Ghost2 - 2006-10-29

I Just started using linux with the Fedora Core 6 distribution. The only way the machine (a 5 y/o sony VAIO Laptop) can connect to the internet is through a Linksys WPC54B PCMCIA card, which, of course, does not work. I looked into it and found that ndiswrapper should help. The only problem is that I can't get it installed. I originally tried following the INSTALL instructions (for 1.28rc2), but couldn't get past the Prerequisites step. I then searched around and found an rpm version of ndiswrapper, but fc6 needs an internet connection to do that. I then find the Fedora specific instructions here: http://ndiswrapper.sourceforge.net/mediawiki/index.php/Fedora, but the SymLink step (ln -s /usr/src/kernels/<kernel-version> /lib/modules/<kernel-version>/build) doesn't work (no "/lib/modules/2.6.18-1.2798.fc6/build" directory), and the "yum install kernel-devel" also needs an internet connection. I feel totally stuck, and I don't want to get a different card. Please help.
