well, welcome to linux. Since it is a pcmcia device lets tests that linux sees the device first. Its been awhile since i've played with a pcmcia device, but it shouldn't be a problem.
as rood open up a terminal and run
if you get
cardmgr: no pcmcia driver in /proc/devices
don't procede as you will need to load the yenta driver.
the manufacturer of that card didn't make any linux drivers, so you'll have to use windows ones =P. go to http://ndiswrapper.sourceforge.net
download it. Then do
tar -zxvf ndiswrapper.tar.gz
make && make install
note that your download will undoubedly be different so change it to match your file. The program should now be installed.
Next you'll need the windows drivers for your card. you'll need 2 files, one ending in .inf and the other .sys. After you get them copied over do
ndiswrapper -i urdriver.inf
ndiswrapper -l #-l = lowercase L
you should see some output indicating driver present, hardware present.
to set your ssid and such read
however, if you are using wpa encryption on your network, you will nee wpa_supplicant.
the website is wpa_supplicant
but it seems to be down at the moment.
If you get stuck at any part, you can post here. While you are waiting for a reply it would be a good idea to search the forums for problems like yours.
