    Can't connect to wireless; firmware missing

    Hi everyone. I recently installed Ubuntu 10.10 alongside Vista. When I mouse over the "bar signal" with a red exclamation mark, it says "Wireless networks - firmware missing". I have tried numerous Terminal commands to install the firmware after copying it to the desktop, but the last line of the response is always something like "E: device or firmware not found". I know that it's not a problem with my router, because the signal strength is great in Windows. Please help me!
    PS - When I booted Ubuntu from my USB stick before installation, a message came up briefly saying that there was an error with the firmware and I should visit (link)... I did that and downloaded the firmware (from wireless.kernel.org) and copied it to my desktop, but I couldn't install it.
    Thank you so much!

    Re: Can't connect to wireless; firmware missing

    How about telling us what kind of wireless card it is:
    Code:
    lspci -nn
    What kind of firmware is it; what is its name?

    I don't know the name of the firmware that I need. I've tried installing ndiswrapper and b43-fwcutter, but to no avail. How can I find out the firmware that I need?
    Thanks.

    What is it that you copied to your desktop? Perhaps we can install it.

    The easier alternative is to carry your laptop over to the router, get a wired ethernet connection and go to System > Administration > Additional Drivers and let the computer figure out what you need and download it.

    If it's not a laptop, you might do:
    Code:
    dmesg | grep -i firm
    See if there are any kernel messages with clues.

    I'm pretty sure that it was b43 and ndiswrapper. Even when I entered the command "cd Desktop" and then "gksudo nautilus", and then navigated to the files, it still didn't install.
    I have a laptop, so I will do that later today. Let's hope it works!
    Thank you so much for your help!

    Hi chili555;
    I got the drivers that I needed installed today; I just hooked up to a wired connection and Additional Drivers did the rest for me. Thank you so much! I am now connected!
    Thanks again.

    Type it in and press Enter. It is being accepted even though it doesn't show for security purposes.

    Post back if you are still having trouble.
