    Re: Wired ethernet not getting detected

    PYTHEAS22....ya, it's looking like I'll probably move over to 11.10 here pretty soon. I was a huge fan of Lucid as it worked on a old, pretty much worthless netbook of mine for over a year with zero problems. I finally scrounge up enough cash to get this new Aspire One and it turns out 10.04 doesn't seem to work too well on it. Oh well......whatch gonna do.

    I want to thank you, again, for the help. No way I would have gotten as far along as I did without it.

    Cheers

    Re: Wired ethernet not getting detected

    @pytheas22,can you pls tell me the significance of tag
    Code:
    [ifupdown]
    managed=false
    in file /etc/NetworkManager/nm-system-settings.conf.
    I have this set to true and i have been facing frequent Network crashes for Lucid.I have raised a separate thread for my issue,but that has not been of much help.I was wondering whether this tag may be the source of the problem..

    Vote for my Idea

    Re: Wired ethernet not getting detected

    satish_j: I didn't know what that meant exactly, but according to the man page for NetworkManager.conf (type "man NetworkManager.conf"; if that doesn't work try "man nm-system-settings.conf" as the name of the file seems to be different on Lucid):

    [ifupdown]

    This section contains ifupdown-specific options and thus only has effect when using ifupdown plugin.

    managed=false | true

    Controls whether interfaces listed in the 'interfaces' file are managed by NetworkManager. If set to true, then interfaces listed in /etc/network/interfaces are managed by NetworkManager. If set to false, then any interface listed in /etc/network/interfaces will be ignored by NetworkManager. Remember that NetworkManager controls the default route, so because the interface is ignored, NetworkManager may assign the default route to some other interface. When the option is missing, false value is taken as default.
    I gather from that that this is a way to tell NetworkManager not to try to control a particular device. However, it seems that it only takes effect if you add a device name to the configuration file -- by default my file just looks like this:

    Code:
    [main]
    plugins=ifupdown,keyfile
    
    [ifupdown]
    managed=false
    and so even though the managed=false flag is set, it's not doing anything because no devices are mentioned anywhere in the file.

    I guess this is a bit convulted, but hopefully it clears it up. If you still need help with your issue feel free to ask.

    Thanks for the revert,i will try keeping this tag to false and monitor the crash issue on my system for some time.Also,came to know from other threads about NetworkManager.state file which should have enabled=true for networking.
    BTW,can you suggest what logs should be checked immediately after network crashes to check whether anything of relevance be found in them.Ichecked kern.log but it does not capture anything.

    Did you try /var/log/syslog?

However, there's a driver included in the compat-wireless stack that you can use (I have no idea why they included an ethernet driver in compat-wireless, but according to these emails, someone did).

    To download, compile and install the driver, first go to http://linuxwireless.org/download/compat-wireless-2.6 and download the file named "compat-wireless-2.6.tar.bz2" (you can't download it in the terminal because of anti-hotlinking). Save it to your desktop. Then run these commands (the first two commands require that you either have an Internet connection, or have your Ubuntu installation CD enabled as a software repository):
    Code:
    sudo apt-get update
    sudo apt-get install build-essential
    cd ~/Desktop
    tar -xjvf compat-wireless-2.6.tar.bz2
    cd compat-wireless*
    scripts/driver-select atl1c
    make
    sudo make install
    Then reboot. Hopefully your ethernet will work automatically after reboot; if not, run:
    Code:
    sudo modprobe atl1c
    to insert the driver. Let me know how it goes.

    We can probably make your wireless work too, if you're interested.
    I have a Lenovo G470 notebook recently acquired which has an Atheros AR8152 v 2.0 Fast Ethernet (rev c1); the result is that ethernet wired card is not visible (only the wireless card as eth0); operating system is Ubuntu 10.04 32 bits
    I tried to do the steps that you recommended but in the make step I obtain a compilation error:

    make -C /lib/modules/2.6.32-39-generic/build M=/home/lautaro/Desktop/compat-wireless-2012-03-12 modules

    Please, let me know where is my error

    Re: Wired ethernet not getting detected

    tedmar: it's a compilation error, so you might have better luck if you downloaded a different snapshot of the source code (especially an older one). The copy you got could just happen to have a bug in it. At http://linuxwireless.org/download/compat-wireless-2.6/ you can grab copies from a wide range of different dates.

    If that doesn't help, please post the output of:
    Code:
    lspci -nn
    so I know exactly which chipset you have.

    Also, chances are the device would "just work" if you upgraded to a more recent version of Ubuntu, if that is a possibility. 10.04 is not getting a bit old.

    Re: Wired ethernet not getting detected

    hello every one!
    first post here and thank you ubuntuforums.
    this is a bit long, sorry.

    Issues: not recognized by Ubuntu 2.6.38-14
    1. AR8152 v2.0 Fast Ethernet
    2. AR9485 Wireless Network

    I have a laptop Acer aspire 5349-2899 http://us.acer.com/ac/en/US/content/model/LX.RR902.132
    this laptop runs on windows 7 home premium, can connect to the internet both wired and wireless, after a few hours of used and since I already have windows on the other laptop I decided to format the hard drive and give linux a shot ubuntu 2.6.38-14-generic, gnome 2.32.1 was installed, not too happy with unity, I played with the OS a bit, then I tried to connect to router but no wired and wireless card detected tried every possible ways to get online with no luck, I just blew up windows 7. so to be able to get online I used a realtek wireless n usb adapter which was recognized by ubuntu and connected to the internet and I was able to pull the existing wireless card driver to work using the instructions below.


    acer@acer-Aspire-5349:~$ lspci -nnk | grep -iA2 net

    for the wireless card to be detected I followed the instructions provided praseodym here:
    ***http://ubuntuforums.org/showthread.p...7808&page=7***
    from terminal:
    1. sudo apt-get install --reinstall linux-headers-$(uname -r) build-essential
    2. wget http://www.orbit-lab.org/kernel/comp...ss-2.6.tar.bz2
    3. tar jxvf compat-wireless-2.6.tar.bz2
    4. cd compat-wireless-20*
    5. ./scripts/driver-select atheros
    6. make
    7. sudo make install
    8. sudo make unload
    9. sudo make wlunload
    10. sudo make btunload
    11. reboot the laptop
    these steps worked, laptop connects to router linksys WRT54G (tomato firmware) with wireless security WPA on, also connected to internet.

    and for the wired ethernet I used the instructions provided by pytheas22 here:
    ***http://ubuntuforums.org/showthread.php?t=1505697***
    ***first go to http://linuxwireless.org/download/co...ireless-2.6***
    from terminal:
    1. sudo apt-get update
    2. sudo apt-get install build-essential
    3. cd ~/Desktop
    4. tar -xjvf compat-wireless-2.6.tar.bz2
    5. cd compat-wireless-20*
    6. scripts/driver-select atl1c
    7. make
    8. sudo make install
    9. sudo make unload
    10. sudo make wlunload
    11. sudo make btunload
    12. reboot the laptop
    ***these steps worked, wired ethernet detected and can connect to router and to the internet***.

    the issue I'm having is I can't have both wired ethernet and wireless to be detected at the same time after startup. when I install the wired ethernet driver and is detected I lose the wireless connection then the wireless card disappear in the applet panel. It would be nice to have both wired and wireless LAN. please help me get the lan and wlan to be recognized by ubuntu at the same time I'm not going to use both at the same time but it would be nice. if you need more info on the hardware please let me know.
    thank you.
