====== ipw2200-1.2.1 how to ======

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
<code bach>
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
</code>

  * **Get the patch and the driver.**
[[http://www.box.net/shared/j3qvacbbmb|drivers patch link]]
<code bach>
wget http://superb-west.dl.sourceforge.net/sourceforge/ipw2200/ipw2200-1.2.1.tgz
</code>


  * **Patch the driver.**
<code bach>
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
</code>

  * **Turn on the module.**
<code bach>
sudo rmmod ipw2200
sudo modprobe ipw2200 rtap_iface=1
</code>
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.**
<code bach>
sudo ifconfig eth1 up
sudo ifconfig rtap0 up
sudo airodump-ng rtap0 -c 11 --bssid 00:0f:e2:xx:xx:xx --ivs -w dump
</code>

====== 2.6.24 kernel support ======

See this [[http://forum.aircrack-ng.org/index.php?topic=400.msg18264#msg18264|thread]].

====== Troubleshooting Tips ======
===== Airodump-ng will not channel hop =====

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

===== How do I get the rtapX interface =====

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.

===== "rtap0 is on channel 0, but the AP uses channel X" message =====

Try adding the channel settings to the modprobe:

   modprobe ipw2200 rtap_iface=1 channel=X

Where X is the AP channel.

===== Deauthentication does not work =====

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