I just used a USB wireless network card that I bought before, very small, 35 yuan also Special free shipping! It works well!
Plug-in to identify, and I use USB cables directly inserted in the notes for power, 500mA can also bring the entire board. (However, you need to plug in the wireless network card before power-on)
With the lsusb command, you can see:

Then use ifconfig To See That wlan0 has already appeared:

So, we only need to do one thing, modify the/etc/Network/interface file:

Auto Lo

Iface lo Inet loopback
Iface eth0 Inet DHCP

Allow-hotplug wlan0
Iface wlan0 Inet static
WPA-SSID the Wi-Fi SSID you want to connect
WPA-PSK your WPA connection password
Address 192.168.1.106 # static IP Address
Netmask 255.255.255.0 # network mask
Gateway 192.168.1.1 # Gateway
Network 192.168.1.1 # network address
# WPA-roam/etc/wpa_supplicant/wpa_supplicant.conf
Iface default Inet DHCP

After reboot is finished, you can.
