=== IBM Partnumbers ===
IBM Option PN (US):

=== Linux WiFi driver ===

There's no support by [[Madwifi]] yet (as of March 01, 2007). This card is tracked by [http://madwifi.org/ticket/1001 madwifi ticket #1001].

In the meantime,

get the driver from http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-66449 and use ndiswrapper

=== Hardware switch ===

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

(Note: This may not always be the case. On at least one T60, model 2007-62U with Atheros AR5212, running Ubuntu Edgy with the MadWifi driver, the wireless switch has no effect. Wireless operates with the switch in either position. But there's an [http://article.gmane.org/gmane.linux.acpi.ibm-acpi.devel/137 experimental patch] which adds support of the switch to [[ibm-acpi]].)

This is a physical switch that lies on the lower side of front edge of the Thinkpad toward the left side. You will see a green bar on the left side of this switch if it is turned on. If you switch from off to on and this is the problem with the wireless card the service will be enabled.
