    No wired connection after update to Xubuntu 12.04

    Hi, I searched forums for answer and it seems that there are more similar problems, but I did not find anything I could use.

    I have an old machine running Xubuntu without problems so far. Recently I made an update to new version. Everything is ok, just the net won't connect.

    Please give me an advice, what should I check to find the rootcause? (i have no or little experience with linux).

    My computer uses RTL-8029(AS).

    Thanks!

    just don't type the "/sbin/" part of commands and you will need to use sudo on modprobe

    see post #4

    Added into file /etc/network/interfaces eth0 settings
    Code:
    Code:
    auto eth0
    iface eth0 inet dhcp
    Then restart the network:
    Code:
    Code:
    sudo service networking restart
    Fixed for me

    Re: No wired connection after update to Xubuntu 12.04

    I fond this why trying to a fix a simmilar problem with arch.

    I don't know if it will be of help, but when I ran, "lspci -v" on the system I saw that under my, "Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller" there was no Kernel driver in use listed.

    So I ran "modprobe r8168" and after a few second it began to work.However, this is not persistent.

    I had to assign a manual IP for it to work. Try that if nothing else works.

    Smile Re: No wired connection after update to Xubuntu 12.04

    This seems to happen to me fairly regularly when I do an upgrade in Ubuntu/Xubuntu.

    From 11.10 to 12.04 I lost the ability to connect the wired ethernet to the dsl modem.

    This time I found the problem was because the file

    /etc/network/interfaces

    was not retained in its original form from my previous Xubuntu install

    This works:
    <begin file content>

    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface
    auto lo
    iface lo inet loopback

    # The primary network interface
    auto eth0
    iface eth0 inet dhcp
    <end file content>

    The new install had this line commented out:

    #iface eth0 inet dhcp


    once i removed the hash mark and resaved the file (you have to use sudo gedit or sudo nano, etc to edit the file) and restarted the computer I was online.
