How to check for internet connectivity and download file?

[Unknown W. Brackets]

Well, checking for internet connectivity is a tricky and 
operating-specific thing.

Would you rather check for connectivity with a specific host?  I gather 
that would be more than appropriate for what you're wanting.

Are you wanting to download over HTTP, or a different protocol?  If over 
HTTP, there are a ton of libraries that may be useful to you, and 
there's also building your own HTTP request (which is actually pretty 
trivial.)

If you're using Tango, it has classes in it for these things.
