WLAN didn't work out of the box. After installing still no function.
WORKAROUND: To fix it I needed to add 0bda:819a by hand like descripted in:
http://forum.ubuntuusers.de/topic/rtl8188cus-wlan-kartenicht-erkannt/
Unzip the driver and install it by hand
$cd RTL8188C_8192C_USB_linux_v3.4.4_4749.20120806/driver/rtl8188C_8192C_usb_linux_v3.4.4_4749.20120730
$make
$sudo make install
$ modinfo 8192cu | egrep 'versi|filen|819'
filename: /lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/8192cu.ko
version: v3.4.4_xxxx.20120730
srcversion: FBF2DAF9D4C1BB74C28D37F
alias: usb:v0BDAp8191d*dc*dsc*dp*ic*isc*ip*
vermagic: 3.2.0-36-generic SMP mod_unload modversions
parm: rtw_chip_version:int
for the next step I needed vendor:product ID from lsusb:
$lsusb
Bus 001 Device 006: ID 0bda:819a Realtek Semiconductor Corp.
and then add this ID like here:
$ echo 'install 8192cu modprobe --ignore-install 8192cu ; /bin/echo "0bda 819a" > /sys/bus/usb/drivers/rtl8192cu/new_id' | sudo tee /etc/modprobe.d/8192cu.conf
install 8192cu modprobe --ignore-install 8192cu ; /bin/echo "0bda 819a" > /sys/bus/usb/drivers/rtl8192cu/new_id
$ sudo modprobe -v 8192cu
install modprobe --ignore-install 8192cu ; /bin/echo "0bda 819a" > /sys/bus/usb/drivers/rtl8192cu/new_id
insmod /lib/modules/3.2.0-29-generic/kernel/drivers/net/wireless/8192cu.ko
