    Re: Wired ethernet not getting detected

    pytheas22:

    I reinstalled 10.04, had the wireless driver from broadcom site installed first. It worked
    Not sure what I missed the first time. I did not have to load the wl module either. However I followed the instructions mentioned from the broadcom site.

    After a reboot, i then tried getting the wired network to work. I compiled and restarted. The wired works. However after that I can't get the wireless to work again. Since it is not auto loaded, i tried doing it manually again as below.

    sudo insmod wl.ko
    insmod: error inserting 'wl.ko': -1 Unknown symbol in module
    drince10@drince10-laptop:~/Desktop/forums2/hy64$ sudo insmod ./wl.ko
    insmod: error inserting './wl.ko': -1 Unknown symbol in module
    drince10@drince10-laptop:~/Desktop/forums2/hy64$ sudo modprobe wl
    FATAL: Module wl not found.
    It looks like with a Dell 1501 wireless card (broadcom 4313) on Ubuntu 10.04, we can't get wired and wireless to work (without some developer help) due to some compatibility errors.

    One additional observation i would like to make is with 10.04, the access to Internet is slow every time you visit a page. In Firefox, it looks like a dns lookup of the website is done every time, so it says looking up site and after a minimum of 3-7 seconds, it starts the page download. I observed this on both wired and wireless, even in the second installation. Note, this occurs every time we access the website in the same session. I tried multiple sites too. The first time too I had observed it on the wired , but i thought something was wrong with my connection. However with Ubuntu 8.10, both wired and wireless worked smoothly. The reinstallation of 10.04 confirms it.

    I guess I am better off staying with 8.10 (because it has a lower supported kernel version). When I get a 9.10 cd, i could even try that or whenever broadcom site supports the 2.6.32 kernel, i could retry.

    Re: Wired ethernet not getting detected

    gibu: that makes sense and confirms what I had come to suspect. It seems that compiling the ethernet driver for your device modifies the wireless stack in such a way that it makes the Broadcom wireless driver incompatible. Unfortunately Broadcom's driver can be picky about what it needs to work, and since it's maintained by Broadcom rather than open-source developers, it's hard to fix these problems.

    I'm thinking it may still be possible for you to get your wireless and ethernet working at the same time by using ndiswrapper for the wireless. ndiswrapper would drive your card using Windows drivers rather than Broadcom's driver, and it should work even with your modified wireless stack. If you want to give this a try, I'll try to write up instructions if you can point me to a Windows driver for your wireless card, and tell me whether you're using a 32 or 64-bit Linux kernel (if you aren't sure, post the output of "uname -m").

    Of course, if you'd prefer simply to stick with 8.10 at this point, that's completely fine, so don't feel any pressure to try ndiswrapper unless you want to.

    Rajeshtl: the commands you ran installed an ethernet driver for a device that you don't have. I assume you want to get your wireless working; to do that, it should be sufficient to do:
    Code:
    sudo apt-get update
    sudo apt-get install bcmwl-kernel-source bcmwl-modaliases
    echo wl | sudo tee -a /etc/modules
    You may also need to run this command to undo the changes you made before:
    Code:
    cd ~/Desktop/compat-wireless*
    sudo make uninstall
    If this still doesn't make your wireless work after a reboot, please post the output of:
    Code:
    dmesg | grep -e wl -e eth1 -e disagree
    lshw -C Network

    @pytheas22
    First of all I appreciate your reply and Yes I want to make my wireless work..

    first set of commands didnt work.
    here is the output of

    dmesg | grep -e wl -e eth1 -e disagree

    this gave me nothing.

    Re: Wired ethernet not getting detected

    Rajeshtl: what do you mean when you say the first set of commands didn't work? It would be useful to see the output to know exactly what failed.

    Another approach is to run these commands, then reboot:
    Code:
    sudo apt-get update
    sudo apt-get install b43-fwcutter
    At one point you will be asked whether you want to download firmware; make sure to say yes.

    Note that for this to work, you will need to be plugged into the Internet because you need to download files required by the wireless driver. If you have no way to plug into the Internet, let me know and we can try a different approach (but plugging in is much less complicated).

    Re: Wired ethernet not getting detected

    Rajeshtl: it looks like you were not connected to the Internet when you ran those commands. You need to have an Internet connection to download the files you need.

    If it's totally impossible for you to get an Internet connection on this computer, you can do this:

    1. on another computer with Internet access, download the file http://burnthesorbonne.com/files/b43_firmware.tar.gz
    2. use a USB stick or CD to transfer that file to your Ubuntu computer. Save it on your desktop there.
    3. run these commands on the Ubuntu computer:
    Code:
    cd ~/Desktop
    tar -xzvf b43_firmware.tar.gz
    sudo mv b43 /lib/firmware
    sudo mv b43legacy /lib/firmware
    Now try rebooting and hopefully the wireless will work. If it still does not work, please post the output of these commands (some commands may have no output):
    Code:
    sudo rmmod wl
    sudo rmmod ssb
    sudo rmmod b43
    sudo modprobe b43
    sudo iwlist scan
    dmesg | grep -e b43 -e wlan -e firmware
    ls /lib/firmware

    Re: Wired ethernet not getting detected

    The firmware looks like it's installed now, so that's good. In order to connect to networks, you may simply need to type:
    Code:
    sudo ifconfig wlan0 up
    If that doesn't produce any errors, type:
    Code:
    sudo iwlist scan
    You should see a list of wireless networks in range. If you do, try connecting to yours.

    first time when I ran 'sudo ifconfig wlan0 up' it asked for my password and when I typed in it did nothing,then I entered the second one and it gave me this results

    lo Interface doesnt support Scanning
    eth0 interface doesnt support scanning
    wlan0 interface doesnt support scanning: network is down...

    Network is not down...I have a desktop which is working fine.

    THen I typed in the same commands again
    for the first one this time I got SIOCSIFFLAGS: Unknown error 132
    second one gave the same results...

    Appreciate your help...
