TROUBLE : ndiswrapper/monitor/broadcom/airodump/aircrack : HELP PLEASE
Ok I am trying to get all these backtrack tools to work on my computer. Unfortunately I have a broadcom wifi adapter, but thats not the issue. I am able to get the adapter working with ndiswrapper and I am able to see networks through the wifi manager. Until yesterday I didnt know I needed to be in monitor mode to get things to work. So I did some research and found out that monitor mode is not supported through monitor mode. So I did some more searching and found a patch to ndiswrapper called bcmmon that enables it to go into monitor mode. So I followed these steps and as you can see I got everything up and running and put wlan0 into monitor mode but when I try to run airodump-ng and aircrack-ng I get two seperate errors. One saying that ndiswrapper does not support monitor mode and the other that says it cannot see any networks. It shows that I put it into monitor mode and I can view the available wireless networks in the wifi manager. Is there anyone who has dealt with these issues or someone who knows what to do? Below is exactly what I did and what the outputs are. Thanks

Ndiswrapper works only in managed mode.you can't use them for monitor mode as error indicating.second thing the command syntax of aircrack-ng is wrong.read it properly as it needs a input capture file to process.upgrade the kernel to latest one 2.26+ to support those broadcom cards.
