    Cool Wireless connection with "WPA2-PSK [AES]" security cannot be established anymore

    After upgrading to 12.04 from 11.1, wireless connection with "WPA2-PSK [AES]" security cannot be stablished anymore.
    My power line network only supports
    "WPA2-PSK [AES]"
    OR
    "WPA-PSK [TKIP] + WPA2-PSK [AES]"

    Ubuntu 11.1 was working perfectly fine with that but now it cannot make a connection. I am however able to connect to another wireless network with "WPA-PSK(TKIP)" security.

    Is there any solution for this problem? I appreciate your comments.

    Re: Wireless connection with "WPA2-PSK [AES]" security cannot be established anymore

    What is your kernel version? Check with -
    Code:
    uname -mr
    If it is 3.8 or above, try using the native "brcmsmac" driver instead of the sta driver that you have currently installed. It would also work on lower kernels, but probably not as good as the versions included in kernel 3.8 or higher.

    To purge the current sta driver (so that the native one can load on next boot) -
    Code:
    sudo apt-get purge bcmwl-kernel-source
    Then reboot and check -
    Code:
    lsmod | grep brcm
    Do you see brcmsmac in the output? If yes, can you connect now?

    If not, please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

    While posting the outputs, please use 'Code' tags. It preserves the output's formatting and makes the post cleaner, compact and more readable. To see a quick 'HowTo' with screenshots, please follow the "Using Code Tags" link in my signature.

    Hello Varun,

    I am using 3.2.0-58-generic x86_64
    Do you still recomment to change the driver?

    Thanks,

    Thank you very much indeed.
    Changing the driver to the native one worked just fine.

    Re: Wireless connection with "WPA2-PSK [AES]" security cannot be established anymore

    Glad it worked. If you upgrade the OS or just the kernel later, make sure to NOT install the sta driver again, it often causes troubles with this card and usually the native (current) one works much better than the sta.

    Note that in a fresh installation, choosing to "Install Updates" during installation also installs the sta driver if the system is connected to internet while installing. So you should disable "Install Updates" and "Third Party software" options during a fresh install. You can do them selectively later once the system is installed.

    Enjoy Ubuntu !

    Unfortunately it worked only the first time. After going to sleep mode and back, it couldn't make the connection. Restarting the machine didn't help. I had no change in any of network settings.

    Please use 'Code' tags for the outputs as mentioned in my first post (the bottom line).

    Let us see what options you have available regarding the driver and kernel. Please do an update -
    Code:
    sudo apt-get update
    ..then post the outputs of -
    Code:
    apt-cache show bcmwl* | grep Version
    apt-cache show linux-image-3.* | grep Package | sort -V
    apt-cache show linux-generic-lts* | grep Package

    Re: Wireless connection with "WPA2-PSK [AES]" security cannot be established anymore

    Okay, just one more report please, before we proceed to either compiling a backported driver, or installing a whole new kernel. Please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

    This report is to make sure there is no configuration issue that will persist even with the new driver.

    Here I recommend installing the backport modules 3.6 and linux-firmware-nonfree
