Lucent Orinoco Card
Seems the card is detected by Fedora core 2 as an ethernet card instead of a wireless ethernet card. This causes PCMCIA to not load. Edit /etc/sysconfig/networking/devices/ifcfg-eth0 (or whichever is your Orinoco card) and change TYPE from Ethernet to Wireless.
Run system-config-networking and then the Wireless tab will come up and let you enter ESSID, WEP keys, etc.
