Started crashing often, stopped finding stacks or people.

Question

Version 10 stopped finding stacks or people and started crashing all of the time. I can't manually add people, either. It throws an error message saying that the files need to be analyzed, but then still doesn't "find" them. I was looking for fixes and found information about renaming certain files, but I found out that my catalog isn't where the program thinks it is. I have no idea where it is, actually.
Edited:
I figured out that my library file was hidden, and so I was able to do the whole breeze session thing outlined here:
Resolve facial-recognition issues
I had been reading older posts that didn't take later versions of os x into consideration.
However, still when I run the "find people" or "find visually similar photos" I get no results. I literally have duplicate photos that it's saying aren't similar enough to stack. Again, I can't do this (or labeling people) manually.

Answer 1

I assume you mean that you have several wireless access points, not wireless routers.
Have your IT Dept disconnect the ethernet cable that connects the Access Point to the main switch or router, and then "tone" the wire to trace it.
Use one of these:

Another option is to flash the firwmare over the LAN, BUT that will probably default the Access Point to an address already in use and that may create a bigger problem.
