    Wired internet not working

    I built a computer for the first time yesterday, and installed Xubuntu. Everything is working fine so far except for the fact that I cannot connect to the internet. When I plug in the ethernet cable, nothing happens. Under Network Connections, there are no connections for me to join. Is there something I need to do to set it up?

    Is your network card recognized, do you see the card when you enter lspci? There are usually lights on the card. Are they blinking?

    My network card is integrated with my motherboard. Yes, it does seem to be recognized in lspci.

    Have a look in Network Manager and see if "Airplane Mode" on top is enabled. This would disable all connections.

    What do you mean by network manager? If you mean the network connections page in settings, there is no airplane mode option.

    Yes. Main Menu - System Tools - System Settings - Networking

    The top line is Airplane Mode. It was enabled at default in my install.

    Re: Wired internet not working

    rfkill list all has no output

    lspci -nn | grep -E 'Ethernet|Wireless' outputs:
    05:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR8161 Gigabit Ethernet [1969:1091] (rev 10)

    More information:
    I ran sudo lshw -class network which outputed *-network UNCLAIMED and a bunch of information about my ethernet controller. I saw on another thread that this is associated with a missing driver.

    Re: Wired internet not working

    what version of Xubuntu? you may be able to use the alx driver from the compat-wireless backport

    Ubuntu now provides a package for this driver.

    To install the driver:

    sudo apt-get install linux-backports-modules-cw-3.4-precise-generic
    sudo modprobe alx
    see http://askubuntu.com/questions/16519...net-controller
