    Question 7.10 -> 8.04 - Lost Ethernet! (DNS ISSUE)

    I just upgraded from 7.10 to 8.04, and promptly lost all connections to my LAN and the wider internet...

    I have two nic cards: an onboard, eth0, and a netgear (GA311, maybe?) gigabit card, eth1. My network/internet comes to eth1. eth0 is currently unused.

    manual network configuration displays both as set up with static IPs; however, when I attempt to access network-tools, and I click configure on either interface, I get:
    Code:
    The interface does not exist
    check that it is correctly typed, and that it is correctly supported by your system

    here are the results of "lshw -C network" and "sudo ifconfig&&iwconfig" :

    Code:

    Re: 7.10 -> 8.04 - Lost Ethernet!

    I changed the ip address of eth0 to 192.168.1.212, then i ran "ifdown eth0" because I don't really need it. i gave eth1 an ifdown and ifup, but no change

    lots of forums have asked for "dmesg | grep eth", so here it is:

    still no connection... any other ideas?

    Re: 7.10 -> 8.04 - Lost Ethernet!

    the other weird thing is that my dd-wrt router (linksys wrt54gl) shows the computer as an "active client" which implies that the issue is not with the setup of the interface, but with the computer's use of said interface.

    Question Re: 7.10 -> 8.04 - Lost Ethernet!

    ping just sits there, and times out... no responses... if i ping www.google.com or http://www.google.com, it tells me that they don't exist (or similar).

    Re: 7.10 -> 8.04 - Lost Ethernet!

    hmmm, not sure if this will work, but lets take the netgear card out of the equation...focusing on just the onboard should be a bit less confusing.

    First backup your /etc/network/interfaces file like this:
    Code:
    sudo cp /etc/network/interfaces /etc/network/interfaces.orig
    Now open your /etc/network/interfaces file

    Code:
    sudo gedit /etc/network/interfaces
    and comment out all lines except
    Code:
    auto lo
    iface lo inet loopback
    save, restart, cross fingers, your eth should automatically get an ip...if it doesn't work you can restore original interfaces file with
    Code:
    sudo cp /etc/network/interfaces.orig /etc/network/interfaces
