    Wired Ethernet card not detected

    I have installed Ubuntu 10.04 on a Dell Optiplex 990 desktop, dual-booted with Win7. There is no network connection on Ubuntu, tho it works under Win7.

    Here are some results from Terminal:

    ========================
    ifconfig -a
    lo Link encap:Local Loopback
    inet addr:127.0.0.1 Mask:255.0.0.0

    ========================

    Perhaps it is the case that no driver is present for this network card in 10.04. I did download the file e1000e-1.10.6.tar.gz from Intel (for the Intel 82574LM network card = VEN_8086, DEV_1502), but I'm not sure it's what I need, nor do I know how to install it to try, or for that matter, how to uninstall it if I need to.

    Thanks!

    If you live-boot from CD (or USB) Ubuntu 11.10 or 12.04 (=beta), what's the output of those commands?

    The card works with 12.04:

    OK, good. Apparently your network hardware is newer than Ubuntu 10.04.

    So ... problem solved?

    Rationale: I'm implementing FOGProject for an imaging application. FOG is known to work with 10.04 (http://www.fogproject.org/wiki/index...Installation). I thought it would be more straightforward to use that version and install any extra driver needed, rather than embark on qualifying/debugging FOG in a more recent environment. After all, 10.04 is LTS until next April. Still looking for the steps to install the driver, thanks.

    That's a very pragmatic solution! The same way I would do it!
