{{NOTE| Only the IBM Parts will work, any other parts will give an 1802 error on Post because the sub-vendor PCI ID is different, see [[Problem with unauthorized MiniPCI network card]] for more details}}<br />

=== Linux WiFi driver ===<br />
The most recent revision of the Intel Centrino platform does utilize a new generation of wireless networking device, connected to the system via '''PCI-E''', and not PCI (like the [[ipw2200]]-line used to do). Therefore, a new driver is to be used. A sourceforge-project aimed to support the new cards is available on [http://ipw3945.sourceforge.net/ http://ipw3945.sourceforge.net/]. However, as of today, the project's code (which is not in production stable condition) depends on a '''binary-only, proprietary''' user-space-daemon communicating to the driver via sysfs. It is '''not possible''' to operate this device with Free Software exclusively at the moment. The license-terms the daemon is released under prohibit reverse-engineering of the communication-protocol; this will hopefully not hold developers from countries other than the US, where clauses like this one are not enforceable, from re-implementing a free variant of some sort.<br />
==== External Discussion ====<br />
This issue already sparked discussions on the [http://lkml.org/ Linux Kernel Mailing List], accessible via [http://lkml.org/lkml/2006/2/24/266 http://lkml.org/lkml/2006/2/24/266].<br />
<br />
==== Current State ====<br />
The [[ipw2200]]-drivers in kernel 2.6.15 (and possibly later) do '''not''' work with this adapter. There is '''no mainline-kernel support''' at the moment, and without a change in the license of the required user-space-daemon, or mechanics of the code itself, '''probably''' will never be any.<br />

<div>== Internal Ethernet controller ==<br />
<br />
A variety of [[Ethernet]] controllers is integrated into almost all models starting with the introduction of the A, T and X series.<br />
<br />
The Ethernet controller is located on either a MiniPCI card, Communications Daughter Card (CDC), or integrated on the systemboard.<br />

Driver: [[e100]] (The 'e100' driver is the suggested driver, but '[[eepro100]]' should also work.)<br />
<br />
=== Intel Gigabit (10/100/1000) ===<br />
Chipset: Intel PRO/1000 MT Mobile Ethernet<br /><br />
Driver: [[e1000]]<br />
<br />
This chip is integrated into select systemboards of the following machines:<br><br />
'''Intel 82540EP'''<br />
* {{R50}}, {{R50p}}, {{R51}}<br />
* {{T40}}, {{T40p}}, {{T41}}, {{T41p}}, {{T42}}, {{T42p}}<br />
