I'm setting up a network with a client that has a Cisco Systems 350 PCI wireless LAN adapter and is configured using an Aironet utility in Microsoft Windows.
Using Knoppix I was able to join the wireless network with the default router set up and could ping the router, so everything was working fine.

I then tried to set it to monitor mode using iwconfig eth0/wifi0 mode monitor, but it never changed the mode, I could change it to ad-hoc but not monitor mode.
I assume that this card does support monitor mode and doesn't need any patch drivers, if so then what can be the problem?

When I typed iwconfig eth0 mode monitor and pressed enter, the cursor went to a new line with nothing on it, not even the prompt. I tried opening Airsnort, Ethereal etc but they kept crashing. AirSnort gave me a "segmentation error".

I ran Kismet and got the error message "FATAL: pcap reported netlink type 1[EN10MB] on eth0. This problem means you are not in RFMON mode or your drivers are reporting a bad value. Make sure you have the correct drivers and that entering monitor mode succeeded."

Looking in Microsoft Windows device manager I found the following:
Driver - airo.C 0.6
Device - 350 series
Firmware Version - 4.25.30


1. Do I have the right driver or do I need to download some? if so which one's and where from?
2. How else can I set it to monitor mode other than iwconfig wifi0 mode monitor?

I ran a google search and someone said to solve it you need to do this:
#!/bin/sh
cardctl scheme kismet
ifconfig eth0 down
kismet-monitor -i eth0
ifconfig wifi0 up
echo "Mode: r"> /proc/driver/aironet/eth0/config
echo "Mode: y"> /proc/driver/aironet/eth0/config
kismet -1 wifi0

But I'm not sure if I have to edit a file or type it at the shell prompt, I typed it at the shell prompt and it never got past the first line "cardctl scheme kismet".

I looked in /proc/driver/aironet/eth0 but didn't see much except things such as status and the current config with the SSID etc.

Thanks for any help
