hi my hardware:
D-link dwl 520+ with texas instrument ACX100 chipset! i bought this cause this one is the most available and i did checked the driver capable list on aircrack-ng.org website but the drivers out there and the patch did nothing i mean in backtrack 4 it is not working at all (at least i can't install it) the only distru detects it automaticly is ubuntu and i did cracked wep (my own AP which was d-link dsl-2640) with listining to packeges (read linux newbie tut at aircrack-ng website) i'm not sure it can inject the packages cause in packet injecting test i got almost nothing anyway if someone knows how to work with this just let me know !!
