Wireless was never easier for me than with RH 9.0. I suggest a couple of things:
Grab the latest orinoco_cs driver from David Gibson's site
, which is now 0.13e.
Use the orinoco_cs driver for either ORiNOCO or Prism cards.
Using "neat," the RH tool for network configuration, the entering of wireless parameters is quite straight-forward. If you want to manually enter things like WEP and ESSID, edit /etc/sysconfig/network-scripts/ifcfg-ethx where x is the number of your adapter.
