    Apparently it's in the non-working hardware: http://www.backtrack-linux.org/forum...ad.php?t=54872

    You may have luck searching on the aircrack forums too.

    There is a driver to your chipset in realtek web page, although it is not known if driver support native monitor mode and injection.

    As sickness informed you, you might want to take a look at the aircrack-ng site and see if there is any "patch" for the driver and for kernel >=3.0.x.

    I'll give you an advice: If you want something that work "out of the box" use usb devices. Search wiki and forums for compatibility.

    Luck.

    What is your setup in vmware...
    If you have your usb wifi installed on your host os the virtual machine might be seeing it as a wired connection. Do you connect it before you load the vm or after?
    You may want to disable uninstall the drivers in the host.

    Were you able to fix problem?..Please post. Do not leave a post open, just write {SOLVED}. Many people is trying to help without knowing if you already solved your issue.

    I can help but again, just post the status of your issue.

    Do not make other people spend their time in something SOLVED, if applicable.

    He may or may not have fixed the issue, I however have not. I am having the same problem, a RTL8191SU chipset. Some had a similar issue with the RTL8192SU chipset, which actually uses the same module, r8712u. However, despite following the instructions found here the same does not seem to work for the RTL8191SU chipset.

    I should also mention, while Realtek does have a driver on their website for Unix/Linux, it seems to be compatible up to the 3.0.2 Linux kernel, when attempting a make command on the driver, it errors out, I am not good enough with scripting to figure out why, yet.
