It may be that in the processing of upgrading to Yosemite, Control:Mac had the cached address of the Core flushed.

If you are not on hardwired connection, temporarily connect to wired ethernet and try Control:Mac again. It hopefully will discover the core and then cache the Core address allowing you to use wifi again.
