I installed Ubuntu on my PC alongside Windows 10. On Win10, the internet works fine, but when I'm on Ubuntu, I'm not connected to any networks,
my cable is properly connected, the box is powered on...

Thank you for your help because it's becoming frustrating

Best regards.

    Open a terminal and give the result of these commands: 

    sudo dhclient eth0


    ping -c 1 8.8.8.8


    ifconfig

      For the ping -c 1 8.8.8.8 it gives me Unreachable Network

      So,

      The command was "sudo dhclient eth0" not "sudo dhclient", and from your screenshot, the correct command is actually "sudo dhclient eno1" (to do before testing the ping) (If someone passes by, when did Ubuntu change its interface names?)

      But before that, when you ran your dhclient, we can see the message "blablabla RF-kill blablabla", rfkill refers to the physical button that turns on Wi-Fi. It can be located on the front of the laptop or on the fn+F1 [or F2, F3, etc.] keys, you first need to check if it is set to "on":

      - Either you have a light that turns on when your Wi-Fi is enabled
      - Or you use the rfkill program (basically, "rfkill list")

      Hello,

      Thank you, so I will try dhclient eno1 and give you the result, however, I am on a desktop PC, not a laptop, and I am connected via Ethernet only, so no Wi-Fi.

      So when I run "sudo dhclient eno1" in the terminal, it asks for my password, I enter it, but the problem is that after 10 minutes, nothing is displayed

      rfkill list gives me: 


      0: hci0: Bluetooth
       Soft blocked: no
       Hard blocked: no
      1: phy0: Wireless LAN
       Soft blocked: yes
       Hard blocked: no

    Hello,

    I recently installed Ubuntu 16.04 on a recent laptop, it worked well in live DVD, but once installed, nothing to do. I tried:
    - changing the driver to a non-free one.
    - various manipulations in the terminal.
    - taking a look at the router configuration, but the connection is excellent (ping, noise margin, download speed).

    Nothing to do, tried Fedora, network card issue during installation, tried Debian, I was asked to install some network thing just in case, gave up! Back to Windows 10, maybe the PC is too recent, too bad, Win 10 has too many leaks.

      I forgot to mention that I was on Wi-Fi, no problem with Ethernet.

        Hi,

        You also forgot to specify the exact references of the laptops ;-\
