I've tried setting up WPA2 Enterprise but have been unable to set it up in a way that works with all client hard/software in the enterprise. Windows was especially horrible. Most Linux distros and OSX seemed to kind of Just Work for the most part.

If anyone knows of a WPA2 Enterprise setup guide that works well with minimal hassle (no CA/certificate installation hell, Linux+BSD+OSX+Windows as old as 8), I'd be eternally grateful.
