    11.04 wireless issue AR9287/AR5B97

    Im dualbooting my new acer aspire 1830T.

    with windows 7 the atheros wireless card works great.

    with the latest ubuntu it doesnt work at all.

    Windows reports it as an Atheros AR5B97 however doing a lscpi in ubuntu shows it as an AR9287.

    Not too sure what i should be doing to get this up and running in ubuntu, any help would be much appreciated.

    Thanks.

    Have you tried installing wireless-compat?

    It's most likely a driver issue. Have you tried plugging into you router to download all the necessary drivers?

    Hy!

    I am not sure that this will help you if you have no connection at all, but definitely works when you have some unstable connection.

    Code:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    Then reboot.

    I have Acer Aspire 5750G, the wireless is AR5B97 in windows and AR9287 in Ubuntu 11.04.

    In Ubuntu I can see my home network and attempt to connect but after few minutes the authentication dialogue reappears. The same happens with Fedora 15 (live CD) but Puppy Linux 0.5.2 connects (also live CD).

    I am now on Windows 7 looking for a solution, I looked up "modprobe.d" and found this: http://linux.die.net/man/5/modprobe.d

    did you mean to write:
    Code:
    sudo modprobe -r acer-wmi
    should I reboot after this command or not?

    thanks a lot.

    I tried the following:

    Code:
    ~$ sudo modprobe -lv acer*
    kernel/drivers/platform/x86/acer-wmi.ko
    kernel/drivers/platform/x86/acerhdf.ko
    
    ~$ sudo modprobe -rv acer-wmi
    rmmod /lib/modules/2.6.38-8-generic/kernel/drivers/input/sparse-keymap.ko
    
    ~$ sudo modprobe -rv acer-wmi
    
    ~$ sudo modprobe -lv acer*
    kernel/drivers/platform/x86/acer-wmi.ko
    kernel/drivers/platform/x86/acerhdf.ko
    still I couldn't connect (even after a reboot).

    I tried adding a ath9k.conf with the line in ziad.ra's post but that made the whole wireless network disappear (after a reboot).

    Anyone has an idea what to do?

    I don't think that is the problem because Puppy Linux (0.5.2) reports it as AR9287 but connects with the network without any problems!

    If anyone has an idea about this one please help, thanks.
