Linux WiFi driver
As of march 23, the madwifi driver does work (tested the nightly build) If you still got problems check madwifi ticket #1001. Alternativly you could 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 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.
