    So,I have ubuntu 12.04 64 bit installed. As I try connecting to a wireless connection, it asks for credentials and then every 2 minutes it asks for credentials again. Just doesn't connect. Please let me know, if more info. is needed. Would greatly appreciate any help.

    The op has a broadcom card. He/she would be better off with what is found in post 2 and later of this thread.

    Re: Wireless not working in Ubuntu 12.04

    Ok everybody please try this if you are still having the problem, i work on computers and we had lots of Ubuntu users having this problems today, we found a program on Ubuntu Software Center called Windows Wireless Drivers, it lets you install a windows wireless driver for your wireless card. Worked on all the computers we had in. Please try it.

    Re: Wireless not working in Ubuntu 12.04

    Tried the method mentioned in the other thread for the broadcom driver but to no avail. keeps asking me for credentials every 5 minutes. Gets stuck there.

    How do you use the windows wireless driver tool? Do you need to deactivate the broadcom driver and remove all installed packages first?

    Also asks for an inf file? Where do you find that?

    Hi, you do not need ndiswrapper and it is the last option you want to use.

    Did you try this link as recommended by
    bkratz?
    http://ubuntuforums.org/showthread.php?t=1879096
    if so please post
    Code:
    lsmod
    again so we can see what is loading now and:
    Code:
    lspci -nnk | grep -iA2 net
    iwconfig
    rfkill list all
    Thanks

    Re: Wireless not working in Ubuntu 12.04

    Hi please do:
    Code:
    echo "blacklist brcmwl" | sudo tee -a
    make sure you have installed all updates then run:
    Code:
    sudo apt-get install --reinstall bcmwl-kernel-source
    Then reboot.
    Thanks

    Re: Wireless not working in Ubuntu 12.04

    Thanks a lot Wildmanne.
    The wifi connects but after entering credentials for the 1st time, it gets stuck and keep asking me for credentials every 2 minutes till I hit cancel. Problem not yet solved.

    Any other suggestions?
