extraire l'archive RTL8192xC_USB_linux_v3.4.4_4749.20121105.zip ce qui génère un dossier nommé RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105

sudo apt-get install build-essential

se placer dans le dossier du driver,je suppose que ce dossier est dans le dossier Téléchargements de ton /home

cd ~/Téléchargements/RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105

 sudo sh install.sh

sudo rmmod rtl8192cu

sudo modprobe 8192cu

si le wifi fonctionne,tapes ces 2 commandes

sudo depmod -a

sudo update-initramfs -u

si le wifi fonctionne correctement,fais la suite

gksudo gedit /etc/modprobe.d/blacklist.conf

ajouter à la fin du fichier qui vient de s'ouvrir,une ligne

        User Guide(1) - connecting wireless networking using "Network Manager" GUI utility (For PC Linux)
==================================================================================================================
            (1) Network Manager is a utility attempts to make use of wireless networking easy.

            (2) Notes: if you want to use the following command-line method to connect wireless networking,
                        please disable the "Network Manager", because "Network Manager" will conflict with method of command line .

==================================================================================================================
        User Guide(2) - Using the wpa_cli & wpa_supplicant tools (For embedded Linux)
==================================================================================================================

    Please refer to the document/wpa_cli_with_wpa_supplicant_20091227.doc

        User Guide(3) - Set wireless lan MIBs in Command Line (Legacy command - Not recommend)
==================================================================================================================
This driver uses Wireless Extension as an interface allowing you to set
Wireless LAN specific parameters.

Current driver supports "iwlist" to show the device status of nic
        iwlist wlan0 [parameters]
where
        parameter explaination          [parameters]
        -----------------------         -------------
        Show available chan and freq    freq / channel
        Show and Scan BSS and IBSS     scan[ning]
        Show supported bit-rate         rate / bit[rate]

For example:
    iwlist wlan0 channel
    iwlist wlan0 scan
    iwlist wlan0 rate

Driver also supports "iwconfig", manipulate driver private ioctls, to set
MIBs.

    iwconfig wlan0 [parameters] [val]
where
    parameter explaination      [parameters]        [val] constraints
        -----------------------     -------------        ------------------
        Connect to AP by address    ap                  [mac_addr]
        Set the essid, join (I)BSS  essid                 [essid]
        Set operation mode          mode                {Managed|Ad-hoc}
        Set keys and security mode  key/enc[ryption]    {N|open|restricted|off}

For example:
    iwconfig wlan0 essid "ap_name"
    iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
    iwconfig wlan0 mode Ad-hoc
    iwconfig wlan0 essid "name" mode Ad-hoc
    iwconfig wlan0 key 0123456789 [2] open
    iwconfig wlan0 key off
    iwconfig wlan0 key restricted [3] 0123456789
        Note: Better to set these MIBS without GUI such as NetworkManager and be sure that our
              nic has been brought up before these settings. WEP key index 2-4 is not supportted by
              NetworkManager.

===============================================================================
        Getting IP address (For User Guide(2) & User Guide(3))
===============================================================================
After start up the nic and connect to AP successfully, the network needs to obtain an IP address
before transmit/receive data.
This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS"
command, or using DHCP.

If using DHCP, setting steps is as below:
    (1)check if the WiFi had connected to an AP via "iwconfig" command
        $> iwconfig

    (2)run the script which run the dhclient
        $> ./wlan0dhcp
           or
        dhcpcd wlan0
                  (Some network admins require that you use the
                  hostname and domainname provided by the DHCP server.
                  In that case, use
        dhcpcd -HD wlan0)

        WPAPSK/WPA2PSK - using wpa_supplicant (For User Guide(3))
===============================================================================

    Wpa_supplicant helps to secure wireless connection with the protection of
WPAPSK/WPA2PSK mechanism. Please refer to the document/wpa_cli_with_wpa_supplicant_20091227.doc

Ensuite d'arpès le forum: "il faut mettre le nom du module dans /etc/modules"
Quelqu'un peut-il traduire cette consigne ?

Merci d'avance pour votre aide.
