    Hello Aziz, welcome to the forums

    Please post the outputs of the following -
    Code:
    uname -mr
    lsb_release -d
    And can you connect to internet using a wired connection to download some packages? You seem to have correct driver loaded for your ethernet interface, so cable connection should work.

    Re: Problems with internet in Toshiba satellite C855.

    Please try what is suggested here : http://askubuntu.com/a/165002

    However, if you can't get your wired connection to connect to internet, then we'll have to do a little more work. In that case, proceed as follows:

    1. To download the packages on a different computer :
      Code:
      sudo apt-get install --print-uris build-essential linux-headers-generic linux-headers-`uname -r`
    2. This command will, among a few other details, give you the download links for each package. Copy them in a text file and use them to download the packages on another computer. Then copy them to your Ubuntu computer and double-click to install.
    3. Download the driver from this link : http://dl.dropbox.com/u/57056576/DRI...14.2012.tar.gz
    4. Copy the downloaded .tar.gz package to your Ubuntu computer desktop, then "Right-click on the package > Extract here". This will extract the downloaded package to a folder with the same name as the package (rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.051 4.2012).
    5. Once successfully extracted, open a terminal and run the following commands in it (one command at a time > let it finish > run the next command....) :


    Code:
    cd ~/Desktop/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
    make
    sudo make install
    sudo modprobe -v rtl8723e

    If, while compiling the driver, you get this error :
    .....error: ‘IEEE80211_HW_BEACON_FILTER’ undeclared (first use in this function)
    Then you may need to do a little modification in the source code as mentioned here (post #36) : http://ubuntuforums.org/showthread.p...1#post12331931

    For reference : http://askubuntu.com/a/154935

    Let us know how it goes.
