Linux WiFi driver

There's now (04.04.07) added experimental support for the AR5008 chipset to a new branch in MadWifi. I have compiled this driver successfully, but it's still at an experimental stage, so no promises are given. Howto

There is an old ticket for this card at madwifi, #1001.

There is an new ticket for this card at madwifi-branch, #1243.

To install this driver, just checkout the branch madwifi-hal-0.9.30.13.

mkdir /tmp/madwifi
cd /tmp/madwifi
svn checkout http://svn.madwifi.org/branches/madwifi-hal-0.9.30.13/
cd madwifi-hal-0.9.30.13/
make
make install
*choose [r]
reboot

News fron the madwifi-branch:

*  milestone changed from version 0.9.x - progressive release candidate phase to version 0.9.4.
FYI: the madwifi-hal-0.9.30.13 branch has been merged to trunk 
(and the branch has been removed). If you don't want to wait until the next release (v0.9.4), 
you could go with a snapshot or checkout from trunk - just make sure that your code is >= r2360.

Until the madwifi driver stabilizes you might want to get the Windows driver from Lenovo's support site and use a recent version of ndiswrapper (>= 1.29). I've compiled a Howto for this card.

Hardware switch

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