    Re: Wired ethernet not getting detected

    Are there plans to include the wired part of the patch in any of the kernel updates? And if I use this method (from the compat wireless team) what are the drawbacks?

    Getting compat-wireless on Ubuntu

    With Ubuntu you have the option of either installing compat-wireless yourself or of installing the package that provides it built by the Ubuntu kernel team. The Ubuntu package that carries compat-wireless is called linux-backport-modules and it has more backported modules than just your wireless subsystem. Its updated whenever major updates are pushed out into the wireless-testing git tree.

    # For Ubuntu 8.10 Intrepid users:
    sudo apt-get install linux-backports-modules-intrepid

    # For Ubuntu 9.04 Jaunty users:
    sudo apt-get install linux-backports-modules-jaunty

    # For Ubuntu 9.10 Karmic users:
    sudo apt-get install linux-backports-modules-karmic

    # For Ubuntu 10.04 Lucid users (one of the following depending on the installed kernel. Most user should choose generic):
    sudo apt-get install linux-backports-modules-wireless-lucid-generic
    sudo apt-get install linux-backports-modules-wireless-lucid-generic-pae
    sudo apt-get install linux-backports-modules-wireless-lucid-preempt
    sudo apt-get install linux-backports-modules-wireless-lucid-server

    I'm not sure whether the backports-modules packages would provide the ethernet driver you need. You can always install it, reboot and test; it's easy to uninstall later if it doesn't help.

    I can't really think of any drawbacks to installing the backports-modules packages, other than that I'm not positive whether they would contain the driver you need.

    Also keep in mind that if you upgrade to 10.10, your ethernet should work out-of-the-box there, because the 10.10 kernel has the right driver built in.

    Re: Wired ethernet not getting detected

    The reason for staying with 10.04 is keeping all of my customers on the same page, in the past they were spread out over many different releases which meant that I had to keep several different releases on my laptop. As a matter of fact the 8.04 release has the same problem with the ath9k driver, which is present on my laptop, I believe I will try the backports module on it to see if it holds my wireless driver in place without having to reinstall.

    Re: Wired ethernet not getting detected

    If I reinstall the present kernel will that be sufficient to test whether or not the driver will hold in the future?

    Sorry, I'm not positive what you mean. Are you referring to the non-backports kernel, or the Ubuntu 10.10 kernel that you would install on Ubuntu 10.04, or something else?

    I agree that staying on Ubuntu 10.04 makes sense if you've got a broad range of machines to support. It's LTS anyway.

    Re: Wired ethernet not getting detected

    Hello, I'm running into trouble with my wired internet connection and I thought I would post to this thread, as I think my problem is more or less related.

    I'm using Ubutu 10.4 LTS 64 bit edition and recently after a restart my wired internet connection stopped working. I am connected to the internet via LAN and when I am in Ubuntu, the orange light in the back where the ethernet cable is plugged in is blinking even though I don't have internet connectivity. I have a dual boot machine and I can access the internet via Windows XP. Furthermore I have used this computer and connection for over 3 years now and have never had this problem before. Also, I'm not using wireless and never have, just the wired LAN connection.

    When in GNOME I go to System -> Preferences -> Network Connections in the Wired tab I see Auto eth0 and in the column 'last used' it says 'never', which is strange since I have used it pretty much every day for over three years.

    I looked at various forums online and it seems that other people have the same problem, however I could not find the solution. Here are various posts on the matter:

    http://ubuntuforums.org/showthread.php?t=1487820
    http://ubuntuforums.org/archive/inde...t-1073970.html

    I also tried booting from previous versions of the kernel from the list when Ubuntu starts up, however to no avail.

    Below I provide the outputs for the commands which were asked in previous posts in this thread:

    ----------------------------------------------

    When I read this thread, I followed the advice given in post #6, however my internet is still not working. That's why I ran followed post #32 and ran sudo make uninstall.

    I guess the reason why it the proposed solution didn't work is that my problem is slightly different. My internet connection was working fine for 3 years (I started with ubuntu 7.10 and upgraded to every single new version) and suddenly it stopped working now. In addition my hardware is different, if I read the commands correctly my internet interface is "NetXtreme BCM5754 Gigabit Ethernet PCI Express". If anyone has any suggestions what I should do to fix my problem, it would be greatly appreciated.

    If all else fails and I decide to reinstall Ubuntu, is there a way to do that without reformatting my harddrive? In other words would I lose all my documents, such as my old emails stored in local folders in Thunderbird as well as bookmarks in firefox?

    Thanks a lot for your help!

    PS. If my problem is different than the one discussed in this thread, I'll be happy to repost a new one.

    Re: Wired ethernet not getting detected

    jopeto: yes, I think your problem is different than the others in this thread. The problem of other posters had to do with Ubuntu not having a driver available for their ethernet hardware (which was different from the hardware you have), so they had to compile a driver manually. In your case, the device is being brought up and it doesn't appear like the driver is the issue.

    The one thing in the output you posted that looks out-of-place to me is the line in the nm-system-settings.conf file that reads "no-auto-default=00:1a:a0:65:a8:97," As I understand it, that line would normally tell the system not to manage your ethernet connection, which could certainly be the problem.

    So, I'd suggest opening up the configuration file by typing:
    Code:
    sudo gedit /etc/NetworkManager/nm-system-settings.conf
    Then put a hash (#) in front of the line in question so it looks like:
    Code:
    #no-auto-default=00:1a:a0:65:a8:97,
    This will comment it out so the system will ignore that line, but leave it there so you can always uncomment it later if you need to.

    After this, save the file, then reboot your computer. Do you have better luck now? If not, we can try some other things.

    By the way, you're positive you use dynamic IP addresses served via DHCP and not static ones, correct? If you don't know what this means, you probably use DHCP.

    Re: Wired ethernet not getting detected

    Hi pytheas22, thanks a lot for your quick reply!

    I just tried your suggestion by commenting the above line, however unfortunately that didn't solve my problem. I still cannot connect to the internet.

    Yes, I am quite sure that I am using a dynamically assigned IP address via DHCP. I can double check that on Monday and will get back to you in case I'm wrong.

    One additional piece of information - I just tried booting from the Ubuntu 10.4 LTS 64 bit live CD and I could not connect to the internet even in that case. Then I booted from the same live CD from a different computer connected via the same ethernet cable and I could connect to the internet without a problem. I'm wondering if there is some problem with the hardware address of my computer on the network, but I cannot check that before Monday as well.

    If in the meantime you have any suggestions please let me know.

    Thanks a lot once again for your help!

    Re: Wired ethernet not getting detected

    jopeto: hmmm, that is very bizarre that it doesn't work under a live CD either. I wonder if you could connect if you spoofed your MAC address, so that the hardware address of your computer would appear different on the network.

    You could change the MAC by typing:
    Code:
    sudo ifconfig eth0 down
    sudo ifconfig eth0 hw ether 00:26:b9:06:2a:e2
    sudo ifconfig eth0 up
    This should change the MAC address to 00:26:b9:06:2a:e2 (which is just a random one I made up). You can verify that it's changed correctly by typing "ifconfig eth0".

    With the address changed, try connecting (using either NetworkManager or "sudo dhclient eth0" from the command line). Any luck?

    Hi pytheas22,

    Thanks once again for your suggestion. I tried it but unfortunately spoofing my MAC address didn't work either (neither when I booted from the hard drive nor when I booted from the live CD). Tomorrow I'll check with the network guys whether there is some problem on their side and will also take my computer home to check whether I can connect to the internet there. I'll let you know.

    Thanks once again for your help!
