One thought on “Sony Vaio VPCZ11 with Kubuntu Oneric

  1. WIFI doesn’t work as it should anymore, it’s incredibly slow!

    This worked for me:

    sudo ifconfig wlan0 down
    sudo rmmod -f iwlagn
    sudo modprobe iwlagn swcrypto=1
    sudo ifconfig wlan0 up

    It disabled hardware encryption of the WIFI chip, which is broken in the current driver. To make these changes static just run the following command:

    sudo sh -c ‘echo “options iwlagn swcrypto=1” > /etc/modprobe.d/iwlagn.conf’
