Hi
I also believe that ping data is one way to come up with an upper bound on just how awful WiFi timing can be. If others have a similar single shot measure of WiFi round trip that can be run on a wide range of devices, I’d certainly be just as interested in that.
does software like netstumbler and such have lower level diagnostic measurements?
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.
