    Tell me a little bit of what I'm reading here. I understand it sorta. So the "module" is the device or driver? "Used by" meaning what?

    Thank you again. This is a great learning experience. I don't want to be totally reliant. This was the whole purpose of moving to Linux. lol

    Re: NOOB status: Configure wireless card for Ubuntu 11.10

    An unexplainable fix to most wireless problems (I won't go into details) is being fixed with (for example for me) WICD network manager. You can give it a try,you can install it via the package manager,nothing complicated. The only thing that you have to add manually is the wireless interface in the Preferences,which should be wlan0 (you have to type it) ,tell me how it went,cheers

    ++ Here's an exact screenshot if I got you confused with my explanation http://4.bp.blogspot.com/-FgQHVo9XFI...references.png
    I killed hope,but you buried it....

    Re: NOOB status: Configure wireless card for Ubuntu 11.10

    I barely understood that! lol. But I got it. I downloaded the manager via Synaptic and opened up the wizard. So what does this do anyways? Got any idea? You said it was an odd fix.

    I'll let you know how it affects my network performance and if my wireless is still dropping signal.

    Re: NOOB status: Configure wireless card for Ubuntu 11.10

    Hi, the information you posted shows all the drivers in use on your system, and the driver is loaded for your wireless card there are two things most likely going on by looking at your information, we need to disable N speed and you may have a problem with the kernel telling the wireless to turn on, so we need to check for that as well.

    Everything I have learned is from working on the forum, spending hours and hours of studying and research.

    Please do this for the N speed issue.
    Code:
    gksudo gedit /etc/modprobe.d/iwlagn.conf
    add one line:
    Code:
    options iwlagn 11n_disable=1
    Proofread carefully, save and close gedit. Reboot.

    If it does not come on post:
    Code:
    iwconfig
    rfkill list all
    nm-tool
    Thanks

    These are the results. The speeds are still the same. It started off lower but worked its way up to 54mbps.

    Hi, change your settings to match the screenshots except leave yours to auto connect then reboot.
