REf Linksys card...

This may or may not help.  I can use my Linksys card in Familiar, more
or less (frame and multicast errors but I can still network), using
their OTB (out of the box) config.  I am still having issues getting
Intimate to boot w/o resetting the linuxargs each time so I don't
remember if there were issues with that, however, in RH and Mandrake
systems I need to download and install the linux-wlan-ng drivers/stuff
(http://www.linux-wlan.com/linux-wlan/)to get it working (more or less,
networks fine, shows up in the ifconfig fine, but doesn't show up in the
iwconfig and don't know if it should).  You might try that if you are
not getting it to work otherwise, I installed that and it was working
right away (don't forget to tweek the config files listed in the
readme).
If that doesn't work there was something in the Familiar email listings
(might have been six months ago) about a tweek that was used before to
make Linksys wireless cards work and that might have some clues.  I'm so
lazy that the distro version incorporated it before I got around to
figuring it out so I'm no help there.
Good Luck.
