does software like netstumbler and such have lower level diagnostic 

There's a variety of apps for my phones that provide some info on WiFi 
networks, but I think it's all sort of in the "received signal strength" 
kind of level.  I've not seen anything for timing.  But that's not to 
say that it doesn't exist.

I seem to recall some folks fooling with various timing parameters that 
can be set into 802.11 chipsets from 10 years ago.  Today's interfaces? 
I don't know.  The little interfaces that you put on a Arduino and such 
expose a serial port kind of interface with a AT command set.  I think 
they bury most all of the stuff we'd want to know about.
