This sample shows how to use the APIs to find out what kind of connectivity is available.
This sample started as a line-by-line port of the Apple sample, and it was too late when I realize that the sample was not very good to begin with. I have moved on to work on other things, but take this sample (and the Apple one) with a grain of salt, it does not use the best practices nor is it a great use of the APIs in the first place.
