    Default Centrino Advanced-N 6230, broadcast traffic only, sometimes

    With BT5r3

    Noticed I was only getting broadcast traffic sniffing.

    Yesterday I updated to the latest firmware from Intel, not sure if that changed anything.

    If I do

    # iwconfig wlan0 mode monitor channel 149
    # airodump-ng wlan0 -c 149 -w test


    , with an 802.11a client, everything works.

    If I do

    # iwconfig wlan0 mode monitor channel 6
    # airodump-ng wlan0 -c 6 -w test


    , with an 802.11n client on 2.4 GHz, I only see broadcasts.

    Seems pretty repeatable.

    Tried using airmon-ng, the mon0 interface it creates, etc., no change.

    Also, the monitor mode checkbox in Wireshark is grayed out, but that may be a different problem, since iwconfig does say that the interfaces are in monitor mode.

    Seems that 802.11n was not working--creating /etc/modprobe.d/iwlwifi.conf with

    options iwlwifi 11n_disable=0

    makes it work.

    Got this from an Ubuntu support forum (odd that it isn't the default...unless you are trying to save power (but I was plugged in...))
