I just upgraded from RH8 to RH9. My earlier instructions for getting Prism II worked just fine, using the linux-wlan RPMs compiled for RH9. According to this article, Red Hat improved things for users of WaveLAN wireless cards, but I think we Prism card owners still have to dance for our fix. The modules I ended up upgrading to (using “rpm -Uvh”) are kernel-wlan-ng-0.2.0-7, kernel-wlan-ng-modules-rh9.8-0.2.0-7 and kernel-wlan-ng-pcmcia-0.2.0-7, all for i686.
