== 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 (beta at the moment, use [[wpa_supplicant]] for WPA-functionality), Monitor/RFMon is supported as of 1.0.6 and firmware 2.3!

Current Version: 1.0.8

Firmware Version: 2.4

Generally works well, but some users experience problems (especially with firmware restarts and with WPA functionality with <tt>wpa_supplicant</tt>); see the discussion page for examples.

{{NOTE|For kernels 2.6.13 and newer, the ipw2200 release candidates require an updated IEEE 802.11 subsystem, which can be downloaded from the [http://ieee80211.sourceforge.net/ ieee80211 project page].}}

=== Power Management ===
To enable power management, issue: 
{{cmdroot|iwpriv wlan0 set_power 7}} 
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: 
{{cmdroot|echo 1 > /sys/bus/pci/drivers/ipw2200/*/rf_kill}} 
To enable the radio, issue: 
{{cmdroot|echo 0 > /sys/bus/pci/drivers/ipw2200/*/rf_kill}} 
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.

Meta:

What is the openGL performance like on this card? Could I play UT2004 and run the OpenGL screensaver hacks at a reasonable speed. In comparison To say a Radeon 9000/9200 card?

It was a pain to get it working under xorg, and once it was running, acceleration required it to be set to 16bit, at 1024x768x16 (a X41) the default glxgears shows ~1300fps, external monitor did not get acceleration (~600fps). And the ogl rendering seams to be buggy with missing textures here and there. I don't know how this translates to UT2004 performance , but you can probably run some opengl screensavers with no problem.
Hopefully xorg 6.9 and 7.0 will provide proper support. --[[User:Meta|Meta]] 23:01, 29 Nov 2005 (CET)
