    Default Backtrack5 freezing after connect Wireless

    Hello everyone, I have a dual boot (with Win7) install of backtrack 5 r1 GNOME 32bits (kernel 2.6.39.4) on my notebook.
    The system is working fine, and i didnt have any problems during the installation, but when I connect to the internet using a wireless connection, in the begin everything looks fine, I can access some websites, but some seconds/minutes later my Backtrack 5 freezes completely and I have to reboot the notebook.
    OBS: Using a wired connection, I didnt have any problem

    iwconfig
    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.

    I searched alot about that, and I didnt find anything that could fix my problem until now.
    Thanks for the attention.

    Some additional info:
    -When my network cable is connected to notebook, I can connect using wireless and got no problems, but if I remove the cable, my Backtrack freezes again. Could it be some conflict issue with drivers?
    -Sometimes I had the error message from wicd: "Could not connect with wicd D-Bus interface", so I tried this to fix the problem:
    Code:
    dpkg-reconfigure wicd
    update-rc.d wicd defaults
    And my wireless connection worked fine, but after the first time I rebooted my computer, the freezes started again.
    -On Windows 7 my wifi card is named Atheros AR9825 and on Backtrack Atheros AR9287. Could it mean something?

    Hope someone can help me, cause im getting sick of this problem...
    Thanks.
