The previous version of ipw2200 can't be compiled with the linux headers 2.6.20-16-generic (used by Ubuntu 7.04) so here is the way to get the rtap0 interface working.

• ieee80211-1.2.17.

Make sure that you have this library else ipw2200-1.2.1 drivers won't compile

wget http://superb-west.dl.sourceforge.net/sourceforge/ieee80211/ieee80211-1.2.17.tar.gz
tar zxvf ieee80211-1.2.17.tar.gz
cd ieee80211-1.2.17
sudo make
sudo make install

• Get the patch and the driver.

drivers patch link

wget http://superb-west.dl.sourceforge.net/sourceforge/ipw2200/ipw2200-1.2.1.tgz

• Patch the driver.

tar zxvf ipw2200-1.2.1.tgz
tar zxvf ipw2200-1.2.1-inject_patch.tar.gz
patch ipw2200-1.2.1/ipw2200.c ipw2200-1.2.1-inject.patch
patch ipw2200-1.2.1/Makefile ipw2200-1.2.1-inject_Makefile.patch
cd ipw2200-1.2.1
sudo ./remove-old
sudo make
sudo make install

• Turn on the module.

sudo rmmod ipw2200
sudo modprobe ipw2200 rtap_iface=1

At this stage if you see that your module can be loaded, you can load it at boot with the option “rtap_iface=1”. Just edit the file “/etc/modprobe.d/options” and add the line “options ipw2200 rtap_iface=1”

• Now you should be able to bring up the rtap0 interface and listen with airodump-ng.

sudo ifconfig eth1 up
sudo ifconfig rtap0 up
sudo airodump-ng rtap0 -c 11 --bssid 00:0f:e2:xx:xx:xx --ivs -w dump

See this thread.

For the code see:

• http://precompiled.de/~jamx/

If you want to channel hop, use the ethX interface where X is the interface that got created while loading the driver.

You get it by specifying rtap_iface=1 while loading the driver or by setting the appropriate value in /sys.

The rtapX interface allows packet capture while you are in managed mode.

Try adding the channel settings to the modprobe:

 modprobe ipw2200 rtap_iface=1 channel=X

Where X is the AP channel.

The ipw2200 driver does not support the transmission of management frames such as deauthentication.
