It looks to me like they used an alternate driver to make that work.

It seems so, they were using a 'current' driver.
Using modinfo, I see that both my F26 and F32 are using the same driver, v4.1.4_6773.20130222.
Whereas the Monitor support was added to the driver circa Sep 2015.
So Fedora has been shipping a (very out of date?) driver.

It works with the Intel Centrino adapter in my laptop and also with the
two USB ones I tried.  One was a really old Airlink 101 and the other
was a tiny, cheap one that I got online with some Realtek chip that uses
the rtl8192cu driver.  The Airlink I couldn't switch to monitor mode
inside wireshark, I had to set it from the command line before for some
reason, but the others could be turned on by wireshark.

Try using your built-in wifi adapter.

I did (as mentioned), and it didn't get me anywhere, (Intel 3165)
I'll re-investigate though.

If you grabbed the whole screen, it was probably too big.  I've attached
a shot of just the area.

Yeah, that's what I see, except, I get dashes instead of the checkboxes.

Just checking, is your user in the wireshark group?  Do you even see
your network adapters in the list?

Yes
