    Load the driver by hand:
    Code:
    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

    Re: RealTek RTL-8188CUs working well-how to

    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?

    Re: RealTek RTL-8188CUs working well-how to

    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!

    I happens the same as you

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

    Code:
    sudo apt-get install linux-headers-$(uname -r) build-essential dkms
    2.
    Code:
    lsmod
    rfkill list
    sudo iwlist scan
    iwlist chan
    cat /etc/resolv.conf
    3. Dowloaded this one
    Code:

    and installed it.

    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.
