    We are going to remove the last parameter we added and add another one.

    Please do:
    Code:
    gksudo gedit /etc/modprobe.d/iwlwifi.conf
    remove wd_disable=1 and add bt_coex_active=N
    save and close gedit and reboot.

    Please post everything that is in that file.
    Thanks

    Can you tell us the kernel version you are using? Run "uname -r" and report back the results.

    My Intel adaptor refused to connect with one recent kernel version, but came back to life in the next one. I'm now on 3.8.0-23-generic, and the card connects with WPA2.
    If you ask for help, please have the courtesy to check for responses and thank the people who helped you.

    Re: Unable to connect to Wi-Fi network after upgrade

    The Kernel its running is 3.8.0-25-generic. I get nervous about go back to older versions of Kernels, forced clean installs in the past.

    That last file change did it Wild Man, I'm now totally unwired. Thanks so much for the help! I'm glad that you where able to find a solution. Sorry for any trouble it may have caused, I'm somewhat computer illerate when comes to the hardware interfacing bits.

    Hi, would you mind posting the wireless script information and the complete contents of the file we have been working on, it will help with our learning experience and make it easier to help people in the future.
    Thanks

    Just as an added data point, I just upgraded from 3.8.0-23 to 3.8.0-25 tonight. My wireless continues to work without incident using Kubuntu's network manager and no additional shell commands.
