no wifi adapter detected by Bodhi

Question

Installed bodhi-4.5.0-64 onto a 2008 Macbook, 4.1 and am not seeing wireless options.

Do I need to install something from apt first in order for Bodhi to pick up the built-in wifi adapter? The "network connection" GUI only shows the physical ethernet NIC.

not quite sure whether it was one specific install, or they were all required -- but it's working.
