I'm using Ubuntu 13.04 3.8.0-27-generic and I cannot use my TL-725N nano wireless adapter.

I installed this : https://code.google.com/p/realtek-8188cus-wireless-drivers-3444749-ubuntu-1304/
But nothing appened, even after reboot. I still can not see the device in the network manager.

sudo modprobe r8712u did nothing and here is the result of iwconfig:
