    No internet on 12.04 alternate install

    Hi, while this question may be a bit beyond the scope of this section, I am pretty new to linux so I figured I would post it here. Feel free to move it if you feel inclined to do so.

    I installed 12.04 (32 bit) with the alt installer, and it doesn't seem to have installed any kind of NIC driver (both wired and wireless do not work)

    when I start up with 12.04 live cd, the internet works fine.


    Any help?


    edit: I should also mention the follwing

    Welcome to the forums!

    I'm afraid I have no experience with an alternate install, but my guess is that you simply don't have the drivers installed. You could probably install them by booting from the HD, inserting the CD, making sure the CD is enabled as a software source (In Software Center, Edit>Software Sources), and installing them from the CD.

    Unfortunately, I'm not sure exactly which driver package you need...

    Whilst the process is different, the resulting install is, as far as I know, no different to the one you get from the GUI installer. I don't think the fact that it was the alternate installer makes that much difference to the problem.

    I see. Thanks for clearing that up for me.

    Hi ,

    open the file

    Code:
    gksudo gedit /etc/network/interfaces
    and remove ALL lines EXCEPT these
    Code:
     
    # 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
    Save the file and reboot your PC.

    Thanks

    Alright, I did that. When booting up it tried configuring the network.

    The network tab at the top right is no longer there.
