    Question Ubuntu 11.10 64-bit Dell laptop wireless problem

    Hi guys,

    I have a Dell Laptop 14z N411z laptop. It comes with Windows 7 64-bit OS .
    Also I installed Ubuntu 11.10 64-bit edition.
    My laptop sees wireless networks bu can't connect to them. It gives wrong password error even if I make the network unsafe.
    When I tried with Ubuntu 11.10 32-bit edition it successfully connects wireless networks.
    Below is the lspci output.

    Hi,

    deactivate the N-mode of the driver:

    echo "options iwlagn 11n_disable=1" | sudo tee /etc/modprobe.d/iwlagn.conf
    and reboot.
