    Exclamation Need Help w/Linksys AE1000 Wireless Adapter on BT5R1, New at BT/ Linux OS

    Introduction:

    Hello, I have a install of 32 bit Backtrack 5 R1 with GNOME as a WM. Recently I bought a Linksys AE1000 which uses the rt2870? drivers (rt3572sta chipset) and I am having some trouble getting it to run properly on Backtrack 5 R1(This adapter however seems to need special configurations with some of the drivers I installed)

    Here's some info directly out of the text document i made and attached:
    #Driver Name 2011_0427_RT3572_Linux_STA_v2.5.0.0.DPO
    #Backtrack 5 R1 Ubuntu
    #Release 10.04 (lucid)
    #Kernel Linux 2.6.39.4
    #GNOME 2.30.2
    #Network Adapter in VMware set to NAT
    #Windows 7 Home Premium, 64-bit 6.1.7601, Service Pack 1
    #VMware« Player Version 4.0.2 build-591240
    #Downloaded BT5R1 Config- BT5R1-GNOME-VM-32
    #File associated with VM creation- BT5R1-GNOME-VM-32.vmdk

    #Tried Searching:
    #http://www.aircrack-ng.org/doku.php?id=aircrack-ng
    #Ubuntu Forums
    #Backtrack Forums (unsolved for me)
    #Backtrack Wiki- compat-wireless and rt2800 Installation Guide (also How-To's)

    I am trying to pentest my WEP secured network.
    I have arrived to the point where I can see my interface (ra0) when inputted: airmon-ng. Yet, when I enable monitoring mode, it says monitoring enabled (sometimes giving a dhclient error) and the interface dissapears.
    When I start airodump-ng ra0, it gives me the menu and items, but no values. This doesn't seem right, because most of the time I can detect the networks using iwlist scan, and when that happens, its usually a monitoring error.
    Before I do all this, I input sudo ifconfig ra0 up (or just ifconfig ra0 up, don't know if there is a difference) so I can get an interface to work with. I have downloaded Ralink's drivers for the results I got on lsusb, and compiled them correctly, with the changes. (I'm assuming)


    Details:

    Here is the output of some basic commands, and everything is in step-by-step order with some hints along the way. (You will find literally everything in the attachment but here is some previews if you cant/don't want to dl):
    iwconfig

    I have found similar issues on all the forums i listed above and more, yet none to be solved.
    I appreciate any help I can get, for I have been on this topic for days straight.
    Thanks for viewing,
    DK

    P.S. Let me know if you need anymore info in order to find a solution.

    Edit: I have got airodump-ng to work with this card, but it stopped working after 7 minutes of recieving data. (I think i know how to fix this- somebody else just made a post about it). The problem is, after it stopped working, I couldn't get it to start working again (I wasn't trying to get it up, was just fiddling around). So now I at least know it can run in monitor. Also, airmon-ng identifies my drivers as 2500 and chipset as 2560 PCI? My adapter im trying to use is USB. (i thought drivers were 2870)???
