Linux WiFi driver
A opensource Linux 'airo' driver is available, and included in recent 2.6 kernels.
There is a sourceforge project page for this driver, but it seems unmaintained.
One of the developers has his own project page here, but there have not been any updates since September 2004.
In addition there is a slightly dated driver available from Cisco after jumping through a bunch of hoops, such as providing Cisco with your personal information.
The current Cisco driver version is 2.1 and only supports select Linux 2.4 kernels.
Known problems
Certain (more recent) firmware might not work with the airo driver. Evidently there is a Windows tool where you can modify the firmware, but if you've already nuked your win32 partition like I have, you'll be in a pickle. For Linux, you want older firmeware version 5b00.08 5.00.03, which is available with version 3.4.9 of the Cisco Windows drivers.
There also have been reports that the Window driver auto-magically updates the firmware, so if you dual boot between operating systems one day your Wireless under the Linux kernel may stop working. I haven't had that happen to me, but be careful about Windows Update or Microsoft Update. Never update the Cisco software in Windows—it also updates the firmware silently.
Get firmware information from /proc/driver/aironet/eth1/Status (airo driver) or /proc/driver/mpi350/Status (mpi350 driver).
