Greetings! Here are two different Debian variants that work quite nicely on an CF-18 and CF-19, as well as older and newer model Toughbooks:http://crunchbang.org/about/http://www.planetwatt.com/pages/downloads
These should find your wireless lan straight-a-way by clicking on the icon at the top of screen next to the battery icon and the speaker icon...The MK1 CF-19 also works quite well on many, many flavours of Linux, especially SoldydX and Mint to name just a few:http://solydxk.com/http://www.linuxmint.com/
There are many more but these four listed above work quite nicely.
welcome to the madness.....
