    HI ,
    thx for your reply.
    I using firefox as browser and i don't know with other one.
    But when the problem appears all of http / https web site are not reachable.
    I didn't try too but i tink that other protocol like pop ... have the same problem.

    Yesturday i try with a wire directly connected to my box and no problems appears, so i think that the problem is only on wifi.

      If you get nothing when you issue:
      ping Google.com
      then try
      ping 8.8.8.8
      If that responds then your DNS is fouled up.
      Try restarting your network service:
      sudo /etc/init.d/networking restart

        Hello

        So when my appeared when i launched the download a software in Muon.
        I try some of your solution. And immediatly after the connection of a the ethernet wire i was able to go to the internet :

        Here you can see my interfaces file :

        auto lo
        iface lo inet loopback


        Heresome test :
        ping ww.google.com : unknow host www.google.com
        ping 8.8.8.8 : From 192.168.1.95 : icmp_seq=1 Destination Host Unreachable

        And the commande : sudo /etc/init.d/networking restart doesn't change anything.
        When i launch this command nothing was writen into the console.

          Do you get wifi on any other device; cell phone, tablet, etc? If you have no other device, have a friend try to receive wifi in your home.

                  As I said previously the problem appears after a simple download or launching a video on Youtube (when I ask too much internet)

                    Ah, the RTL8* wifi. My PC has a similar model RLT8188CE.

                    First, create the following file as root:
                    /etc/modprobe.d/rtl8723be.conf
                    then add the foilowing line:
                    options rtl8723be fwlps=0 ips=0

                    My .conf file has the following line in it:
                    options rtl8192ce ips=0 swlps=0 fwlps=0

                    They turn off link and FW power contral saves, which are on by default.
                    The two other possible settings are off by default.


                    The following solution only works for Trusty:
                    Code:
                    sudo add-apt-repository ppa:hanipouspilot/rtlwifi
                    sudo apt-get update
                    sudo apt-get install rtlwifi-new-dkms linux-firmware
