    Internet Connection - none

    I've been using Ubuntu since Breezy and have never experienced this problem.
    I have a desktop PC which I built last year.
    I'm connected to Internet by DSL modem/router.
    3 other PCs are also connected and work fine.
    I successfully ran #! (Crunchbang) for a while.
    Also Puppy.
    No connection problems with either.
    Never installed M$ Windoz on this box.
    No duel boot, just one distro installed at a time.

    But when I install Xubuntu 12.04 there is no Internet connection.
    I installed it twice, with #! inbetween.
    Earlier Xubuntu worked fine in Virtual Box (in #!).

    I ran the following two tools:

    dmesg | grep eth
    [ 0.311293] i2c-core: driver [aat2870] using legacy suspend method
    [ 0.311294] i2c-core: driver [aat2870] using legacy resume method

    [ 9.944074] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

    and

    ifconfig
    eth0 Link encap:Ethernet HWaddr 00:30:67:c7:a1:ce
    inet6 addr: fe80::230:67ff:fec7:a1ce/64 Scope:Link

    collisions:0 txqueuelen:0
    RX bytes:759876 (759.8 KB) TX bytes:759876 (759.8 KB)

    When I run ifconfig with other distros installed
    I get my IP address and they connect fine.
    As you can see, no IP address here!

    What do I need to do to get connected to the Internet.

    Thanks in advance.

    It would appear that dhcp is not working for you. Make sure that dhclient is installed, use:

    aptitude search dhclient

    to check the current installation status.

    Thanks,

    I tried your suggestion and got nothing,
    but some very quick flashes of ????
    and my prompt back.

    Do I need something like
    apt-get install dhclient
    ?

    Rebooted - no change.

    Re: Internet Connection - none

    Sorry, my bad. dhclient is not the name of a package. To see the owner of the dhclient command, see the output of:

    dpkg-query --search dhclient
    < . . . bunch of other stuff . . . >
    isc-dhcp-client: /sbin/dhclient

    then use aptitude (or apt-get):

    aptitude search isc-dhcp-client
    i isc-dhcp-client - ISC DHCP client
    p isc-dhcp-client:i386 - ISC DHCP client
    p isc-dhcp-client-dbg - ISC DHCP client (debugging symbols)
    p isc-dhcp-client-dbg:i386 - ISC DHCP client (debugging symbols)

    The leading 'i' means the package has been installed.

    Similar problems with Xubuntu 12.04 fresh install here. I think networking worked during the installation, but after rebooting eth0 doesn't respond:
    Code:
    # ifup eth0
    error: "net.ipv6.conf.eth0.999.accept_ra" is an unknown key
    failed to bring up eth0
    
    # dmesg | grep eth
    
    # lspci | grep Net
    00:19.0 Ethernet Controller: Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02)
    
    # ifconfig
    lo        Link encap:Local Loopback  
              inet addr:127.0.0.1  Mask:255.0.0.0
    ...etc
    Tried it on two separate machines and no network to speak of. Don't see any bugs filed under Xubuntu.

    This is the first similar thread I've found. Did the original poster find a solution?
