    Please do the following:

    - open a terminal window by clicking on Applications, then down to Accessories, then over to and click on Terminal

    - type:

    lspci <press enter> copy this information and paste it back in a reply here (hopefully you have a USB flash drive or something you can copy it to)

    lsusb <press enter> copy this information and paste it back in a reply here (again, hopefully you have a USB flash drive or something you can copy it to to take it to the Windows machine you are posting from)

    lshw -C network <press enter> Ditto - copy and paste back in a reply.

    We need to identify what adapter you have and the chipset it is using before we can direct you to anything helpful.

    Re: Dell Wireless Wlan card not working

    The easiest way to get your wireless drivers is to connect to your router with an ethernet cable and use that connection to install wireless drivers from System -> Administration -> Hardware Drivers

    If that's not an option, then I need to know your wireless card model number to give you altenrative instructions. You can find out by opening a terminal and pasting this command:
    Code:
    lspci | grep Wireless

    Wink Re: Dell Wireless Wlan card not working

    EDIT-2: I just noticed from the lshw -C network that it is showing b43 as the driver for the wireless. Check in network manager to be sure you have "enable wireless" checked, then check again to see if you see any networks available. If not, please do the following in a terminal window and post it back here:

    lsmod <press enter>

    ----- END OF EDIT-2 -----

    Ok, from the lspci (which means list all pci devices), we get:

    0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

    This is your wireless. Check under System/Administration/Hardware Drivers and see if there is a driver listed there and if so enable it. If that isn't available or it doesn't work, do you have the ability to hard-wire a connection from your PC to the router? If so, use it and do the following ( I *think* this is what people do to get the "built-in restricted driver):

    - open a terminal window again

    - type:

    sudo apt-get update <press enter>

    sudo apt-get upgrade <press enter>

    Then check under System/Administration/Hardware Drivers and see if there is a driver listed there, and if so enable it.

    If you don't have the ability to access the net via a hard-wired connection, then there is something else we can try as well:

    - locate the Windows driver (should be .inf and .sys files for the adapter). This may come as an .exe and if so you may need to run the exe on your Windows computer just so you can get the files (if so, copy them to a USB stick if you can). Copy the files to your Ubuntu Desktop folder (~/Desktop).

    - place the LiveCD you used to install Ubuntu back in the drive. Let it "think" a couple of minutes - if it comes up saying a disk with packages has been found and ask if you want to open the package manager, just say no.

    - Click on "Places" and then the drive your CD is in

    - navigate to the /pool/main/n/ndiswrapper folder on the CD. You should find 2 files there - 1 for common, the other for utilities. Double-click these (1 at a time) to install them.

    - open a terminal window

    - type:

    cd Desktop <press enter>

    sudo ndiswrapper -i xxxxxxx.inf <press enter> where that's a lower case "I" (for insert) and replacing xxxxxxx.inf with the actual name of your .inf file you put on the desktop

    sudo ndiswrapper -l <press enter> where that's a lower case "L" (for list). Check the output to be sure it shows your driver and says the device is active.

    sudo depmod -a <press enter>

    sudo gedit /etc/modules <press enter>

    This will call up an editor with the file /etc/modules opened in the window. Scroll to the bottom of that file and add the following line:

    ndiswrapper

    Save the file, exit the editor.

    sudo gedit /etc/modprobe.d/blacklist.conf <press enter>
    This will call up the editor again, this time opening the blacklist.conf file (this file indicates what modules NOT to load on boot). Scroll to the end of the file and add the following lines:

    blacklist b43
    blacklist b43-legacy
    blacklist ssb

    Save the file, exit the editor.

    Now, reboot. After the boot, look in network manager and see if your wireless is showing (you may have to click on "enable wireless" in network manager first).

    Dave

    EDIT: Additions:

    (1) you may need to add "blacklist bcm43xx" to the blacklist.conf file as well.

    (2) be sure you unplug your network cable from the PC (if you can hard-wire a connection to the router) before you try wireless again. While it may be possible (I don't know), I've never had any luck getting both running at the same time.

    Ultra Easy Way

    1) Download this installer . using Windows and copy it to a pen drive.

    2) Boot into Ubuntu, insert the pendrive and extract the archive it and open the resulting folder.

    3) Double Click on install.sh and choose "Run in Terminal"

    4)Follow on screen instructions.

    Re: Dell Wireless Wlan card not working

    Check to see if your getting any wireless signals:

    Code:
    sudo iwlist scanning
    If you are then your wireless card probably isn't the issue.

    unmole, I didn't know that existed - did you create it? Either way around it's a much simpler way of doing things.

    Thanks!
