== Intel PRO/Wireless 2200/2915 Driver for WiFi ==
Linux driver for the 802.11bg and 802.11abg NICs - miniPCI cards - found in Centrino laptops. This driver only works on 2.6.x kernels (2.6.4 or newer).

The following adapters sold by IBM use these chips:
* [[Intel PRO/Wireless 2200BG Mini-PCI Adapter]]
* [[Intel PRO/Wireless 2915ABG Mini-PCI Adapter]]

=== Project Homepage / Availability ===
http://ipw2200.sourceforge.net/

=== Packages ===
*{{Fedora}} Packages(1): Fedora Core includes the ipw2200-drivers in FC3 (with updates) and FC4. You still need to grab the firmware from http://rpm.livna.org/
*{{Fedora}} Packages(2): http://www.atrpms.net/name/ipw2200/ 
*{{Mandrake}} 10.1: The ipw2200 driver modules are included in the stock kernel package.
*{{Gentoo}}: The driver is in the portage tree: emerge net-wireless/ipw2200 and net-wireless/ipw2200-firmware
*{{Debian}} Packages: http://packages.debian.org/ipw2200-source

=== Status ===
In development, usable, WEP 128bit encryption works, WPA does also work with drivers >= 1.0.2 and [[wpa_supplicant]], monitor/rfmon is supported as with version >= 1.0.6. Generally works well, but some users experience problems (especially with firmware restarts, with WPA functionality using [[wpa_supplicant]], and in the absense <tt>hwcrypto=0</tt> parameter); see the discussion page for examples.

Latest versions:
* ipw2200 driver: 1.0.8
* firmware: 2.4
* ieee80211 stack: 1.1.6

Mainline kernel 2.6.15 contains the above ipw2200 and ieee80211 versions, so only the [http://ipw2200.sourceforge.net/firmware.php firmware] needs to be added. For earlier kernels, you need to separately install the [http://ipw2200.sourceforge.net/downloads.php ipw2200] module and, for kernels 2.6.13 and 2.6.14, also the [http://ieee80211.sourceforge.net/downloads.php ieee80211] stack.


=== Installation from sourcecode ===

Download the latest [http://ieee80211.sourceforge.net/downloads.php ieee80211] stack and install it:

 # tar xzvf ieee80211-1.1.6.tgz
 # cd ieee80211-1.1.6
 # make
 # make install

Download the latest [http://ipw2200.sourceforge.net/downloads.php ipw2200] module and install it:

 # tar xzvf ipw2200-1.0.8.tgz
 # cd ipw2200-1.0.8
 # make
 # make install

Download the matching [http://ipw2200.sourceforge.net/firmware.php firmware] and install it:

 # tar xzvf ipw2200-fw-2.4.tgz -C /lib/firmware

=== Installation on Debian ===

Install ieee80211-source

 # apt-get install ieee80211-source
 # module-assistant -t build ieee80211-source

Install ipw2200-source

 # apt-get install ipw2200-source
 # module-assistant -t build ipw2200-source

There is a bug in the debian package (last checked: Dec 17th 2005) that prevents from linking to ieee80211 modules using module-assistant. In case it is not fixed in your version, fall back to the regular source installation procedure described above.

The firmware is not distributed with debian due to licensing reasons, download the matching [http://ipw2200.sourceforge.net/firmware.php firmware] and install it:

 # tar xzvf ipw2200-fw-2.4.tgz -C /lib/hotplug/firmware

see /etc/hotplug/firmware.agent for details on configured firmware locations

=== Test ===

 # modprobe ipw2200
 # iwconfig

dmesg output might look similar to this:

 # ieee80211: 802.11 data/management/control stack, 1.1.6
 # ieee80211: Copyright (C) 2004-2005 Intel Corporation <jketreno@linux.intel.com>
 # ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.8
 # ipw2200: Copyright(c) 2003-2005 Intel Corporation
 # ipw2200: Detected Intel PRO/Wireless 2915ABG Network Connection

=== Power Management ===
To enable power management, issue:<br />
{{cmdroot|iwpriv wlan0 set_power 7}}<br />
where <tt>wlan0</tt> is the name if your interface. This will reduce idle power consumption by several Watts compared to no power management.

To disable the radio (and further reduce power consumption) when the card is not in used, issue:<br />
{{cmdroot|echo 1 > /sys/bus/pci/drivers/ipw2200/*/rf_kill}}<br />
To enable the radio, issue:<br />
{{cmdroot|echo 0 > /sys/bus/pci/drivers/ipw2200/*/rf_kill}}<br />
To make the radio off by default after boot, add 
 options ipw2200 disable=1
to your {{path|/etc/modprobe.conf}} or equivalent.

See {{path|README.ipw2200}} in the <tt>ipw2200</tt> package for details and other options.

=== Additional Comments ===
Your kernel may include an old version of the ipw2200 driver. It is recommended to use the latest version.

Make sure you also install the firmware version needed by the driver version you use. You can find the firmware [http://ipw2200.sourceforge.net/firmware.php here]. To install it, decompress the <tt>.tgz</tt> file into <tt>/lib/firmware</tt>.

The driver doesn't appear to support MII interface, so any tools like automatic network configuration managers ( whereami ) that rely on mii-tool do not work.
