I have noticed a quirk with the experimental reachability function which makes 
the function untrustworthy in some WIFI situations.

reachabilityChanged will sometimes return an empty reachabilityInfo. This is 
supposed to indicate no internet connection at all.
However, other apps are able to connect!

Has anyone else experienced this?

This only happens intermittently (don't you hate that word?!) and unfortunately 
I have no recipe to force it to happen.
Although sometimes moving a device into the range a different WIFI network will 
sometimes cause the problem.

I have found that sometimes the problem can sometimes be corrected by turning 
on and then off airplane mode or shutting on or off the device's wifi setting.

Needless to say, as it stands, this experimental function isn't 100% reliable 
yet. Even though it is a lower priority function, Apple does require apps to 
properly notify users when an internet connection is no longer viable - such as 
when one travels outside a WIFI network's range. So, we really do need this to 
work reliably.

Thanks,
Jim Lambert
