well i bought W-lan stick now
and now the problem is , that backtrack 4 does not detect any usb device.
No usb stick and no W-lan stick, is there a command or smt to activate usb ?

[Sethioz]

no there is no command, but there are drivers. i suggest installing uBuntu instead. your laptop was a big mess, i suggest format it and put xp + ubuntu on it as dual boot, if you want to make it a powerful cracking and hacking tool.
i assume you are testing it on laptop, i remember that backtrack4 didn't even detect your internal adapter on some reason.
anyways try if USB stick works fine in windows (any windows). if so, then you need drivers.
ubuntu should install them manually.

also give more info, what usb it is ? it might be some compatibility problem, check http://www.aircrack-ng.org and search for the list.
registering and asking a question on their forum is quite pointless, they are full of themselves and won't really help, they just say "google" or "read wiki" .. thats dumb.
however its not so hard to find the compatibility list on their site. its a hassle, i know, but this is how cracking and hacking is.

1. find out what chipset your USB card has (manufacturer doesn't matter, just the chipset)
2. go to http://www.aircrack-ng.org and find out if your chipset is supported (it might be supported on windows, but i doubt).
3. either get right drivers from http://www.aircrack-ng.org or install ubuntu and see if it install them.
4. in ubuntu get "aircrack-ng" suite, using synaptic packet manager.

YEah , my USB stick works fine in any windows and my W-lan stick 2
So the problem is in Bt4 , so ill get ubuntu now and follow ur sugesstions :)

Ok i got Ubuntu now , and installed nicey
Now i neeed to get my W-lan stick running there, what i need to do for that is fist downloading all the Ubuntu updates
what i CANT do because the partition of Ubuntu wich it created itself is to small , so i downloaded Gparted Partition manager and try to resize the partition...
I also figured out my chipset of my W-lan stick, Its " Atheros "

[Sethioz]

atheros is most common, so it should work fine, but this isn't linux discussion, next time use manual setup or "side by side" option.

EDIT:
you do not need ubuntu updates (unless its some old shit, but im sure you downloaded new one. 9.10 is newest atm).
im not sure about below 9.04, but my first ubunut was 9.04 and it worked just fine without any additional drivers.
all you need to do is just download "aircrack-ng". you can do that via synaptic update manager or console ("apt-get install aircrack-ng" should work)

I did that but it still does not detect my W-lan stick.
Theres a little light on my w-lan stick wich is not glowing either

so wht did i do wrong ?

NOTE:Its not the USB device, it detects my USB sticke fine now !

I was looking for an tutorial on how to get my fucking Wlan stick working but still no succses :@

I found this : http://ubuntuforums.org/showthread.php?t=663897
And followed this tutorial like the other guy did : https://help.ubuntu.com/community/Wi..._(ndiswrapper)

And everything worked like the tutorial explained but without any result !!
It still does not detect my friggin TL-WN620G W-lan stick ...
BTW i've got the Ubuntu 9.04 Jaunty Jackalope
PLEASE HELP ME !

it is totally offtopic, there's a linux topic somehwere, if you can't find it, make a new one with as detailed title as possible.

i decided go wireless fishing and i tripped over tought one. it uses SKA (shared key authentication), but it should matter.
its WEP ofc, problem is that nothing seem to be working properly. i keep getting errors using -4 and -5 options in aireplay.
i tried different MAC addresses and still nothing. some stations temporarly ban your MAC if you keep flooding them, so you must run new fake auth using new faked MAC and then change MAC for other commands too, but this one is even toughter than that.

what seem to be working best, is that there is one connected client and i stole its MAC and using that, so no authentication is needed at all. this reduces traffic between me and AP. it might be bad signal and it might be bad router.
anyway, if you have this issue, try stealing MAC from connected clients, it might work better than fake auth.

however if connected client sends enough data, then there is no need to do anything else but just wait and get enough data packets and crack it. in my case connected client is not sending enough data, like 5000 packets in hour, so i have to wait 5 hours to get it cracked without any interaction from my side.

i've done it so many times, yet i find new tricks and tools.
for example i have one tought station that doesn't even accept fake authentications. seems like it has MAC filtering on, however what i did, is i changed my MAC to same as AP itself and then it accepted the fake authentications.
just a note what to do if it won't accept fake auths.
however other problem is that it won't send any data packets at all. it's odd tho. authentication is OPEN, it should accept all, must be MAC filtering only. anyway it works if you use AP's own MAC.
