Linux WiFi driver

The Madwifi driver works with this adapter

Madwifi has 2 sets of drivers at the time of this writing (2005-12-03) the new and old ones. The new ones didn't work for me, I had to download the old ones. After installing the old ones, on at least my thinkpad X31 on fedora core 4, after installing the driver (from compiling the source, i.e. make/make install) you need to edit /etc/sysconfig/networking/devices/ifcfg-ath0 and delete the "rate" entry.
