    Default Cannot enable wireless adapter

    HI guys,

    I'm using Backtrack 4 R1, boot from CD on my laptop with wireless card Atheros AR5009. This morning when I tried, everything worked properly.
    But this afternoon, I can't enable the wifi adapter!!!

    When i wrote: airmon-ng
    i have :
    interface chipset driver
    wlan0 atheros ath9k - [phy0]

    after
    When i write on shell konsole : airmon-ng start wlan0
    i have :
    interface chipset driver
    wlan0 atheros ath9k - [phy0] ioctl(siocsifflags) failed: unknow error 132
    (monitor mode enabled on mon0)

    And the wifi indicator on the laptop didn't turn on.

    Can somebody hv the same problem? Please tell me how to solve this. Many thanks.

    If you just upgraded your kernel using apt-get upgrade, then try this link:

    Are you trying to enable monitoring mode, or simply just enable your wifi so that you can go online?

    You might want to start networking before doing anything.

    hi ferrels, I just downloaded and burn BT4 R1 to the DVD and used, no other upgrade or anything.

    @grindcore: I'm trying to enable monitor mode but firstly it's unable to turn the wifi on. There's no wifi switch on my laptop. If u turn it on successfully (like I did on the first time), the wifi indicator on laptop's body will be blue instead of red (as for invisible mode)
