Can I get my Yosemite to operate wirelessly under OS X? No problem under OS 9x with <a href="http://www.proxim.com/products/all/skyline/pn476bld/index.html" target="_blank">Proxim's PCI rig and Skyline 11 MB card</a>.

Since the Yosemite was pre-AirPort, Apple chose not to support it for wireless networking. I think it's a question of the PCI carrier for the card. System Profiler detects "something" but can't identify it. In my Network Panel I don't get the option to connect via AirPort or any other wireless card.
