    Ethernet Adapter Not Responing

    Hello,

    I have a Dell XPS M1210. Ethernet adapter seems to be Broadcom Corporation BCM4401-B0 100Base-TX (rev 02).

    When connect an ethernet wire with internet access, there seems to be no response whatsoever (lights on adapter itself not working and no connection established), whereas with same computer on Windows operating system (I used to have windows and switched to Ubuntu) adapter and connection worked fine.

    Here is output of:

    ~:$ lspci | grep -i eth
    Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)

    ~:$ ifconfig eth0

    Could there be a problem with my driver? Or could the driver somehow be blacklisted in /etc/modprobe.d/?

    Any help would be much appreciated.

    Kind regards.

    Re: Ethernet Adapter Not Responing

    For some reason in the kernel a network boot is checked for first on the boot up. If this network boot fails sometimes the ethernet is disabled. While appearing to work.

    Go to your bios, and place network boot to the top of the boot list. Save and exit. This will cause your boot up to be about 3 seconds slower. Also you have to click [ctrl]+[c] to cancel the network boot each time. But this workaround has worked for me in the past and many others.

    Re: Ethernet Adapter Not Responing

    Many thanks for your help and prompt response - really appreciate.

    I am afraid the suggested solution did not work. I did the following:

    (i) Went to system bios (by pressing function key F2 at bootup - this is what works for Dell XPS M1210).

    (ii) Went to boot sequence, which looked like this:

    1. Discette Drive
    2. Internal HDD
    3. USB Storage Device
    4. CD/DVD/CD-RW Drive
    Onboard NIC

    (iii) Moved Onboard NIC first in the list, and enabled it (by pressing Space), so now boot sequence looks like this:

    1. Onboard NIC
    2. Discette Drive
    3. Internal HDD
    4. USB Storage Device
    5. CD/DVD/CD-RW Drive

    (iv) As you suggested, device slows boot time but still boots. Yet even after boot, ethernet connection shows no sign of life.

    Thanks much.

    Re: Ethernet Adapter Not Responing

    Ok well undo what I previously stated. No point slowing your boot up if it doesn't work as a workaround anymore.

    How long ago did you have Windows installed? No lights usually means hardware problem. Meaning the wire you are using could be damaged or the ethernet connection it self.

    Take out the onboard NIC.
    And unless you plan to add another OS, take out everything else. his speeds up your boot time and prevents mistakes.
    It worked for me, and if it didn't I wouldn't share it.
    Actually, go to ADVANCED->And make sure the Onboard LAN is not [Disabled]

    Re: Ethernet Adapter Not Responing

    OK thanks to both for your responses and help.

    I reverted back to previous boot sequence and disabled ones I do not use, as suggested by both.

    Problem of-course still remains. It used to work on Windows, which I completely deleted 5-6 weeks ago now, so I guess it may be a hardware issue after all.

    By the way, not sure where Advanced is to check whether Onboard LAN is Not Disabled - note I am on Ubuntu 12.10.

    Thanks for all help - much appreciate.
