IEEE Standards: 802.11a, 802.11b, 802.11g (802.11n Some models Only) PCI ID: 8086:4230 PCI ID: 8086:4229 (not actually seen on Thinkpad, yet) PCI ID: 8086:4233 (not actually seen on Thinkpad, yet) PCI ID: 8086:422D (not actually seen on Thinkpad, yet)

Lenovo Partnumbers

42T0865, 42T0867, 42T0869, 42T0871, 42T0905 : Intel PRO/Wireless 4965AGN (11n enabled)

(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:

Support

Procedures for using this card under Linux using Intel wireless driver

• http://forums.fedoraforum.org/forum/showthread.php?t=159550
• Installing Debian Lenny on a ThinkPad T61#WiFi: Intel 4965AGN

ThinkPads this card may be found in

• T61, T61p, R61, X61, X61s, X61 Tablet, X300

Flaws

• lacks promiscuous mode sniffing capability (however, works OK in Linux (2.6.27 onward) with aircrack), good signal strength meter (see notes "sharing Experience" at the bottom of link below).Talk:Intel_PRO/Wireless_4965AGN_Mini-PCI_Express_Adapter

• Iwl4965/iwlagn driver can cause kernel panics in some cases on Ubuntu Hardy 8.04 and Intrepid 8.10 (and possibly others). See Intrepid release note and Launchpad entry. Some sources say this is fixed in linux-backports-modules-intrepid-generic, while others still report kernel panics with the backported module.

• [iwl4965] Wireless enabled/activity LED does not light under ubuntu hardy (8.04.1). There are reports that this is fixed in intrepid (8.10). Front panel switch ... at front under the keyboard ... does disable both wifi and bluetooth. The bluetooth LED cycles on/off with the switch appropriately. Only 802.11 wifi LED is problematic.
