I had to make the changes shown in this answer to get this interface to come up automatically after a reboot. The driver for this adapter was already in the Raspbmc kernel. It is my understanding that this driver is also in Raspbian Wheezy.
Here's a link to known working USB WiFi adapters for the Raspberry Pi.
I am running Raspbian on my Pi, and I use an 'RTL8192cu' based USB WiFi adapter.
Configuration was easy:
sudo nano /etc/network/interfaces:
(modified for your wireless network settings, of course)
auto lo iface lo inet loopback iface eth0 inet dhcp auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-scan-ssid 1 wpa-ap-scan 1 wpa-key-mgmt WPA-PSK wpa-proto RSN WPA wpa-pairwise CCMP TKIP wpa-group CCMP TKIP wpa-ssid "MYNETWORKNAME" wpa-psk "MYNETWORKPASSWORD" iface default inet dhcp
When the Pi comes up it should automatically connect to your wireless network.
If it does not, you can check and see if there is an existing discussion for your specific hardware, software, etc.
