Load the driver by hand:

sudo modprobe -v 8192cu
echo 8192cu | sudo tee -a /etc/modules

Oups! Seems that the deb won't install correctly. Didn't se that earliger when I did it through the software cener, but terminal gave me an error

sudo dpkg -i rtl8192cu-tjp-dkms_1.6_all.deb

I got it to work by a github from some guy over at peppermint

sudo apt-get install build-essential linux-headers-generic git

then:
Code:
mkdir ~/RTL8188EU

then:
Code:
cd ~/RTL8188EU

then:
Code:
git clone git://github.com/lwfinger/rtl8188eu.git

then:
Code:
cd ~/RTL8188EU/rtl8188eu

then:
Code:
make

then:
Code:
sudo make install

Restarted and everything works now like a charm. I didn't even do the last part of the guide:

Code:
sudo depmod -a

then:
Code:
sudo update-initramfs -u

then:
Code:
sudo modprobe 8188eu

EDIT: My only problem is that I have NO IDEA of what that github code did. So if the source disappears I'm lost. Or maybe I can just recompile after new kernels?

Hola! Para todos aquellos que estén buscando la solución a esto, a mi me sirvió este artículo.
(Tengo actualmente KUbuntu 13.04 con kernel 3.9.0-030900-generic, y un adaptador TP-LINK WN822N)

http://zauwn.blogspot.com.ar/2013/08/edup-realtek-semicondutor-corp.html

Puntualmente, la parte donde dice:

git clone https://github.com/dz0ny/rt8192cu.git
cd rt8192cu
make
sudo make install

Para que arranque la placa wifi sin necesidad de reiniciar, como ultimo paso hice un:

sudo modprobe 8192cu


Saludos!
Gabriel

Thanksolavjunior, that worked for me TP-LINK's Mini Wireless N USB Adapter (TL-WN723N v2) on Ubuntu 13.04.

I happens the same as you

I think it's because we are using the 64bit version

Yes, Tim Patterson's .deb file only works with 13.04 (and perhaps earlier?) It will not work in 13.10. Have you tried just plugging in your adapter? Mine will sorta work, it'll work for several minutes then stop responding. I've had decent luck stopping wifi via the applet, pause a couple seconds then starting it again. It seems to be dependent on the machine and the wireless access point/router. I also get prompts to re-authenticate periodically. So far I'm having better success with an RTL8192CU device using the native driver.
