(From  {{T61}} Hardware maintenance Manual)

{{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}}

{{NOTE| Part numbers above will not work with ThinkPad models earlier than the 61 (T61, X61) series, even if the ThinkPad supports Mini-PCI Express.  A 42T0865 card was tested in a T60, and resulted in an 1802 POST error.}}

== Hardware switch ==

Some ThinkPads have a hardware switch that must be in the '''on''' position for the radio to work, regardless of driver state:

* [[Iwl4965]]
* Success with ndiswrapper (on dell 640m) [http://ubuntuforums.org/showthread.php?p=2690284]

== ThinkPads this card may be found in ==
* {{T61}}, {{T61p}}, {{R61}}, {{X61}}, {{X61s}}, {{X61_Tablet}}

== Flaws ==
* lacks promiscuous mode sniffing capability, good signal strength meter (see notes "sharing Experience" at the bottom of link below).[[Talk:Intel_PRO/Wireless_4965AGN_Mini-PCI_Express_Adapter]]

* [http://www.thinkwiki.org/wiki/Iwl4965 iwl4965]/iwlagn driver can cause kernel panics in some cases on Ubuntu Hardy 8.04 and Intrepid 8.10 (and possibly others).  See [https://wiki.ubuntu.com/IntrepidReleaseNotes#System%20lock-ups%20with%20Intel%204965%20wireless Intrepid release note] and [https://bugs.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.27/+bug/276990 Launchpad entry].  Some sources say this is fixed in linux-backports-modules-intrepid-generic, while others still report kernel panics with the backported module.
