Hi, I need help to use my USB D-Link DWL G122 Rev.E - 5.00 and backtrack 4 Final.I think that chipset is rt2870 but i don't sure. I can run the command airmon-ng ra0 and put the card in monitor mode, but then I do not see the creation of the virtual interface card via the command mon0 iwconfig.When then launch the command airodump-ng is not captured any packets.
Can someone help me with some help?.Maybe a driver problem? Thanks.

Are you sure that your virtual device is called mon0?
