry Pi.
