Atheros mini-PCIe WiFi Adapter

IBM Partnumbers

IBM Option PN (US): 40Y7026

Linux WiFi driver

Use the Madwifi driver. This driver has support for Atheros rev 0x0024 support since svn revision 2360.

OR (not recommended)

get the driver from 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:

(ThinkPad R60 radio switch in the ON position)

(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.)

T60 WiFi LED

Problem: The WiFi LED on the T60 isn't enabled by default on bootup.

Solution: As root edit /etc/rc.local by adding the following command at the bottom:

echo -n 1 > /proc/sys/dev/wifi0/ledpin;

Save your changes, afterwards on every boot up the WiFi LED will be enabled.

Note:This has been verified on a T60 1953-D7U running Fedora 7 Linux, however this should work on most Laptop-OS configurations.
