    Re: Atheros AR9285/Ubuntu 11.04/Lenovo B575 (Wireless Disabled?)

    Scratch that. I don't think we're finished quite yet... After a restart I am now unable to connect to any wireless connections be it secured or unsecured. Now when I try to connect to a network it tries and tries and eventually gives up and disconnects.

    iwconfig output while attempting to connect to WPA2 AES network:

    Code:
    mark@ubuntu:~$ iwconfig wlan0
    wlan0     IEEE 802.11bgn  ESSID:"teamRAMROD"

    ifconfig right after that:

    Re: Atheros AR9285/Ubuntu 11.04/Lenovo B575 (Wireless Disabled?)

    After resetting my modem and router it is working fine now. I didn't think to do that last night since I wasn't able to connect to other networks either but after I booted into Windows this morning and still couldn't connect a light bulb lit up. All seems to be in order now. Thanks again for all your help! I will mark this thread as solved.

    Thanks to all who contributed above. I also just installed 11.04 onto a Lenovo B575 and experienced the same problem of wireless not working.

    I now run the following script (from info above) after I logon to get wireless working:

    wireless.sh contents:
    #!/bin/bash
    sudo ifconfig wlan0 down
    sudo rmmod -f acer-wmi
    sudo rmmod -f ath9k
    sudo modprobe ath9k nohwcrypt=1
    sudo ifconfig wlan0 up

    I think it may also be necessary for the kernel to be updated to at least 2.6.38-11-generic. The current LiveCD has 2.6.38-8-generic.

    I probably won't add this to my config files. Hopefully a later update solve this without any additional action by the user.
